I. Introduction

A common problem in the Philippines is receiving calls, texts, or online messages from lending companies, financing apps, collection agents, or debt collectors about a loan that the phone owner did not apply for. Sometimes the person’s mobile number was used as a borrower’s number. In other cases, the number was listed as a “reference,” “co-maker,” “guarantor,” “emergency contact,” or “contact person” without the owner’s knowledge or consent.

This situation raises serious legal concerns. It may involve data privacy violations, unauthorized use of personal information, harassment by debt collectors, identity theft, fraud, cybercrime, and possible violations of lending and financing regulations.

In the Philippine setting, the key point is this: a person does not become liable for a loan merely because their phone number was used in a loan application without consent. A mobile number alone does not create a loan obligation, guarantee, suretyship, co-maker liability, or consent to be contacted for collection.

II. Typical Situations

Unauthorized use of a phone number in loan applications may happen in several ways.

1. The number is used as the borrower’s own number

Someone may apply for a loan using another person’s mobile number. The real owner of the number later receives collection texts, calls, OTP attempts, or verification messages.

2. The number is used as a character reference

Many online lending apps require borrowers to submit phone contacts, references, or emergency contacts. A borrower may list a friend, relative, co-worker, neighbor, or even a random number without asking permission.

3. The number is harvested from the borrower’s phone contacts

Some lending apps have been criticized for accessing a borrower’s contact list and using those contacts for collection pressure. A person may be contacted not because they agreed to be involved, but because their number appeared in someone else’s phonebook.

4. The number is listed as a guarantor or co-maker

A lender or collector may claim that the phone owner is a guarantor, co-maker, surety, or responsible party. In law, this claim is generally invalid unless the person actually agreed to such obligation in a legally binding manner.

5. The number is used for repeated loan applications

The same number may be used repeatedly by scammers, acquaintances, or borrowers who want to evade collection calls.

6. The number is used in fraudulent lending schemes

The incident may be part of a broader identity theft or scam, especially if other personal details were also used, such as name, address, valid ID, workplace, email address, or social media profile.

III. Is the Phone Number Owner Liable for the Loan?

Generally, no.

A loan is a contract. Under Philippine civil law principles, a person is bound by a contract only if they consented to it. Consent is an essential element of a valid contract. If a person did not apply for the loan, did not sign or electronically agree to the loan, did not receive the money, and did not authorize anyone to use their number, that person is not the borrower.

The use of a phone number, by itself, does not prove consent.

The phone owner is not liable merely because:

Their number was written in the application;
Their number appeared in the borrower’s contact list;
They were named as a reference;
They received OTPs or verification messages;
They were contacted by collectors;
The borrower is a relative or friend;
The borrower listed them as an emergency contact;
The lender’s records show their number.

A person may become liable only if there is a valid legal basis, such as personally borrowing money, signing as co-maker, agreeing to be a guarantor, or otherwise giving legally effective consent.

IV. Reference, Co-Maker, Guarantor, and Surety: Important Differences

Many collection problems arise because lenders or collectors confuse, or deliberately blur, the difference between a mere reference and a legally liable person.

A. Reference

A reference is usually a person identified by the borrower for verification or contact purposes. A reference is not automatically liable for the loan.

Being listed as a reference does not mean the person promised to pay.

B. Emergency contact

An emergency contact is someone who may be contacted in urgent situations. This does not create a debt obligation.

C. Co-maker

A co-maker is a person who signs or agrees to be jointly liable with the borrower. A co-maker may be made liable if there is a valid agreement.

But one cannot become a co-maker merely because their number was typed into a form.

D. Guarantor

A guarantor is a person who agrees to answer for the debt of another if the principal debtor fails to pay. Guaranty must be clear and legally established.

A guaranty is not presumed.

E. Surety

A surety is usually more directly liable than a guarantor because the surety binds themselves solidarily with the principal debtor. Like guaranty, suretyship requires a valid undertaking.

A person cannot be turned into a surety by the unilateral act of a borrower or lender.

V. Consent Is Essential

Consent is the foundation of contractual liability. In the context of a loan application, consent may be shown through a signature, electronic acceptance, verified account access, biometric verification, OTP confirmation, or other valid proof, depending on the platform and circumstances.

However, mere possession or use of a phone number does not necessarily prove consent.

A lender should not assume that the owner of a number agreed to be involved simply because the borrower entered that number in an application. Where a phone number is used without authorization, any supposed consent is defective or nonexistent.

VI. Data Privacy Issues

A mobile phone number is personal information. When connected with a person’s name, address, account, debt, contact list, or other identifying details, it becomes part of a person’s protected personal data.

The unauthorized collection, use, disclosure, storage, or processing of a phone number may raise issues under the Data Privacy Act of 2012.

A. Personal information

A phone number may identify or be linked to a specific person. It is personal information when it can reasonably identify an individual.

B. Processing requires lawful basis

Entities that collect or use personal data must have a lawful basis for processing. Consent is one possible basis, but it is not the only one. Still, where a person’s phone number is used in a loan application without permission, the lender must be able to justify why it collected, stored, used, or contacted that number.

C. Data minimization

Lending companies should collect only data that is necessary and proportionate for a legitimate purpose. Excessive collection of contacts, call logs, photos, social media data, or unrelated phonebook entries may be questionable.

D. Transparency

Individuals should know how their data is collected, used, shared, and stored. If a person’s number is used as a reference or contact, they should not be kept in the dark about how their data is being processed.

E. Rights of the data subject

A person whose number was used without consent may assert data privacy rights, including:

The right to be informed;
The right to access information about the processing;
The right to object to processing;
The right to correction or rectification;
The right to erasure or blocking;
The right to damages, where legally proper;
The right to file a complaint with the proper authority.

VII. What If the Lending Company Contacts You?

If a lending company contacts a person about a loan they did not apply for, the person should be careful not to accidentally admit liability.

A proper response may include:

State clearly that you did not apply for the loan.
State that you did not authorize use of your phone number.
State that you are not the borrower, co-maker, guarantor, or surety.
Ask them to remove your number from their records.
Ask for the identity of the company, loan account reference, and basis for contacting you.
Demand that they stop contacting you for collection.
Save evidence of all communications.

The phone owner should avoid saying things like:

“I will tell the borrower to pay.”
“I will try to settle this.”
“Give me time.”
“I will pay later.”
“I promise to talk to them.”

Such statements may be misused by aggressive collectors, even if they do not legally create liability.

VIII. Collection Harassment

Some collectors use threats, shame tactics, repeated calls, social media exposure, or intimidating messages. These may be unlawful depending on the content, frequency, and manner.

Common abusive practices include:

Repeated calls at unreasonable hours;
Threatening arrest for nonpayment of a civil debt;
Threatening to post the person’s photo or name online;
Calling the person’s employer;
Sending messages to relatives, co-workers, or friends;
Claiming that the person is criminally liable without basis;
Using insults, profanity, or humiliation;
Pretending to be a lawyer, police officer, court sheriff, or government employee;
Sending fake subpoenas, warrants, or court notices;
Publicly shaming the alleged borrower or contacts;
Disclosing debt information to third parties;
Threatening physical harm.

A person whose number was used without consent should document these acts because they may support complaints before regulators or law enforcement.

IX. Can a Person Be Arrested for a Loan They Did Not Make?

No, a person cannot be arrested merely because someone else used their phone number in a loan application.

Even for the actual borrower, nonpayment of debt is generally a civil matter, not automatically a criminal offense. However, criminal liability may arise in cases involving fraud, deceit, falsification, identity theft, estafa, or other punishable acts.

For the innocent phone owner, the key defenses are:

No consent;
No loan application;
No receipt of loan proceeds;
No signature or valid electronic acceptance;
No agreement to be guarantor or co-maker;
Unauthorized use of personal information.

X. Possible Legal Violations by the Person Who Used the Number

The person who entered or used another person’s phone number without consent may be exposed to liability depending on the facts.

A. Fraud or misrepresentation

If the borrower knowingly submitted false information to obtain a loan, this may constitute fraud or misrepresentation. If the misrepresentation induced the lender to release money, criminal or civil consequences may arise.

B. Identity theft

If the borrower used not only the phone number but also the name, ID, address, photo, signature, or other identifying information of another person, the act may amount to identity theft or a related cybercrime.

C. Falsification

If documents, signatures, IDs, or electronic records were falsified, criminal liability for falsification may be involved.

D. Estafa

If deceit was used to obtain money from the lender, the borrower may potentially face estafa, depending on the elements and evidence.

E. Violation of data privacy rights

The unauthorized use or disclosure of personal information may also raise data privacy concerns.

XI. Possible Liability of the Lending Company

A lender or online lending platform may also be liable if it improperly collects, processes, uses, or discloses the phone owner’s personal data.

Possible issues include:

1. Failure to verify consent

If a company treats a person as a reference, guarantor, co-maker, or contact without verifying consent, it may be engaging in unfair or improper processing.

2. Unlawful or excessive collection

If the company accesses or uses contact lists beyond what is necessary, it may violate data privacy principles.

3. Unauthorized disclosure of debt information

Disclosing a borrower’s alleged debt to unrelated third parties may violate privacy rights. Debt information is sensitive in practical effect and may cause reputational harm.

4. Harassment and abusive collection

A lending company may be responsible for abusive acts committed by its employees, agents, or third-party collectors.

5. Misrepresentation

Collectors who falsely claim that a reference is legally liable may engage in deceptive or unfair practices.

6. Failure to honor data subject rights

If a person demands removal of their number and the company continues to process it without lawful basis, this may strengthen a complaint.

XII. Online Lending Apps and Contact List Abuse

The Philippines has seen many complaints involving online lending apps that access phone contacts and use them for pressure collection.

This may happen when the borrower grants app permissions to access contacts. However, even if the borrower granted access, the people in the borrower’s contact list did not necessarily consent to being contacted, profiled, harassed, or used for collection.

Important points:

Consent by the borrower is not automatically consent by everyone in the borrower’s phonebook.
A contact number in someone’s phone does not mean the contact person agreed to be part of a loan transaction.
Contacting third parties may be improper if it discloses the debt or pressures unrelated persons.
Debt collection should be directed at the actual debtor and legally liable parties, not innocent contacts.

XIII. SIM Registration and Unauthorized Number Use

The SIM Registration Act requires registration of SIMs in the Philippines. However, SIM registration does not prevent all misuse.

A registered SIM may still be:

Used by another person with access to the phone;
Entered manually into an online loan form;
Spoofed or impersonated;
Used as a reference without consent;
Recycled by a telecommunications provider;
Used by scammers who obtained the number from public posts, forms, leaks, or contact lists.

If a number is repeatedly misused, the subscriber may consider reporting to the telecommunications provider and relevant authorities.

XIV. Recycled Phone Numbers

A person may receive collection calls because the number previously belonged to another subscriber.

This is common when a telco reassigns inactive numbers.

In such cases, the current subscriber should inform the lender that:

They are the current user of the number;
They are not the borrower;
They do not know the borrower, if true;
The number may have been reassigned;
The lender should update its records and stop contacting the number.

The current subscriber should not be forced to prove the old borrower’s whereabouts or pay the old borrower’s debt.

XV. What Evidence Should Be Preserved?

Evidence is critical. The phone owner should keep:

Screenshots of text messages;
Call logs showing date, time, and number;
Voice recordings, if lawfully obtained;
Names of collectors or agents;
Company name and address;
Loan app name;
Account reference number;
Copies of demand letters or emails;
Social media messages;
Threatening or defamatory posts;
Proof that the number belongs to the complainant;
Proof that the complainant did not apply for the loan;
Any request for removal or cease-contact message;
Any response or refusal from the company.

Where possible, screenshots should show the date, time, sender, and full message.

XVI. Immediate Steps for the Phone Owner

A person whose number was used without consent may take the following steps.

Step 1: Do not panic and do not pay

Payment may be misinterpreted as acknowledgment. If the person did not borrow money or agree to be liable, they should not pay merely to stop harassment.

Step 2: Do not give additional personal information

Collectors may ask for ID, address, workplace, or relatives’ names. The person should avoid giving more personal data unless dealing with a verified authority or making a formal complaint.

Step 3: Ask for the company’s identity

Ask for the registered name of the company, office address, agent name, and basis for contacting the number.

Step 4: Deny liability clearly

State that the number was used without consent and that the person is not the borrower, co-maker, guarantor, surety, or authorized reference.

Step 5: Demand removal of the number

Request deletion, blocking, or removal of the number from the loan account and collection database.

Step 6: Save evidence

Preserve every message, call log, and communication.

Step 7: Block if necessary

Blocking may help stop harassment, but evidence should be saved first.

Step 8: File complaints if harassment continues

Depending on the facts, complaints may be filed with the National Privacy Commission, Securities and Exchange Commission, Bangko Sentral ng Pilipinas, police cybercrime units, the National Bureau of Investigation Cybercrime Division, telecommunications providers, or the proper court.

XVII. Sample Message to Lending Company or Collector

A person may send a clear written notice such as:

I am the owner/user of this mobile number. I did not apply for any loan with your company. I did not authorize any person to use my number for a loan application. I am not the borrower, co-maker, guarantor, surety, or authorized reference for the alleged loan.

Please immediately remove my number from your records and stop contacting me regarding this account. Any continued use of my number, disclosure of alleged debt information, or harassment may be reported to the appropriate authorities.

This message should be sent in a way that can be documented, such as SMS, email, app chat, or official complaint channel.

XVIII. When to File a Complaint with the National Privacy Commission

A complaint with the National Privacy Commission may be appropriate when the issue involves unauthorized collection, use, disclosure, retention, or processing of personal data.

Possible grounds include:

Your phone number was processed without consent or lawful basis;
The lending company refuses to remove your number;
The company disclosed debt information to you or others without justification;
The app accessed contacts excessively;
Collectors used your personal information to harass or shame you;
Your number, name, photo, or social media profile was used without authority;
The company ignored your data subject rights.

Before filing, it is often helpful to first send a written request or complaint to the company’s data protection officer or official contact channel, if known.

XIX. When to File a Complaint with the SEC

Many lending companies and financing companies in the Philippines are regulated by the Securities and Exchange Commission. A complaint with the SEC may be appropriate if the entity is a lending company, financing company, or online lending platform engaged in abusive, unfair, deceptive, or illegal collection practices.

Potential issues include:

Harassment by collectors;
Threats and intimidation;
Public shaming;
Misleading claim that a non-borrower is liable;
Use of unauthorized contacts;
Collection from third persons who are not debtors;
Operating without proper registration or authority;
Abusive online lending practices.

The SEC may act against registered entities and may also address unauthorized lending operations within its regulatory authority.

XX. When to File a Complaint with the BSP

The Bangko Sentral ng Pilipinas may be relevant if the entity involved is a BSP-supervised financial institution, such as a bank, certain financing or lending-related financial service provider, or electronic money issuer.

A BSP complaint may be appropriate if the harassment or unauthorized use of personal information involves a BSP-regulated institution or financial product.

XXI. When to Report to the NBI or PNP Cybercrime Units

A report to cybercrime authorities may be appropriate when the incident involves:

Identity theft;
Use of your personal data in an online loan application;
Fake accounts;
Phishing;
Unauthorized OTP attempts;
Threatening messages sent online;
Defamatory posts;
Fake legal documents;
Social media harassment;
Online extortion;
Unauthorized use of IDs, photos, signatures, or accounts.

If the loan application was made online using another person’s identity or details, cybercrime issues may arise.

XXII. When to Report to the Telecommunications Provider

A report to the telco may be useful when:

The number receives repeated scam calls or texts;
There are suspicious OTP messages;
There may be SIM swap or unauthorized SIM activity;
The number may have been recycled;
The subscriber wants records or assistance;
The misuse continues despite demands.

The telco may not resolve the debt issue, but it may help with account security, SIM concerns, or documentation.

XXIII. Civil Remedies

Depending on the facts, the aggrieved person may pursue civil remedies.

A. Damages

If unauthorized use of a phone number caused mental anguish, reputational harm, business disruption, loss of employment opportunities, or other injury, the person may consider a claim for damages.

Possible damages may include actual, moral, exemplary, or nominal damages, depending on the evidence and legal basis.

B. Injunction

If harassment is continuing, a court remedy may be considered to restrain unlawful acts.

C. Correction or deletion of records

The person may demand that the lender correct, block, or delete unauthorized data.

D. Defamation-related remedies

If the lender, collector, or borrower publicly accused the person of being a debtor, scammer, or criminal, defamation issues may arise.

XXIV. Criminal Law Considerations

Unauthorized use of a number can intersect with criminal law.

A. Estafa

If a borrower used false pretenses to obtain a loan, estafa may be considered, depending on the evidence and timing of deceit.

B. Identity theft

If another person’s identifying information was used online or electronically without authority, identity theft or related cybercrime provisions may be implicated.

C. Falsification

If signatures, IDs, or documents were forged, falsification may be involved.

D. Unjust vexation, grave coercion, or threats

Collectors who harass, threaten, or intimidate an innocent person may expose themselves to criminal complaints depending on the acts committed.

E. Libel or cyberlibel

If false accusations are posted online or sent through electronic means to damage reputation, cyberlibel may be relevant.

F. Illegal access or misuse of accounts

If the perpetrator accessed the person’s phone, email, online account, or OTPs without authority, additional cybercrime issues may arise.

XXV. OTPs and Verification Messages

Receiving an OTP or verification code from a lending app may mean someone attempted to use the number to register, log in, or apply.

The safest response is:

Do not share the OTP with anyone;
Do not click suspicious links;
Screenshot the message;
Report the unauthorized attempt to the app or lender;
Secure related accounts;
Consider changing passwords if the incident appears connected to broader account compromise.

An OTP sent to a number does not mean the owner consented to the loan. Consent should not be inferred from an OTP unless the owner actually used it to proceed with the transaction.

XXVI. What If the Borrower Is a Relative?

Many cases involve relatives using someone’s number as a reference or emergency contact. The legal principles remain the same.

A person is not liable for a relative’s loan unless they legally agreed to be liable.

Parents are generally not liable for adult children’s debts. Children are generally not liable for parents’ debts. Siblings are not automatically liable for each other’s debts. Spouses have special property and obligation rules, but even then, a spouse is not automatically liable for every personal loan of the other spouse; the nature, purpose, consent, and property regime may matter.

Collectors often pressure family members because they are easier to find than the borrower. That does not mean the family member has a legal obligation to pay.

XXVII. Spouses and Unauthorized Loan Applications

A spouse’s phone number may be used in a loan application without consent. Whether the other spouse or the conjugal/community property may be affected depends on several factors, including:

Whether the loan benefited the family;
Whether the loan was contracted during the marriage;
Whether the spouses are under absolute community or conjugal partnership;
Whether the loan was for personal, business, or family purposes;
Whether the spouse consented;
Whether the lender can prove the obligation.

Even between spouses, unauthorized use of a number does not automatically create personal liability.

XXVIII. Employers, Co-Workers, and Workplace Harassment

Collectors may call employers or co-workers to shame the alleged borrower or pressure payment. This can create separate legal problems.

For a person whose number was used without consent, workplace calls may cause embarrassment, reputational harm, or employment issues.

The person should document:

Who called;
What was said;
Whether debt information was disclosed;
Whether threats were made;
Whether the caller claimed legal authority;
Whether the employer or co-worker received messages.

Unauthorized disclosure of debt-related information to an employer may be especially serious.

XXIX. Social Media Exposure

Some abusive collectors send messages to Facebook friends, tag relatives, post photos, or create group chats to shame a borrower or alleged contact.

If the phone owner is not the borrower, such acts may be particularly damaging. They may implicate privacy violations, cyberlibel, harassment, unjust vexation, or other legal remedies.

The person should immediately preserve screenshots showing:

URL or profile link;
Date and time;
Names of participants;
Exact words used;
Photos or documents posted;
Comments and reactions;
Sender identity, if visible.

XXX. Debt Collection Must Be Lawful

Creditors have a right to collect lawful debts. However, debt collection must be done within legal limits.

A collector should not:

Threaten arrest without basis;
Use abusive language;
Call repeatedly to harass;
Contact unrelated persons to shame the borrower;
Publicly disclose debt information;
Misrepresent legal consequences;
Pretend to be from the court, police, NBI, prosecutor’s office, or law office;
Demand payment from someone who is not legally liable;
Continue processing a person’s number after being told it was used without consent, unless there is a valid legal basis.

XXXI. How to Determine Whether the Lender Is Legitimate

A person contacted by a lender should ask for:

Registered corporate name;
SEC registration details, if applicable;
Certificate of authority, if applicable;
Business address;
Official website or email;
Name of data protection officer;
Name and authority of collector;
Loan account reference;
Basis for contacting the number;
Copy or proof of alleged consent, if they claim the person agreed.

If the caller refuses to identify the company or uses only a generic app name, that may be a warning sign.

XXXII. What If the Lender Insists You Are a Co-Maker?

Ask for proof.

A valid co-maker obligation should not rest on a mere phonebook entry or a typed mobile number. The lender should produce evidence that the person actually agreed to be a co-maker.

Relevant proof may include:

Signed document;
Valid electronic contract;
Clear acceptance record;
Identity verification;
OTP logs connected to the person’s actual act;
Proof of disclosure of terms;
Proof that the person knowingly agreed to be liable.

Without proof of consent, the claim of co-maker liability is weak.

XXXIII. What If the Lender Says the Borrower Gave Consent?

The borrower can consent only for the borrower’s own data and obligations. A borrower generally cannot authorize the use of another person’s personal data in a way that creates legal liability for that other person.

The borrower also cannot make another person a guarantor or co-maker without that person’s consent.

A lender relying solely on the borrower’s representation should still be careful, especially when the lender later contacts or processes the data of third parties.

XXXIV. What If the Number Was Publicly Available?

A phone number being public does not automatically mean anyone may use it for a loan application or debt collection.

For example, a number posted on a business page may be used for customer inquiries, not for someone else’s loan application. Public availability does not erase privacy rights or contractual consent requirements.

Purpose matters. Using a public number for an unrelated loan application may still be improper.

XXXV. What If the Phone Owner Knows the Borrower?

Knowing the borrower does not create liability.

A person may know, work with, live near, or be related to the borrower without being responsible for the borrower’s debt.

A collector may ask the phone owner to relay a message. The phone owner may refuse. There is generally no duty to act as a collection agent for the lender.

XXXVI. What If the Phone Owner Was Actually a Reference But Did Not Consent?

Even if the borrower listed the person as a reference, the person may object if they did not consent.

A reference does not owe the debt. At most, a reference may confirm limited information if they voluntarily choose to do so. They may also refuse to answer.

The lender should not repeatedly contact, threaten, shame, or pressure a reference to pay.

XXXVII. What If the Person Accidentally Confirmed Information?

Sometimes a collector calls and asks, “Are you Mr. X?” or “Do you know Ms. Y?” The person may answer without understanding that the call relates to debt collection.

Accidentally confirming identity or acquaintance does not make the person liable for the debt.

However, after realizing the situation, the person should clearly state that they do not consent to further contact and are not legally liable.

XXXVIII. What If the Person Paid to Stop the Harassment?

Payment by a non-borrower can complicate matters. The person may consider whether the payment can be recovered, especially if made because of threats, fraud, intimidation, or mistake.

Possible remedies may include:

Demand for refund;
Complaint against the lender or collector;
Civil action, depending on amount and evidence;
Complaint based on harassment or misrepresentation.

The person should preserve proof of payment, messages, and the circumstances that led to payment.

XXXIX. Protecting Yourself Against Future Misuse

Practical preventive measures include:

Do not publicly post your personal mobile number unnecessarily;
Use separate numbers for business and personal matters;
Avoid sharing OTPs;
Avoid lending your SIM or phone to others;
Review app permissions;
Be cautious with online forms and raffles;
Remove your number from public posts when no longer needed;
Use privacy settings on social media;
Monitor suspicious messages;
Report unauthorized loan verification attempts immediately.

XL. Demand Letter or Complaint Letter

A person may send a formal written demand to the lender. The demand may include:

Identification of the complainant as the owner/user of the number;
Statement that the number was used without consent;
Denial of loan liability;
Demand for proof of alleged consent, if any;
Demand to stop contacting the number;
Demand to delete, block, or correct the personal data;
Warning that continued contact may result in complaints;
Request for written confirmation of compliance.

The letter should be calm, factual, and documented.

XLI. Sample Formal Demand

Subject: Unauthorized Use of Mobile Number and Demand to Cease Collection Contact

To Whom It May Concern:

I am the owner/user of mobile number [insert number]. I received calls/messages from your company regarding a loan account allegedly connected with this number.

I did not apply for any loan with your company. I did not authorize any person to use my mobile number for any loan application. I am not the borrower, co-maker, guarantor, surety, reference, or emergency contact for the alleged account.

Accordingly, I demand that your company immediately:

Stop contacting me regarding the alleged loan;
Remove, block, or delete my mobile number from the loan account and collection database;
Refrain from disclosing my number or any information about me to collectors or third parties;
Provide written confirmation that my number has been removed;
Provide the name of your data protection officer or authorized representative handling this concern.

Please treat this as a formal objection to the unauthorized processing of my personal information. Continued contact, harassment, or disclosure may compel me to file complaints with the appropriate government agencies and pursue available legal remedies.

Sincerely, [Name]

XLII. If the Number Was Used Together With Your Name or ID

The case becomes more serious if the loan application used not only the phone number but also:

Full name;
Address;
Date of birth;
Government ID;
Selfie photo;
Signature;
Employment details;
Bank account;
E-wallet account;
Email address;
Social media account.

This may indicate identity theft or a larger data breach. The person should consider:

Reporting immediately to the lender;
Asking for a copy of the application or transaction records;
Filing a data privacy complaint;
Reporting to cybercrime authorities;
Notifying banks or e-wallet providers;
Monitoring credit or financial accounts;
Executing an affidavit of denial or affidavit of unauthorized use, if needed.

XLIII. Affidavit of Denial or Unauthorized Use

An affidavit may help document the person’s position. It may state that:

The affiant owns or uses the mobile number;
The affiant did not apply for the loan;
The affiant did not authorize use of the number;
The affiant did not receive loan proceeds;
The affiant is not a co-maker, guarantor, surety, or reference;
The affiant received collection calls or messages;
The affiant requests investigation and removal of the number.

An affidavit does not automatically resolve the matter, but it may support complaints, telco reports, police reports, and correspondence with lenders.

XLIV. Role of Barangay Proceedings

Barangay conciliation may be relevant if the person who used the number is known and resides in the same city or municipality, and the dispute falls within barangay conciliation rules.

For example, if a neighbor or relative used the number without permission, the aggrieved person may consider barangay action to demand that the borrower correct the record and stop using the number.

However, complaints involving corporations, cybercrime, data privacy violations, or urgent harassment may require direct action with the appropriate agency or court instead.

XLV. Small Claims and Civil Collection Cases

If a lender files a case against the wrong person, the person should not ignore court papers. They should respond according to the rules and raise defenses such as:

Lack of consent;
No contract;
Mistaken identity;
No receipt of loan proceeds;
No co-maker or guaranty agreement;
Unauthorized use of personal information;
Lack of cause of action;
Improper party.

Ignoring official court notices can lead to procedural consequences even if the claim is baseless.

XLVI. Distinguishing Real Court Documents From Fake Threats

Collectors sometimes send fake legal-looking documents. A real court document usually comes from an actual court, bears a case number, names the court, and is served according to proper procedure.

Warning signs of fake threats include:

“Warrant of arrest” for simple nonpayment of loan;
“Final warning before police arrest” from a private collector;
Threats from supposed “cybercrime court” without case details;
Demand to pay immediately to avoid imprisonment;
Refusal to provide company identity;
Threats sent only by random SMS or chat account;
Bad grammar and generic templates;
Use of seals or logos without authority.

Even if the document looks suspicious, preserve it as evidence.

XLVII. If the Lender Threatens to Visit Your Home

A lender or collector cannot lawfully trespass, threaten, embarrass, or coerce a non-borrower.

If a collector visits:

Do not let them enter without consent;
Ask for identification;
Do not sign anything without understanding it;
Record details of the visit, if lawful and safe;
Have a witness present;
Call barangay officials or police if there are threats or disturbance;
Repeat that you are not the borrower and did not authorize the use of your number.

XLVIII. If the Lender Contacts Your Family or Friends

If the lender contacts other people about a loan you did not make, preserve evidence and consider a stronger complaint. This may involve unauthorized disclosure, harassment, or reputational harm.

You may send a written demand instructing the company to stop contacting third parties and to remove your number from all records connected to the alleged loan.

XLIX. If Your Phone Number Is Used Repeatedly

Repeated misuse may suggest that your number is circulating in databases, old loan records, contact lists, scam networks, or recycled-number records.

Actions to consider:

Send formal demands to each lender;
File complaints against repeat offenders;
Report scam messages to the telco;
Consider changing number if the harassment is severe, though this should not be necessary in principle;
Maintain a file of incidents;
Use call filtering and spam blocking tools;
Avoid engaging with unknown collectors beyond one clear denial and demand to stop.

L. Remedies Against the Borrower

If you know who used your number, you may demand that the borrower:

Correct the loan application;
Notify the lender that your number was used without consent;
Remove your number from all apps and accounts;
Stop using your number in future applications;
Indemnify you for damages caused by harassment or complaints.

If the borrower used your identity or documents, stronger criminal and civil remedies may be available.

LI. Practical Complaint Package

A strong complaint file may include:

Narrative summary of events;
Your contact details;
Proof you own or use the number;
Screenshots of messages;
Call logs;
Names and numbers of collectors;
Company or app name;
Copies of demands sent;
Proof of continued harassment after demand;
Social media screenshots, if any;
Affidavit of denial, if available;
Any proof that the actual borrower is another person;
Any proof of identity theft or unauthorized data use.

Organized evidence makes it easier for regulators, police, lawyers, or courts to understand the case.

LII. Frequently Asked Questions

1. Am I liable if my number was used in a loan application?

No, not merely because your number was used. Liability requires a valid legal basis, such as your own loan application or clear agreement to be a co-maker, guarantor, or surety.

2. Can a lender force me to pay because I am a reference?

No. A reference is not automatically liable for the borrower’s debt.

3. Can a borrower make me a guarantor without my consent?

No. Guaranty or suretyship requires your consent. It cannot be created by another person listing your number.

4. Can collectors keep calling me?

They should not continue contacting you for collection after you clearly state that you are not the borrower and your number was used without consent, unless they have a lawful and legitimate basis.

5. Should I block the number?

You may block abusive numbers after saving evidence. But if you plan to file a complaint, preserve screenshots and call logs first.

6. Can I sue if they shame me online?

Possibly, depending on the statements, evidence, and damage. Cyberlibel, privacy violations, harassment, or civil damages may be considered.

7. What if I know the borrower?

You still are not liable unless you legally agreed to be liable.

8. What if the borrower is my spouse?

Spousal liability depends on facts such as consent, benefit to the family, property regime, and proof of obligation. Unauthorized use of your number alone does not automatically make you liable.

9. What if I received an OTP?

Do not share it. Receiving an OTP does not mean you consented to the loan.

10. What if the company says I must prove I am not the borrower?

You can deny liability and demand proof of their claim. The party asserting liability generally must prove the basis of that liability.

11. Can I demand deletion of my number?

Yes, you may demand deletion, blocking, correction, or removal if your number is being processed without lawful basis.

12. Can I file a complaint even if I suffered no financial loss?

Yes. Privacy violations, harassment, and unauthorized data processing may be actionable even if you did not pay money, depending on the circumstances.

LIII. Key Legal Principles

The most important legal principles are:

A loan requires consent.
A phone number alone does not create debt.
A person cannot be made a co-maker, guarantor, or surety without agreement.
A reference is not a debtor.
A borrower cannot consent on behalf of another person’s personal data and legal liability.
Debt collection must be lawful and non-abusive.
Personal data must be processed fairly, lawfully, and transparently.
Unauthorized use of personal information may lead to civil, criminal, regulatory, or administrative consequences.
Harassment, threats, public shaming, and false accusations may create separate liability.
Evidence should be preserved early.

LIV. Conclusion

When a phone number is used for a loan application without consent in the Philippines, the phone owner should understand that use of the number does not automatically create liability. A person is not a borrower, co-maker, guarantor, surety, or legally responsible party simply because their mobile number was entered in an application or appeared in someone’s contact list.

The incident should be treated as both a debt collection issue and a personal data protection issue. If collectors contact the number, the owner should clearly deny liability, demand removal of the number, preserve evidence, and report continued harassment or unauthorized processing to the proper authorities.

The strongest response is calm, documented, and firm: deny the loan, deny consent, demand deletion or correction, refuse to pay a debt that is not yours, and pursue complaints if the lender, borrower, or collector continues unlawful conduct.
