Receiving collection texts, calls, or demand notices addressed to someone you do not know usually means your mobile number previously belonged to the borrower, was entered incorrectly, or was listed as a contact or character reference. It does not automatically mean that you owe the debt. The safest response is to document the messages, verify the sender independently, send a written correction request, and escalate the matter if the creditor or collection agency continues contacting you.

Why collection agencies are contacting your number

Your mobile number may have been reassigned

Philippine telecommunications companies can permanently disconnect inactive prepaid SIMs and later reassign their mobile numbers. Globe’s current prepaid terms, for example, expressly state that a permanently disconnected number may be reassigned to another subscriber. A creditor’s old database may therefore still associate your newly acquired number with the previous subscriber. (Globe Telecom)

Registration under the SIM Registration Act, Republic Act No. 11934 of 2022 identifies the current registered user of the SIM. It does not automatically update the separate records of banks, lending companies, online loan applications, collection agencies, e-wallets, retailers, or utility providers. (Lawphil)

The borrower may have entered the wrong number

A single incorrect digit can cause collection notices to reach an innocent person. The creditor may also have an outdated number that previously belonged to a relative, employee, tenant, customer, or acquaintance of the borrower.

Your number may have been listed as a character reference

Some loan applications ask borrowers to provide contact persons for identity verification. An applicant may have entered your number without telling you, or an online lending application may have accessed contact information stored on the applicant’s phone.

Under the National Privacy Commission’s amended rules for loan-related transactions, a character reference is not automatically a guarantor. The lender must inform the reference that their details were provided, explain how the details were obtained, and offer an option to remove the information. A lender may not contact people in the borrower’s contact list for debt collection unless they were properly declared as guarantors. (National Privacy Commission)

The message may be fraudulent

Not every supposed “collection notice” comes from a legitimate creditor. Warning signs include:

Requests for an OTP, password, PIN, or complete card details
Payment instructions involving a personal GCash or Maya account
Shortened or misspelled website links
Refusal to identify the original creditor
Threats of immediate arrest for an ordinary unpaid loan
Demands that you pay first before the sender explains the account
Messages that contain no borrower name, account reference, or company information

Verify the sender through the creditor’s official website, mobile application, hotline, or published email address. Do not rely solely on a telephone number or link contained in the collection message.

Are you responsible for the former user’s debt?

Ordinarily, no. A mobile number is only contact information. Acquiring or registering that number does not make you a party to the former subscriber’s loan, credit card agreement, installment purchase, or other obligation.

Under Articles 1157 and 1159 of the Civil Code of the Philippines, Republic Act No. 386, obligations arise from recognized legal sources, including contracts, and contractual obligations bind the contracting parties. Article 1311 further provides that contracts generally take effect only between the parties, their assigns, and their heirs, subject to recognized exceptions. Simply becoming the current user of a telephone number is not one of those exceptions. (Lawphil)

You could become legally responsible only if there is an independent basis, such as:

You personally signed or accepted the loan agreement.
You expressly agreed to be a guarantor or surety.
You used another person’s account or credit facility.
Your identity was used and the creditor’s records actually identify you as the borrower.
A court determines liability based on evidence other than your possession of the phone number.

A guarantor is someone who expressly agrees to answer for the borrower’s obligation if the borrower fails to pay. The NPC’s loan-related privacy rules require the guarantor’s separate consent. Being saved in someone’s contacts, named as a friend, or called by a collector does not by itself create a guaranty. (National Privacy Commission)

Your data privacy rights

A telephone number associated with an identifiable person is personal information. Using your number, recording calls to it, associating it with a loan account, and repeatedly sending messages are forms of personal-data processing.

Under Section 16 of the Data Privacy Act of 2012, Republic Act No. 10173, a data subject may:

Ask whether their personal information is being processed.
Request reasonable access to information about the processing, including the source of the data.
Dispute inaccurate information and request its correction.
Seek blocking, removal, or destruction when information is false, outdated, unlawfully obtained, used for unauthorized purposes, or no longer necessary.
Claim appropriate relief for damage caused by inaccurate or unauthorized processing. (National Privacy Commission)

These rights do not necessarily entitle you to receive the former borrower’s complete loan file. That file contains another person’s private information. What you may reasonably request is information about your telephone number, including:

How the company obtained it
Why it is being processed
Whether it is classified as the borrower’s number, a reference, or a guarantor’s number
Which collection agency or service provider received it
Whether it has been corrected, blocked, or placed on a do-not-contact list

A creditor may retain the former borrower’s legitimate account records for legal, regulatory, or evidentiary purposes. However, that does not ordinarily require it to continue using your number after being told that the association is inaccurate. A practical correction is to mark the number as “wrong party,” suppress it from collection campaigns, and notify collection agents that previously received it.

Rules against abusive collection practices

Different regulators supervise different types of creditors, but Philippine law generally requires fair and reasonable collection conduct.

Banks, credit card issuers, and BSP-supervised institutions

The Financial Products and Services Consumer Protection Act, Republic Act No. 11765 of 2022 prohibits financial service providers from using abusive collection or debt-recovery practices. It also requires consumer-assistance mechanisms and protection of client data.

BSP Circular No. 1160 requires Bangko Sentral-supervised institutions and their collection agencies, lawyers, and other agents to observe good faith, reasonable conduct, and professional treatment. A bank remains accountable for records referred to its collection providers.

Lending and financing companies

The Securities and Exchange Commission’s Memorandum Circular No. 18, Series of 2019 prohibits unfair collection practices by lending and financing companies. Prohibited conduct includes violence or threats, insults, deceptive representations, publication of borrowers’ personal information outside recognized exceptions, and contact at unreasonable hours. (SEC Appointment System)

Privacy rules for online lenders

NPC Circular Nos. 2020-01 and 2022-02 regulate the processing of personal data in loan-related transactions. They prohibit excessive or disproportionate processing that results in harassment or unfair collection. They also prohibit contacting people in a borrower’s contact list for collection unless those people were declared and properly engaged as guarantors. (National Privacy Commission)

What to do when you receive a collection notice for someone else

1. Preserve evidence before blocking the sender

Take screenshots showing:

The entire message
The sender’s number or registered sender name
Date and time
Name of the alleged borrower
Name of the creditor or collection agency
Account or case reference number
Payment instructions
Threats, insults, or links

Keep a simple log of calls. Record the date, time, caller’s name, company, callback number, and what was said. Do not secretly publish recorded conversations; preserve them for complaints or proceedings where lawfully relevant.

2. Verify the company independently

Look up the original creditor through an official source. Ask:

What is the company’s complete legal name?
Is the caller an employee or an external collection agency?
Who is the original creditor?
What account reference are they contacting you about?
What is the official email address of the company’s consumer-assistance unit or data protection officer?

Do not provide your date of birth, address, government ID number, banking details, or OTP merely to prove that you are not the borrower.

3. Send one clear written wrong-number notice

Send the notice to the creditor’s official customer-service or consumer-assistance address, not only to the individual collector. Copy the collection agency and the company’s data protection officer when their addresses are available.

A practical notice may read:

I am the current user of mobile number 09XX-XXX-XXXX. I am not the person named in your collection messages, I did not obtain or guarantee the alleged loan, and I do not know whether the former user of this number has any obligation to your company.

Please correct your records, mark this number as belonging to the wrong person, stop all collection calls and messages to it, and instruct your collection agents and service providers to do the same.

Under the Data Privacy Act, please confirm the source of my number, the purpose for which it is being processed, whether it was recorded as a borrower’s number, character reference, or guarantor’s number, and the action taken to rectify or block it.

This notice is not an acknowledgment of the alleged debt. Please confirm in writing when the correction has been completed.

Include the relevant account reference but avoid repeating unnecessary personal information about the alleged borrower.

4. Provide only proportionate proof

A company may reasonably ask for evidence that you control the number. Depending on the circumstances, you may provide:

A recent postpaid bill showing your name and number
A screenshot from the telco’s official application
A SIM registration confirmation
A telco account page showing the number
A redacted service contract or official receipt

Mask unrelated information, including balances, complete addresses, QR codes, signatures, account passwords, and government ID numbers. A full unredacted ID should not be the default response to a wrong-number complaint.

5. Give the company a reasonable opportunity to correct its records

There is no single statutory response period that applies to every creditor and every correction request. As a practical measure, ask for acknowledgment within three to five business days and a substantive response within 10 to 15 calendar days.

For a formal NPC complaint, the complainant generally must first notify the respondent in writing and give it an opportunity to act. The NPC’s current rules require proof that the respondent failed to take timely or appropriate action, or did not respond within 15 calendar days after receiving the written notice. (National Privacy Commission)

6. Block the sender after preserving the evidence

Blocking may stop a particular number, but large collection operations often use multiple numbers or messaging providers. A database correction is therefore more effective than blocking alone.

Do not reply repeatedly to suspicious messages. Repeated engagement may confirm that the number is active without resolving the underlying data problem.

7. Escalate persistent or abusive contact

Use the regulator that supervises the original creditor.

Creditor or problem	Where to escalate	Practical starting point
Bank, credit card issuer, pawnshop, e-money issuer, or another BSP-supervised institution	Bangko Sentral ng Pilipinas	Complain first to the institution, then use the BSP Consumer Assistance Mechanism
Lending or financing company, including many online lending platforms	Securities and Exchange Commission	Submit a ticket through SEC iMessage
Inaccurate, excessive, or unauthorized use of your telephone number	National Privacy Commission	Follow the NPC complaint mechanics
Threats, impersonation, extortion, fraudulent payment instructions, or identity theft	Police, NBI, or appropriate cybercrime authorities	Preserve the original messages, payment account details, links, and call records
Reassigned-number or account-control issue	Your telecommunications provider	Request proof of account ownership, sender blocking assistance, or information about changing the number

The BSP requires consumers to raise the concern first with the supervised institution. Its current assistance page provides the BSP Online Buddy and an alternative Complaints, Inquiries and Requests form. Supporting documents should include the complaint sent to the institution, its reply if any, and evidence supporting the concern. (Bangko Sentral ng Pilipinas)

For an NPC case, the current procedure calls for a properly completed and notarized complaint form or verified complaint, together with evidence. Submission may be made personally, by registered mail, courier, or authorized electronic means. (National Privacy Commission)

Documents, likely costs, and timelines

Item	What to expect
Written correction request	No government filing fee; send by email and retain delivery or acknowledgment evidence
Proof of number ownership	Usually available from the telco application, billing statement, SIM records, or service contract
NPC exhaustion period	Generally 15 calendar days after the respondent receives your written privacy complaint
NPC formal complaint	Complaint or assisted form must ordinarily be notarized; notarization and current NPC filing or printing charges may apply
BSP escalation	The institution must first be given an opportunity to resolve the concern; BSP email submissions receive an automated acknowledgment
SEC complaint	File through SEC iMessage and preserve the ticket number and uploaded evidence
Resolution period	Varies according to the company, regulator, complexity, and whether the collector can identify the original creditor

People living abroad can usually begin by emailing the creditor, collector, or regulator and attaching screenshots and redacted proof of control over the number. If a formal Philippine proceeding requires a notarized document executed abroad, confirm whether the receiving agency will accept consular notarization, remote notarization where legally available, or a foreign notarization supported by an apostille.

Common mistakes to avoid

Paying a small amount just to stop the messages

Do not pay a debt that is not yours merely to end the calls. A payment can create confusion about whether you recognized or assumed the account and may expose your payment information to an unverified collector.

Saying “I will tell the borrower to pay”

That statement may encourage the collector to classify you as a reachable relative or contact person. State only that you are not the borrower, guarantor, or authorized representative.

Giving the collector the former user’s possible location

You are not required to investigate the borrower or provide information about neighbors, tenants, relatives, or former employees. Sharing unverified information may create privacy and safety problems.

Deleting everything immediately

Preserve evidence first. Screenshots, emails, call logs, and ticket numbers are important if you later need to show repeated contact after the company received your correction request.

Posting the collector’s messages publicly

Public posts may expose the alleged borrower’s name, loan details, account number, or other personal information. Send evidence privately to the company or regulator and redact unnecessary details when sharing documents.

Going only to the barangay

A barangay blotter can help document threats or disturbances, but the barangay generally cannot correct a lender’s database or impose regulatory sanctions on a bank, lending company, or collection agency. The creditor’s consumer-assistance unit, the BSP, SEC, or NPC is usually the more direct route for record correction and regulatory complaints.

When the situation may involve identity theft

Treat the matter more seriously when the messages use your name, address, birth date, ID details, employer, photograph, or email address—not merely your phone number.

Ask the creditor for a fraud investigation and state that you dispute the account. Request confirmation of:

The name recorded as borrower
The date the account was opened
The channel used to apply
The type of identity document presented
Whether facial verification or an electronic signature was used
Whether your number was used to receive an OTP
Whether the account was reported to a credit-information system

The creditor may redact documents to protect other persons or its security controls, but it should investigate a credible identity-theft claim. Change passwords on accounts connected to the number, secure your email and e-wallets, and do not disclose OTPs to anyone claiming to “clear” the loan.

What if the collector threatens court action or arrest?

A private demand letter, text message, or collection call is not a court judgment. An ordinary unpaid civil debt does not become your obligation merely because a collector threatens to sue the former user.

A genuine court case involves court-issued documents and service of summons under Rule 14 of the Rules of Civil Procedure. The Supreme Court’s electronic-filing guidelines continue to treat summons separately from ordinary emailed court documents. (Supreme Court of the Philippines)

If a sheriff or process server visits your address looking for the former user:

Do not sign using the former user’s name.
State truthfully that the person does not live there or is unknown to you.
Show identification only as reasonably necessary to establish that you are a different person.
Do not accept responsibility for delivering the papers unless you understand why they are being left with you.
Record the court, branch, case number, and process server’s name.

Threats of physical harm, public shaming, false criminal accusations, or publication of your information may raise separate privacy, civil, administrative, or criminal issues. Articles 19, 20, 21, and 26 of the Civil Code require honesty and good faith and recognize remedies for conduct that unlawfully damages another person’s dignity, privacy, or peace of mind. (Lawphil)

Frequently Asked Questions

Can a collection agency legally keep calling me after I say it is a wrong number?

An initial call based on an apparently valid record may be explainable. Continued calls after a clear written correction request are more difficult to justify, especially when the company makes no reasonable effort to verify or correct the number. Document every contact after your notice.

Does SIM registration prove that I am not the borrower?

It can help prove that you currently control the number, but it does not by itself establish who used the number when the loan was obtained. Combine it with the acquisition or activation date, billing records, and other evidence where available.

Am I liable because I was listed as an emergency contact or character reference?

No. A character reference does not become a guarantor automatically. A guarantor must expressly bind themselves to answer for the borrower’s obligation, and the NPC requires separate consent in loan-related data processing. (National Privacy Commission)

Can the collection agency reveal the former subscriber’s loan details to me?

It should disclose only what is reasonably necessary to explain and correct the use of your number. You may ask about the source and processing of your number, but you are not entitled to unrestricted access to another person’s financial records.

Will the former user’s debt affect my credit record?

A message sent to your number does not itself create a debt or judgment against you. The risk is different if the account also uses your name or identity details. In that situation, dispute the account as possible identity theft rather than treating it as a simple wrong-number problem.

Should I change my mobile number?

Changing the number may be a practical last resort when several unrelated creditors repeatedly contact a heavily recycled number. It can also disrupt banking, e-wallet, government, employment, and authentication accounts, so first attempt database correction and document the problem with your telco.

Can I demand deletion of every record containing the number?

You may request correction, blocking, or removal of the number from collection and contact systems when its association with you is inaccurate. The company may still retain legitimate historical records needed for regulatory compliance, fraud prevention, or legal claims, but it should not continue treating your number as a valid way to reach the debtor.

Do I need a lawyer to send the correction request?

No special legal format is required for the initial notice. A clear email identifying the number, denying any relationship to the debt, requesting correction and cessation of contact, and invoking your privacy rights is usually enough to begin the process.

What if the collector refuses to identify the creditor?

Do not send money or personal documents. Save the message, verify the sender independently, and treat requests for payment or sensitive information as potentially fraudulent. A legitimate collector should be able to identify the entity on whose behalf it is acting and provide an official complaint channel.
