Quick answer

Verify a business against the registry for its legal form:

Sole proprietorship: Search the exact business name through the DTI’s official Business Name Registration System (BNRS).
Corporation, One Person Corporation, partnership, or Philippine-licensed foreign corporation: Search through the SEC’s official Check with SEC service. For copies of filed documents, use SEC eSEARCH.
Cooperative: Check with the Cooperative Development Authority, not the SEC or DTI. The CDA issues the cooperative’s certificate of registration through its registration service.

A matching search result is only the first check. Compare the official record with the certificate, the person claiming authority to act, the business address, and any additional permits or licenses required for the transaction. Registration alone does not prove that a business is trustworthy, financially sound, tax-compliant, authorized for a regulated activity, or safe to pay or invest in.

First determine whether to check the SEC or DTI

Claimed business form	Primary registry	Document normally expected
Sole proprietorship	DTI	Certificate of Business Name Registration
One Person Corporation	SEC	Certificate of Incorporation
Stock or non-stock corporation	SEC	Certificate of Incorporation
Partnership	SEC	Certificate of Recording or registration document issued by the SEC
Foreign corporation doing business in the Philippines	SEC	License to Do Business
Cooperative	CDA	Certificate of Registration

Do not decide based only on the brand name. A shop called “ABC Trading” might be a sole proprietorship, while “ABC Trading Inc.” should ordinarily point to a corporation. Ask for the exact registered name and registration number when the legal form is unclear.

An individual can be the sole stockholder of an SEC-registered One Person Corporation. Therefore, “one owner” does not necessarily mean DTI registration.

How to verify an SEC registration

1. Obtain the exact legal details

Ask the business for:

Its complete SEC-registered name, including “Inc.,” “Corp.,” “OPC,” or the appropriate partnership designation
SEC registration number
Date of registration
Copy of its Certificate of Incorporation, Certificate of Recording, or License to Do Business
Registered principal-office address
Latest General Information Sheet, when relevant
Proof of any secondary license or authority required for its activity

A social-media name, product name, website domain, or storefront name may not be the entity’s legal name.

2. Search the official SEC database

Open Check with SEC from the SEC’s official domain. Search using the exact company name or SEC number supported by the portal.

Compare the result with the documents supplied to you. Check, as available:

Exact registered name
SEC number
Entity type
Registration date
Registration status
Principal-office information
Any listed secondary licenses

A close or similar name is not enough. Confirm that the SEC number and other identifying details refer to the same entity—not another company with a similar name.

3. Read the status carefully

A record marked registered confirms that an SEC record exists. It does not necessarily establish that:

All annual reports are current
The corporation remains in good standing for every purpose
The person contacting you is an authorized officer or representative
The company holds every license needed for its business
A specific investment, loan, franchise, property, or product is lawful
The company has no pending regulatory, civil, or criminal issue

A suspended, revoked, expired, or otherwise restricted status requires clarification directly from the SEC and, for an important transaction, advice from a Philippine lawyer. Do not rely solely on the company’s explanation.

Do not reject a corporation merely because its certificate is old. Under Section 11 of the Revised Corporation Code, a corporation generally has perpetual existence unless its articles provide otherwise, subject to the law’s transitional rules and lawful dissolution, suspension, or revocation. The current SEC record and the entity’s governing documents matter more than the certificate’s age.

4. Inspect the actual SEC documents

For higher-value or higher-risk transactions, obtain records through SEC eSEARCH, the SEC’s channel for accessing documents filed with the Commission. Depending on what is relevant, review:

Certificate of Incorporation or Recording
Articles of Incorporation or Partnership
Amendments to the articles
Latest available General Information Sheet
Latest available financial statements
Secondary license or certificate of authority
Other material filings affecting the transaction

Check whether the business purpose covers the activity being offered. Compare the registered address and named officers with the contract, invoice, website, email signature, and payment instructions.

A General Information Sheet reflects information reported for a particular filing period. It should not be treated as conclusive proof that a person remains authorized today. For a contract, sale of property, loan, or other substantial transaction, request a current secretary’s certificate, board resolution, partnership authority, or special power of attorney appropriate to the transaction.

5. Authenticate the certificate

Newer SEC electronic-registration processes issue digitally signed certificates. The SEC states that certificates issued through its ZERO processing system have the same legal validity as original certificates and use system-integrated QR codes and SEC digital signatures. See the official SEC eSPARC guidance and eSAP authentication portal.

When checking an electronic certificate:

Use the original PDF, not just a screenshot or cropped image.
Inspect the digital-signature information in a proper PDF reader.
Scan the QR code and verify that it leads to an official SEC-controlled domain.
If the document supplies a validation code for the SEC Check App, use the official SEC Check App.
Compare the validated information with the name and SEC number printed on the document.

A name reservation, application reference number, payment assessment, or pending eSPARC application is not proof that registration was completed. Under Section 18 of the Revised Corporation Code, corporate existence begins when the SEC issues the certificate of incorporation.

6. Escalate unclear SEC results

If the company does not appear, multiple records appear, information is missing, or the status cannot be interpreted confidently, submit an inquiry through the SEC’s official iMessage ticketing system. The SEC’s published iMessage services include concerns involving companies not found in its system, multiple company records, unavailable statuses, missing information, and requests for certain certifications or authenticated copies.

For a transaction requiring formal proof, ask the SEC which certification or authenticated record is appropriate instead of treating an ordinary search-page screenshot as conclusive evidence.

How to verify a DTI business-name registration

1. Use the exact-name BNRS search

Open the official DTI BNRS Business Name Search. Enter the complete business name exactly as presented and complete the portal’s verification step.

The BNRS expressly limits public verification to an exact-name search. If the first search returns nothing, check the certificate or invoice for:

Spelling
Spacing
Punctuation
Abbreviations
Words describing the business activity
Singular or plural forms

Do not substitute a broad or “sounds like” search for an exact match.

2. Compare the result with the DTI certificate

A DTI Certificate of Business Name Registration should be checked for:

Approved business name
Name of the registered owner
Business Name Number
Territorial scope
Registered business or purpose information
Date of issuance
Validity period

The person operating a sole proprietorship is legally important. A DTI-registered business name is not a separate corporation. The Supreme Court has repeatedly explained that a sole proprietorship has no juridical personality separate from its owner; the owner is personally connected to the business’s rights and obligations. See, for example, Excellent Quality Apparel, Inc. v. Win Multi-Rich Builders, Inc., G.R. No. 175048.

Accordingly, verify the proprietor’s identity when entering a significant transaction. A certificate belonging to one person should not be used by another person as though the business had been transferred.

3. Check whether the registration is still valid

Under DTI Department Administrative Order No. 18-07, the Revised Rules implementing the Business Name Law, a Certificate of Business Name Registration is valid for five years from issuance.

The rules provide these renewal periods:

Renewal may be filed as early as 180 calendar days before expiration.
Regular renewal may be filed within 90 calendar days after expiration.
A further 90-calendar-day grace period is available after the regular filing period, subject to a surcharge equal to 50% of the registration fee.
After the grace period, renewal is no longer accepted; the application is treated as a new registration, and the expired name may become available to another applicant.

Check the dates shown on the certificate and the current BNRS result. Do not accept an expired certificate simply because the business has used the name for many years.

4. Use the appropriate BNRS service for stronger proof

The BNRS services page provides separate options for public name search, transaction inquiry, and requests for certification.

Business Name Search is the basic public check.
Transaction Inquiry is used to retrieve or continue a transaction using its reference code.
Request Certification is the better route when a formal DTI certification is needed for due diligence, litigation, banking, procurement, or another official purpose.

A transaction reference code by itself is not proof that the business-name application was approved.

What SEC or DTI registration does not prove

It is not a Mayor’s Permit

DTI’s own BNRS FAQ explains that business-name registration alone is not authority to operate. A business generally needs the applicable business or Mayor’s Permit from the city or municipality where it operates.

Confirm the permit with the issuing LGU’s Business Permits and Licensing Office. Check the business name, owner or entity, address, line of business, permit number, validity year, and any conditions.

It is not complete proof of BIR registration

Ask for the business’s BIR Certificate of Registration or electronic Certificate of Registration and check that its registered name, TIN, address, and tax types are consistent with the other documents.

BIR Revenue Memorandum Circular No. 38-2026 announced QR codes for BIR CORs and eCORs to enable verification of authenticity and the validity of a taxpayer’s business registration. Use the QR code in accordance with the official BIR circular, but still compare the resulting record with the business you are dealing with.

It is not a license for every regulated activity

Depending on the business, additional authority may be required from the SEC or another regulator. Examples may include lending, financing, investment solicitation, banking, insurance, securities dealing, recruitment, education, health services, food or drug activities, construction, transportation, or professional practice.

This distinction is especially important for investments. The SEC has expressly warned that corporate registration grants juridical personality but does not, by itself, authorize the public offering of securities, investment-taking, or activities requiring a secondary license. Review the SEC record, applicable secondary license, and current SEC advisories before sending money.

It is not trademark registration

SEC or DTI registration should not be treated as proof that the business owns a trademark. Trademark protection is administered by the Intellectual Property Office of the Philippines. IPOPHL explains the separate role of trademark registration in protecting brand identity in its Trademark FAQ.

A practical due-diligence checklist

Before paying, signing, investing, supplying goods on credit, or releasing confidential information:

Identify the claimed legal form and correct registry.
Obtain the exact registered name and registration number.
Conduct the official SEC or DTI search yourself.
Compare the registry result with the original certificate.
Match the proprietor, officers, address, and business activity.
Check the certificate’s QR code, validation code, or digital signature when available.
Review current SEC filings or request formal certification when the stakes justify it.
Verify the current Mayor’s Permit and BIR registration.
Check secondary or industry-specific licenses.
Confirm that the signatory has current authority for the particular transaction.
Verify payment instructions independently. Be cautious if payment is demanded to an unrelated personal account.
Search current official enforcement notices or advisories from the relevant regulator.

Evidence to preserve

Keep an organized record of the verification:

Original certificate PDFs and documents received
Complete screenshots or PDF printouts of registry results
Full URLs and the date and time of each search
SEC or DTI ticket numbers and agency replies
Contracts, proposals, invoices, official receipts, and payment instructions
Emails with full headers, text messages, and chat exports
Advertisements and representations about registration or licensing
Names, IDs, and authority documents of people acting for the business
Bank or e-wallet account details supplied for payment

Preserve original files. Forwarding, compressing, or repeatedly converting a PDF may remove digital-signature information or metadata useful for authentication.

Common mistakes

Searching the DTI for a corporation or the SEC for a sole proprietorship
Searching only the brand, Facebook-page name, or shortened name
Treating a similar name as an exact match
Accepting a screenshot without checking the official portal
Confusing an application, reservation, or payment receipt with an issued certificate
Ignoring an expired DTI certificate
Assuming an old SEC certificate has expired without checking the corporate term and current status
Assuming “SEC registered” means authorized to solicit investments
Assuming the latest available GIS proves present authority to sign
Failing to match the registered owner or entity with the recipient of payment
Treating DTI or SEC registration as a substitute for BIR, LGU, or industry permits
Assuming business-name registration is the same as trademark ownership

When help is urgent

Pause the transaction and obtain direct agency confirmation or legal advice if:

The business cannot provide its exact registered name or number.
The certificate and official search result do not match.
The SEC record is suspended, revoked, restricted, or unclear.
The DTI certificate is expired or names a different proprietor.
A purported certificate’s QR code or validation code fails.
The seller or promoter refuses to provide licenses relevant to the activity.
An investment promoter relies only on basic SEC incorporation.
Payment is requested through an unrelated person or frequently changing accounts.
Documents appear altered, cropped, inconsistent, or recently recreated.
The transaction involves substantial money, shares, real property, a franchise, a long-term loan, or personal guarantees.

For SEC records and suspected investment-related issues, use SEC iMessage. For a consumer complaint involving goods or services, the DTI operates the Consumer CARe system. If money has already been sent in suspected fraud, contact the bank or payment provider immediately and seek advice on reporting the matter to the appropriate authorities.

Frequently asked questions

Does a result in Check with SEC prove that the company is legitimate?

It proves that a corresponding SEC record exists, subject to the accuracy and currency of the database. It does not guarantee honesty, financial capacity, regulatory compliance, or authority for a specific transaction.

Does a DTI certificate mean the business is a company separate from its owner?

No. DTI business-name registration is for a sole proprietorship. The proprietorship has no legal personality separate from its owner.

Is a DTI registration valid forever?

No. It is valid for five years from issuance and must be renewed within the periods prescribed by DTI rules.

Does an SEC Certificate of Incorporation have to be renewed every year?

The certificate is not an annual business permit. Corporations generally have perpetual existence unless their articles provide otherwise, but they remain subject to reportorial duties and possible suspension, revocation, or dissolution. Verify the current SEC status and relevant filings.

What if the business does not appear in an online search?

Check the exact spelling and the correct registry. The entity may also be recorded under another legal name, have a legacy or incomplete record, or be registered with another regulator. Do not conclude that it is registered based on its own explanation; contact the SEC through iMessage or the DTI through BNRS official support.

Is a registration number alone enough?

No. Numbers can be copied from another business. Match the number with the exact name, entity type, owner or officers, address, certificate, and official registry result.

Can a corporation use a trade or brand name different from its SEC name?

It may use a trade or brand name subject to applicable rules, but contracts, invoices, permits, and payment arrangements should clearly identify the legal entity behind that name. Verify the SEC-registered entity, not only the brand.

Should I ask for certified records?

For ordinary low-risk purchases, an official online check may be sufficient. For litigation, procurement, banking, investments, credit, property, corporate acquisitions, or other substantial transactions, obtain authenticated or formally certified records appropriate to the purpose.
