Quick answer

Use the registry that matches the business’s legal form:

Search the DTI Business Name Registration System (BNRS) for a sole proprietorship operating under a business name.
Search the SEC’s Check with SEC service for a corporation, One Person Corporation, partnership, or foreign corporation licensed to do business in the Philippines.
Search the Cooperative Development Authority—not DTI or SEC—for a cooperative.

Ask for the exact registered name and registration number before searching. Then compare the official result with the certificate, contract, invoice, address, owner or entity receiving payment, and any required permit or secondary licence.

A registry match confirms only the registration reflected in that agency’s records. It does not by itself prove that the seller is genuine, that the registration remains in good standing, that the person contacting you represents the registered business, or that the business may lawfully conduct every activity it advertises.

Choose the correct registry

Claimed legal form	Primary registry	What the registration generally establishes
Sole proprietorship using a business name	DTI BNRS	Registration of the business name and its proprietor
Corporation, including an OPC or non-stock corporation	SEC	Corporate existence following issuance of the certificate of incorporation
Partnership	SEC	Recording or registration of the partnership
Foreign corporation doing business in the Philippines	SEC	Licence to transact business in the Philippines
Cooperative	Cooperative Development Authority	Cooperative registration

DTI’s online system is specifically for sole-proprietor business names. A DTI-registered business name does not create a corporation or a separate legal personality. The proprietor remains the person operating the business.

Under the Revised Corporation Code, a private corporation acquires corporate existence and juridical personality when the SEC issues its certificate of incorporation. A name reservation, application reference number, payment receipt, draft articles, or pending application is not equivalent to an issued certificate.

Under Act No. 3883, as amended, a person using a business name other than the person’s true name must register that name. A sole proprietor trading only under their true name may therefore have no DTI business-name record, although tax, local-permit, and sector-specific requirements may still apply.

Information to obtain before searching

Ask the business for:

Its complete legal or registered name, including “Inc.,” “Corp.,” “Corporation,” “OPC,” or other suffix.
Its SEC registration number or DTI Business Name number.
A clear copy of its certificate of incorporation, partnership registration, licence to do business, or DTI Certificate of Business Name Registration.
Its registered address and current operating address.
The name of the contracting party and the person or entity that will receive payment.
Its latest mayor’s or business permit and BIR Certificate of Registration when relevant.
Any secondary licence, certificate of authority, accreditation, franchise, or professional licence required for the advertised activity.

Search the legal name—not merely a brand, store name, social-media handle, mobile application name, or website domain. A brand may be owned by a differently named corporation, while a scammer may copy the name and documents of a real business.

How to check a DTI business name

1. Use the official BNRS search

Open the DTI Business Name Search. The portal limits verification to an exact-name search, so enter the full registered name shown on the certificate. Include its distinctive portion and business descriptor, and try the certificate’s exact punctuation and spacing if the first attempt produces no result.

Do not use an advertisement’s shortened name if the certificate shows a longer registered name.

2. Compare the result with the certificate

Review every field displayed and compare it with the document supplied by the business. Depending on the available record, relevant details may include:

Exact business name
Business Name number
Registered proprietor
Date of registration or expiration
Territorial scope
Registered business address or other identifying information

A partial name match is insufficient. The registered proprietor is especially important because the business name belongs to that proprietor.

In Villanueva v. Coca-Cola Bottlers Philippines, Inc., the Supreme Court explained that the Business Name Law protects people dealing with businesses operated under names that obscure their true owners. In the circumstances of that case, the Court held that the public could rely on the person identified as the registered proprietor. The decision should not be read as authenticating every person who merely displays a copied DTI certificate. See G.R. No. 264746, August 7, 2024.

3. Check the certificate’s validity date

Under DTI’s current Revised Implementing Rules and Regulations of the Business Name Law, a Certificate of Business Name Registration is valid for five years from issuance.

DTI states that renewal may be filed:

As early as 180 calendar days before expiration;
During the regular filing period, up to 90 calendar days after expiration; or
During the late or grace period, from 91 to 180 calendar days after expiration, subject to a surcharge equal to 50% of the registration fee.

A renewal window does not change the expiration date printed on the certificate. If the certificate has expired, ask for proof of completed renewal and confirm the updated record instead of accepting an assurance that renewal is “being processed.” Current renewal guidance appears in the DTI BNRS FAQ.

4. Escalate an uncertain result

If the exact name still produces no result, check for spelling errors, an expired or changed business name, and whether the enterprise is actually a corporation or cooperative. For an agency-issued confirmation, use the BNRS Request Certification service or contact DTI through the channels published on the BNRS portal.

Do not rely on a transaction reference code alone. The BNRS Transaction Inquiry is intended to track a particular transaction using its reference code; it is not a substitute for verifying the issued registration.

How to check an SEC registration

1. Search the official SEC database

Go directly to Check with SEC. Search using the exact corporate or partnership name or the SEC registration number.

Beware of imitation websites. Confirm that the address ends in sec.gov.ph, and do not enter personal information on a look-alike domain.

2. Match the entity, not just the name

Compare the official record with the certificate and proposed transaction. Check, as available:

Complete registered name
SEC registration number
Entity or company type
Registration date
Registered address
Primary registration status
Any displayed secondary licence or certificate of authority
Available reportorial or filing information

A similar name may belong to a different entity. The SEC registration number is a stronger identifier, but it must still correspond to the exact name and documents.

Treat a suspended, revoked, delinquent, dissolved, expired, or otherwise restricted status as a serious warning. Do not guess what a status label permits. Ask the SEC for written clarification through its iMessage ticketing system before paying, investing, lending money, or entering a substantial contract.

3. Inspect supporting corporate records

For higher-risk transactions, examine available filings through the SEC’s eSEARCH service and request appropriate official copies where necessary. Useful records can include:

Certificate of incorporation or partnership registration
Articles of incorporation or partnership
Latest General Information Sheet
Recent audited financial statements, when required and available
Certificates covering amendments, changes of name, merger, revival, dissolution, or other material events
Secondary licence or certificate of authority for a regulated activity

A General Information Sheet or secretary’s certificate supplied by the company may help identify officers and authorised representatives, but it should be checked for its filing or issuance date. For an important contract, also request current proof that the signatory is authorised, such as an appropriate board resolution or secretary’s certificate.

Digitally issued SEC certificates can have the same legal validity as their paper counterparts. Preserve the original electronic file so its digital signature and other security features can be examined; do not rely solely on a screenshot or printed image.

Check authority to conduct the advertised activity

Primary registration and operating authority are different matters. Depending on the business, verify the current LGU permit, BIR registration, and licence from the responsible regulator.

Examples include:

A lending company must be organised as a corporation and have a valid SEC authority to operate under the Lending Company Regulation Act. SEC incorporation alone is not enough.
An entity offering investments may need an effective registration statement for the securities and appropriate authority for the persons selling them, subject to statutory exemptions. See the Securities Regulation Code.
Banks and certain financial institutions require Bangko Sentral ng Pilipinas authority.
Insurance businesses and intermediaries may require Insurance Commission authority.
Recruitment agencies, schools, health facilities, real-estate practitioners, contractors, travel-related businesses, and other regulated activities may require separate government licences or accreditation.
A business selling regulated products may need product-specific approvals or certifications.

Ask for the specific licence number and verify it with the issuing regulator. Do not accept a broad statement that “SEC registered” or “DTI registered” authorises all advertised services.

What registration does not prove

Even a genuine, current registration does not establish that:

The person messaging you is connected with the registered business;
The bank or e-wallet account belongs to the business or an authorised collector;
The business is financially sound or able to perform its promises;
An investment, franchise, loan, product, or service has government approval;
The business has no complaints, cases, unpaid obligations, or regulatory violations;
A product is safe, authentic, or properly certified;
A transaction is fair or free from fraud.

Confirm contact details independently. Use the telephone number, email address, or website found in reliable official records or documents—not only the contact information supplied in the suspicious message. If payment is requested to a personal account, obtain a written explanation and independently confirm the payee’s authority. A personal account is not conclusive proof of fraud, particularly for a sole proprietor, but a mismatch requires careful verification.

Practical verification checklist

Before paying or signing:

Match the exact legal name in the registry, certificate, contract, invoice, and payment instructions.
Match the SEC or DTI registration number across all documents.
Confirm the current status and validity date.
Verify the proprietor for a DTI-registered sole proprietorship.
Verify the corporation or partnership’s registered address and relevant officers.
Check the latest LGU business permit for the actual establishment or branch.
Check BIR registration and the business’s ability to issue the proper invoice.
Verify every required secondary licence directly with the issuing regulator.
Call the business through an independently obtained number.
For a large transaction, request recent filings and proof of the signatory’s authority.
Use traceable payment methods and insist on a written contract and proper invoice.

Evidence to preserve

Keep complete, unedited copies of:

The certificate and original electronic file received;
Search results showing the URL and date checked;
The exact search term and registration number used;
Advertisements, product listings, websites, and social-media profiles;
Emails, text messages, chat exports, and call details;
Contracts, quotations, invoices, delivery records, and warranties;
Bank or e-wallet account names, transaction references, and payment receipts;
Names, numbers, and representations made by agents or salespersons.

Preserve original files and messages rather than only cropped screenshots. Record the date and time of each verification. Do not publicly post unredacted identification documents, home addresses, banking information, or other sensitive personal data.

Common mistakes

Searching DTI for a corporation or SEC for a sole proprietorship.
Searching only a brand or social-media page name.
Treating a similar name as an exact match.
Accepting an application reference, name reservation, or payment receipt as proof of completed registration.
Looking only at an old certificate without checking current status.
Assuming registration is the same as a mayor’s permit, BIR registration, or sector licence.
Believing that a real registration proves the contacting person’s identity.
Failing to compare the registered owner or entity with the payee.
Relying on a QR code or screenshot without opening the official government record.
Sending money because the seller creates urgency or discourages independent verification.

When help is urgent

Act immediately if money has already been sent, account credentials or one-time passwords were disclosed, the business appears to be impersonating a registered entity, or an unlicensed investment or lending operation is involved.

Contact the bank, card issuer, or e-wallet provider at once and ask whether the transaction can be held, recalled, traced, or flagged. Preserve evidence before accounts or posts disappear.

Depending on the issue:

Send corporate-registration, lending, financing, or investment concerns to the SEC through iMessage.
File an eligible consumer complaint through the DTI Consumer CARe System.
Report suspected online fraud through the NBI Online Complaint facility or seek assistance from the appropriate law-enforcement office.
Consult a Philippine lawyer promptly if a large payment, investment, continuing contract, threatened deadline, identity theft, or possible criminal conduct is involved.

Frequently asked questions

Is an online SEC or DTI search enough for a major transaction?

No. It is a useful first check. For a substantial contract, investment, franchise, loan, or property transaction, obtain current official records, verify the signatory’s authority and required licences, and consider professional due diligence.

Does DTI registration mean the business is legitimate?

It confirms the business-name registration reflected in DTI records. It does not guarantee the transaction, product, seller’s identity, financial capacity, or compliance with other permits and laws.

Why can I not find the business in BNRS?

BNRS requires an exact-name search. Check spelling, punctuation, descriptors, and the certificate itself. The business may also be a corporation, partnership, cooperative, renamed entity, or sole proprietor trading under a true name. An unresolved absence should be confirmed with the appropriate agency.

Can a corporation have both an SEC name and a different brand?

Yes. A corporation may market under a brand or trade name. Ask which SEC-registered entity owns or operates the brand and make sure that entity—not merely the brand—is identified in the contract and payment documents.

Does an SEC registration expire every five years like a DTI business name?

Generally, no. Corporations ordinarily have perpetual existence unless their articles provide otherwise, but they may later become delinquent, suspended, revoked, dissolved, or otherwise restricted. Always check the current SEC status rather than relying on the age of the certificate.

Is a BIR Certificate of Registration a substitute for SEC or DTI verification?

No. BIR registration concerns tax administration. It should be cross-checked with, not substituted for, the appropriate SEC, DTI, CDA, local-government, and sector-specific records.

What if the registration is real but the payment account has another name?

Pause the transaction. Independently contact the registered business and request written proof that the payee is authorised. For a sole proprietor, the personal name may properly appear; for a corporation, payment to an unrelated personal account warrants heightened scrutiny.
