If you're searching for how to verify a business name with the DTI or checking whether your preferred name is available before launching a sole proprietorship in the Philippines, this guide walks you through exactly what you need to know and do.

Many Filipinos and foreigners who want to operate legitimately under a trade name (instead of their personal name) run into the same practical questions: Is the name already taken? How do I confirm a registration is real and active? What does the process actually involve in 2026, and what happens if I skip it? DTI business name verification and registration provide the legal foundation for using that name across receipts, signs, contracts, bank accounts, and online platforms.

What DTI Business Name Registration Actually Does

A Business Name (BN) is any name other than your true legal name that you use in connection with your business — on receipts, invoices, signage, websites, or marketing materials. Registering it with the Department of Trade and Industry (DTI) gives your sole proprietorship an official legal identity and grants you the right to use that name within your chosen territorial scope.

This is different from:

SEC registration (required for partnerships and corporations)
Mayor’s or business permit from your local government unit (needed to actually operate)
BIR registration (for tax purposes and official receipts)

Without a DTI-registered business name, you cannot legally use a trade name. Many banks, e-commerce platforms (Shopee, Lazada, etc.), clients, and government agencies will ask for your DTI Certificate of Business Name Registration as proof of legitimacy.

Legal Basis Under Philippine Law

The primary law is Republic Act No. 3883, as amended, known as the Business Name Law. It requires any person doing business under a name other than their true name to register it with the DTI (formerly the Bureau of Commerce). The Revised Implementing Rules and Regulations of RA 3883 govern the current online system and detailed rules on what names are acceptable.

Non-compliance can expose you to administrative sanctions and practical problems when trying to open bank accounts, issue official receipts, or enforce contracts. The DTI’s Business Name Registration System (BNRS) Next Gen portal handles applications, renewals, and public verification today.

How to Verify a Business Name Registration

You can check whether a business name is already registered and its current status through DTI’s free public search tool. This is useful when vetting potential partners, suppliers, or competitors, or when confirming your own registration details.

Step-by-step verification process:

Go to the official Business Name Search page on the BNRS portal.
Enter the exact business name (including spacing, punctuation, and capitalization).
Submit the search.

The system is limited to exact-name matches only — random or partial searches are not allowed. When results appear, you will typically see key details such as the registration number, owner name (in many cases), date issued, expiry date, status (Active, Expired, or Cancelled), and territorial scope.

You can also scan the QR code printed on a physical or digital Certificate of Business Name Registration — it links directly to the official record. For formal or certified verification (e.g., for court or major transactions), visit a DTI office or Negosyo Center and request a certified true copy using the appropriate form and paying the prescribed fee.

Step-by-Step Guide to Registering Your Business Name (Includes Availability Check)

The same portal handles both availability checking and full registration. The process is fully online for most Filipino applicants.

Visit bnrs.dti.gov.ph/registration and agree to the terms and conditions under the Revised IRR of RA 3883.
Fill in your personal information as the owner (complete name, address, valid government-issued ID details, email, and mobile number).
Select your territorial scope and enter your proposed Dominant Name (the main identifying words) plus a Business Name Descriptor (keywords describing the nature of your business, drawn from Philippine Standard Industrial Classification or PSIC descriptors).
Click “Check Name Availability”. The system automatically verifies whether the exact combination is available within your chosen scope.
If available, note your Reference Code and continue filling business address, nature of business, and other required details.
Review everything, agree to the Undertaking, and proceed to payment.
Pay the registration fee within 7 calendar days using GCash, PayMaya, credit/debit card, Landbank Link.Biz, or over-the-counter options (7-Eleven, Bayad Center). Late payment causes the application to be abandoned.
Once payment is confirmed, download and print your Certificate of Business Name Registration. It is also sent to your registered email.

The entire online process is usually quick when your preferred name is available. Keep your Reference Code safe — you will need it for renewals, transaction inquiries, or cancellations.

Choosing the Right Territorial Scope

Your choice determines both the fee and the geographic extent of name protection (where you can locate branches or primarily use the name without conflict).

Territorial Scope	Registration Fee	Documentary Stamp Tax	Total (approx.)	Best suited for	Level of protection
Barangay	₱200	₱30	₱230	Very small neighborhood businesses	Limited to that barangay
City/Municipality	₱500	₱30	₱530	Most small local businesses	Within one city or municipality
Regional	₱1,000	₱30	₱1,030	Businesses operating across a region	Entire region
National	₱2,000	₱30	₱2,030	Businesses planning nationwide reach	Whole country

Wider scope gives stronger protection but costs more and requires the name to be available across that broader area. Changing scope later is treated as a new application with a new validity period.

Requirements, Documents, and Special Rules for Foreigners

Filipino citizens (at least 18 years old) can complete the entire process online with a valid government-issued ID.

Foreign nationals, recognized refugees, and stateless persons must generally submit supporting documents at a physical DTI office before or during processing. Key additional requirements include authorization under Republic Act No. 7042 (Foreign Investments Act) — typically a Certificate of Registration of Sole Proprietorship or Certificate of Authority to Engage in Business. Refugees need written recognition from the DOJ’s Refugee and Stateless Persons Protection Unit. A resident agent appointment and proof of inward remittance or bank deposit are often required. These extra steps add time and complexity compared with the fully online Filipino process.

A representative can file on your behalf with a signed authorization letter and valid IDs from both parties.

Fees, Payment, and Validity Period

Fees are fixed by territorial scope (see table above) plus ₱30 Documentary Stamp Tax. An additional 50% surcharge applies for late filing. Payment must be completed within 7 calendar days or the application is nullified.

The Certificate of Business Name Registration is valid for five (5) years from the date of registration. Renewal follows a similar online process and should be done before expiry to avoid losing rights to the name.

Common Pitfalls and Real-Life Scenarios

Many people encounter these issues:

The exact name combination is unavailable. The system rejects purely generic names, those that are misleading, unlawful, scandalous, or already registered as trademarks/trade names. It also rejects names using “company,” “corporation,” “incorporated,” or “cooperative” (reserved for SEC or CDA entities).
Missing the 7-day payment window.
Choosing too narrow a scope and later needing to expand (which requires a new application).
Foreign applicants underestimating documentary requirements and facing delays.
Using an unregistered name on official documents or platforms, leading to rejected transactions or compliance issues.

Real scenarios include a freelancer who registers “Maria Santos Virtual Assistance Services” to issue official receipts to clients; an OFW returning home who wants a sari-sari store or online shop under a catchy name; a foreign spouse opening a small café and needing to navigate extra DTI and immigration steps; or someone checking whether a supplier’s claimed DTI registration is active before signing a contract.

What to Do After You Receive Your DTI Certificate

Your DTI registration is only the first step toward full legal operation. Next, obtain your Mayor’s/Business Permit from the city or municipal hall (most LGUs require the DTI certificate). Register with the BIR for a Certificate of Registration, books of accounts, and authority to print official receipts. If you will have employees, register with SSS, PhilHealth, and Pag-IBIG. Certain industries require additional licenses (FDA for food, etc.). Banks and lenders almost always ask for both DTI and Mayor’s permits.

Frequently Asked Questions

How do I check if a business name is already registered with DTI?
Visit the official BNRS search tool at bnrs.dti.gov.ph/search and enter the exact name. Results show registration status, validity, territorial scope, and other key details.

Is DTI business name registration mandatory?
Yes, if you operate under any name other than your true legal name, per RA 3883. Using an unregistered trade name exposes you to compliance risks.

How much does DTI business name registration cost?
It depends on territorial scope: ₱200 (barangay), ₱500 (city/municipality), ₱1,000 (regional), or ₱2,000 (national), plus ₱30 documentary stamp tax.

Can foreigners register a business name in the Philippines?
Yes, if they are authorized under RA 7042 and meet additional documentary requirements, which usually involve submission at a DTI office.

What happens if my preferred business name is already taken?
You must choose a different dominant name or descriptor combination. The system will not allow registration of an identical or conflicting name within the same territorial scope.

How long is a DTI business name registration valid?
Five years from the date of registration. Renew before expiry through the BNRS portal.

Do I still need a mayor’s permit after getting DTI registration?
Yes. DTI gives you the legal business name identity; the mayor’s permit authorizes actual operations at your location.

Can I correct mistakes after submitting my DTI application?
Minor typographical errors in a new registration can sometimes be corrected by emailing the helpdesk with your ID. Major changes usually require a new application or an in-person visit to a DTI office.

Is the public search tool limited in any way?
Yes. It only accepts exact name matches. It does not support fuzzy or broad searches.

Where can I get help if I encounter problems during online registration?
Use the BNRS helpdesk email (bnrshelpdesk@dtiphmail.dti.gov.ph), text/viber line, or visit your nearest DTI office or Negosyo Center.
