I. Why “proper registration” matters

In the Philippines, “registered” can mean different things depending on what you’re checking:

Name registration (the right to use a name)
Entity registration (legal existence of a business entity)
Business permits and tax registration (authority to operate and pay taxes)
Regulatory licenses (authority to operate a regulated activity)

A business may have a registered business name but still be unregistered as a corporation, or may be SEC-registered but not authorized to operate in a specific city/municipality without a mayor’s permit, or may be operating without BIR registration, which is a common compliance issue.

Your goal when verifying registration is to match the business’s claimed identity (name, owners/directors, address, tax IDs, registration numbers, line of business) against official registrations and current operating authority.

II. Know what kind of “business” you are dealing with

Start by identifying the business’s legal form. The correct agency and records depend on this:

A. Sole proprietorship (individual owner)

Registered with DTI for the business name
Still needs LGU permits and BIR registration

B. Partnership / Corporation (domestic)

Registered with the SEC
Still needs LGU permits and BIR registration

C. One Person Corporation (OPC)

Registered with the SEC
Still needs LGU permits and BIR registration

D. Cooperative

Registered with the CDA (Cooperative Development Authority)

E. Foreign corporation doing business in the Philippines

Must obtain an SEC license to do business (and related registrations)

F. Informal business (unregistered)

May be operating without proper registrations (a risk signal)

III. What “properly registered” usually includes (the baseline checklist)

For most businesses, “properly registered” commonly means the business has:

Name / entity registration
- DTI for sole proprietorship business name; or
- SEC for partnership/corporation/OPC; or
- CDA for cooperatives
Local Government Unit (LGU) registrations
- Barangay clearance
- Mayor’s/business permit
- Occupancy / zoning compliance where applicable
BIR registration
- Certificate of Registration (COR)
- Authority to Print (ATP) or approved invoicing system (or e-invoicing compliance as applicable)
- Registered books of accounts (physical or computerized)
- Registered official receipts/invoices and compliance with invoicing rules
Employer registrations (if the business has employees)
- SSS, PhilHealth, Pag-IBIG employer registration and remittances
Regulatory licenses (industry-specific)
- Examples: FDA for food/drugs/cosmetics/medical devices, BSP registration for certain financial activities, DOLE requirements, DENR permits for environmental impact, etc.

When someone claims “registered,” ask: Registered where, and for what?

IV. How to verify registration by business type

A. Verifying a sole proprietorship (DTI + operating registrations)

1) Ask for the DTI Business Name Registration A legitimate sole proprietorship typically can produce:

DTI Certificate of Business Name Registration (often called “BN Certificate”)
Business name, owner name, validity period, and territorial scope (barangay/city/region/national)

What to check

The owner’s name matches the person you’re dealing with (or their authorized representative)
The business name matches exactly (including punctuation and spacing)
The validity period is current
The scope is appropriate (e.g., city-wide vs. national)

2) Confirm they can legally operate in that location Request copies of:

Mayor’s Permit / Business Permit (current year)
Barangay Clearance
For physical stores: proof of occupancy/zoning compliance as applicable

3) Confirm BIR registration Ask for:

BIR Certificate of Registration (Form 2303 / COR)
Sample official receipt/invoice showing:
- Registered business name/trade name (if any)
- TIN
- Registered address
- Registration details required for invoices/receipts

Important practical note: A sole proprietorship’s “business name” is not the same as a corporation’s “company name.” DTI registration does not create a separate legal person; the owner remains personally liable.

B. Verifying a corporation / partnership / OPC (SEC + operating registrations)

1) Ask for SEC documents A properly formed entity should be able to provide:

SEC Certificate of Incorporation (corporations/OPC) or Certificate of Registration (partnership)
Articles of Incorporation/Partnership
By-laws (if applicable)
For OPC: OPC-specific foundational documents (e.g., articles reflecting OPC structure)

What to check

Exact registered corporate name (not just the brand/trade name)
SEC registration number or identifier shown on documents
Incorporators/partners and directors/trustees as applicable
Principal office address
Corporate term and primary purpose

2) Check if the person signing has authority Ask for:

Board Resolution / Secretary’s Certificate authorizing the representative/signatory (for corporations)
Proof of identity of the representative

A common fraud pattern is dealing with someone using a company name but lacking board authority. For contracts, banking, purchases, and credit arrangements, authority is critical.

3) Confirm LGU permits Ask for:

Mayor’s Permit / Business Permit for the current year
Barangay clearance
Proof of branch permits if dealing with a branch location (permits are often location-specific)

4) Confirm BIR registration Ask for:

BIR COR (Form 2303)
Sample invoice/receipt and the business’s registered invoicing method

5) If it has employees Ask (or at least confirm):

Employer registrations with SSS/PhilHealth/Pag-IBIG
Remittance compliance if high-stakes relationship (supplier/contractor)

C. Verifying a cooperative (CDA + operating registrations)

Ask for:

CDA Certificate of Registration
Cooperative’s By-laws
Board resolutions/authority documents for signatories
LGU permits and BIR registration (cooperatives often have tax privileges, but still have registration and compliance requirements)

D. Verifying a foreign corporation “doing business” in the Philippines

Ask for:

SEC License to Do Business (not just a certificate of incorporation abroad)
Proof of local registrations (BIR, LGU permits)
Proof of a local office address and authorized representatives
For cross-border transactions, verify whether they are merely selling from abroad (which can be structured differently) versus “doing business” locally (which generally requires licensing)

V. Where mismatches usually happen (and what they mean)

1) Trade name vs. registered name

Businesses often market under a brand that is different from the registered entity name. That can be legitimate, but the entity must still be identifiable.

What to do: Request the registered legal name and confirm the relationship between the brand and the entity (e.g., “ABC Trading” is a trade name of “XYZ Corporation”).

2) Expired/old permits

LGU permits are typically annual. A business might be real but currently noncompliant.

Risk: Operating without a current permit can expose you to collection issues, enforcement risks, or contract enforceability complications.

3) “DTI-registered” used to imply corporate legitimacy

DTI registration only secures a business name for a sole proprietorship; it is not a corporation.

Risk: You might think you’re contracting with a company when you’re actually contracting with an individual.

4) “SEC-registered” but missing BIR registration

A company can exist legally but still be operating without tax registration and invoicing compliance.

Risk: Receipts/invoices may be invalid; tax deductions/withholding compliance may be affected; enforcement and penalties risk.

5) Wrong address, TIN, or invoice details

A legitimate business’s registrations should align:

Principal office / business address
TIN and registered name format
Permits matching the branch location

Risk: Red flag for identity misrepresentation or a “borrowed” document.

VI. Documents to request (by scenario)

A. Low-stakes purchase (e.g., one-time consumer transaction)

Official receipt/invoice
Business permit displayed on premises (if physical store)
Basic business info (name, address, contact)

B. Supplier onboarding / vendor accreditation

SEC or DTI/CDA certificate
Mayor’s permit & barangay clearance (current)
BIR COR (Form 2303)
Sample invoice/receipt
IDs of owners/officers
Bank account name matching legal entity
For corporations: secretary’s certificate/board resolution for signatory

C. Lending / installment / high-value contract

All of the above plus:

Audited financial statements (if available/required)
Proof of good standing/compliance where applicable
Verification of litigation/insolvency risk as part of due diligence (context-dependent)
Collateral documentation (if any)

VII. Step-by-step verification workflow (practical due diligence)

Step 1: Identify the legal form

Ask: “Is this a sole proprietorship, corporation, partnership, OPC, or cooperative?”

Step 2: Collect core identifiers

Registered name
Trade name/brand (if different)
Registration numbers
TIN
Addresses (principal office and branch)
Names of owners/partners/directors/officers

Step 3: Review registration documents for consistency

Cross-check:

Spelling and formatting of the name
Address alignment across SEC/DTI, BIR, and permits
Authority of signatory

Step 4: Check operating authority for the location

Mayor’s permit and barangay clearance should cover the actual site of operations
For multiple branches, confirm branch permits

Step 5: Verify tax registration and invoicing

COR details align with invoices/receipts
If withholding applies, ensure you’re withholding from the correct entity

Step 6: Confirm employer compliance if relevant

If you are outsourcing labor or contracting services, employer registrations and compliance reduce your risk.

Step 7: Look for red flags

Refusal to provide basic documents
Documents with blurred/partial data, inconsistent formatting, or mismatched addresses
Payments requested to personal accounts when dealing with a supposed corporation
No official invoicing capability for a purportedly established firm

VIII. Common red flags and how to respond

Red flag: They won’t provide SEC/DTI/CDA certificate

Response: Require the documents before payment or contract signing. If they claim confidentiality, offer a controlled review (view-only) but do not proceed without verification.

Red flag: The contract name doesn’t match invoices/permits

Response: Use the registered legal name in the contract and include the brand as a trade name descriptor only.

Red flag: They want payment to a different entity/person

Response: Payment should go to the contracting entity’s account. If there’s a reason (e.g., factoring), require formal documentation and confirm authority.

Red flag: Expired permits / no BIR COR

Response: Treat as a compliance risk; adjust terms (escrow, smaller tranches, COD) or pause until resolved.

IX. Legal and practical effects of dealing with an unregistered business

A. Enforceability of contracts

Contracts are generally enforceable as long as the essential requisites are present, but identifying the correct party is crucial. Misidentification can make collection and enforcement difficult.

B. Personal liability

If you thought you were dealing with a corporation but it’s actually a sole proprietorship, the individual owner may be personally liable—but collecting can still be difficult without accurate identity and address information.

C. Tax and invoicing consequences

If you need valid invoices/receipts for accounting, tax deductions, or withholding compliance, an unregistered or noncompliant supplier can create downstream issues.

D. Regulatory and reputational risk

Partnering with noncompliant entities can lead to operational disruptions and reputational harm, especially in regulated industries or government procurement.

X. Special topics people overlook

1) “Business name” is not the same as a “trademark”

DTI/SEC/CDA registration is about business identity and/or legal existence.
A trademark is about brand protection and is typically handled through IP registration processes. A business can be properly registered yet still infringe someone else’s trademark, or have a trademark without being properly registered to operate.

2) Branches and franchises

A branch often has its own:

LGU permits
BIR branch registration requirements (depending on structure) A franchisee may not be the same entity as the franchisor. Verify the exact entity you’re contracting with.

3) Online sellers and home-based businesses

Even if operating online, if the seller is conducting business regularly, compliance typically still involves business registration, BIR registration, and local permits depending on the business model and locality rules.

4) “In process” registrations

Some businesses operate while still processing registrations. This might be tolerated in practice but is still a risk. If you proceed, use protective terms:

Milestone-based payments
Strong representations and warranties
Right to terminate for noncompliance
Indemnity clauses where appropriate

XI. Suggested contract clauses for verification (high-level)

If you are contracting with a business and want to protect yourself, consider including:

Representation of valid registration (DTI/SEC/CDA, LGU, BIR)
Warranty of authority (signatory has power to bind the entity)
Undertaking to maintain permits during the contract term
Right to audit/inspect compliance documents
Termination for regulatory noncompliance
Indemnity for losses arising from misrepresentation or lack of permits
Correct entity information (registered name, address, TIN, registration number)

(These should be tailored to your transaction and risk profile.)

XII. Quick reference: what to ask for (one-page checklist)

For sole proprietorship

DTI BN Certificate
Mayor’s permit (current year) + barangay clearance
BIR COR (Form 2303)
Sample official receipt/invoice
Valid ID of the owner

For corporation/partnership/OPC

SEC Certificate + Articles (and By-laws if applicable)
Mayor’s permit (current year) + barangay clearance
BIR COR (Form 2303)
Sample official receipt/invoice
Secretary’s certificate/board resolution for signatory + valid ID

For cooperative

CDA Certificate + By-laws
Mayor’s permit + barangay clearance
BIR registration documents as applicable
Board resolution/authority for signatory

For foreign corporation

SEC license to do business
Local permits + BIR registration
Proof of authorized local representative

XIII. Practical takeaways

“Proper registration” is multi-layered: entity/name + local permit + tax registration are the core.
Always verify the legal entity name behind a brand.
For higher stakes, verify signatory authority and require matching payment and invoicing details.
Treat missing or inconsistent documents as a risk, not a minor technicality.
