I. Introduction

In the Philippines, the Securities and Exchange Commission (SEC) is the primary government agency tasked with registering and regulating corporations, partnerships, and certain other juridical entities. For many business dealings—supplier onboarding, investments, acquisitions, employment, franchising, lending, real estate purchases, and everyday contracting—one of the most practical starting points for due diligence is the company’s SEC registration number.

This article explains, in Philippine legal context, what an SEC registration number is, what it can and cannot prove, how it fits into corporate identity and authority, and how it should be used—together with other documents and checks—to evaluate whether a “company” is legitimate, duly existing, and authorized to act.

II. What the SEC Registration Number Is

A. Concept and Function

An SEC registration number is a unique identifier assigned by the SEC to an entity upon registration (or, for older entities, upon recording/recognition under prior systems). It functions as a reference number for SEC records relating to:

the entity’s formation documents (e.g., Articles of Incorporation/Partnership);
subsequent filings and reports (e.g., General Information Sheet or “GIS”);
amendments (e.g., change of corporate name, increase of capital, change in principal office);
compliance status (e.g., delinquent, suspended, revoked, dissolved).

In practice, the SEC registration number is one of the most common data points used to locate the entity’s official filings and to match a company’s claimed identity against public and official records.

B. What Entities Have SEC Registration Numbers

Typically, an SEC registration number is associated with entities that register with the SEC, including:

Stock and non-stock corporations
Partnerships (including professional partnerships, general partnerships, limited partnerships)
Foreign corporations licensed to do business in the Philippines (e.g., branch, representative office)
Other entities required by law or regulation to register with the SEC

Important distinction: Sole proprietorships are generally registered with the Department of Trade and Industry (DTI) rather than the SEC. If a person claims a “company” is SEC-registered but is actually a sole proprietorship, the SEC number should not exist; the relevant registry would be DTI.

III. Why the SEC Registration Number Matters in “Legitimacy” Checks

“Legitimacy” in business use often means one or more of the following:

Legal existence (the entity exists as a juridical person recognized by law)
Authority to operate (it is registered/licensed and not prohibited from doing business)
Authority of the signatory (the person signing can bind the entity)
Authenticity of identity (the entity is not falsely claiming another’s name)
Compliance standing (not delinquent/suspended/revoked)
Regulatory fitness (proper registrations with other agencies and local government)

An SEC registration number is most directly relevant to items (1), (4), and partially (2) and (5). It does not, by itself, fully resolve (3) or (6).

IV. The Legal Backbone: Corporate Existence and SEC Registration

A. Juridical Personality and Registration

Under Philippine corporate principles, a corporation becomes a juridical person upon compliance with legal requirements and SEC registration. Once formed, it can own property, sue and be sued, enter contracts, and undertake activities allowed by its purpose and the law.

B. Primary Evidence of Existence: SEC-Certified Records

In disputes, the strongest evidence of corporate existence and corporate acts often comes from SEC-certified copies of formation documents and relevant filings. While an SEC registration number helps locate records, the official documents themselves (and their SEC certification, when needed) carry evidentiary weight.

V. What the SEC Registration Number Can Prove—and What It Cannot

A. What It Can Reasonably Indicate (When Matched to Records)

If the SEC registration number matches SEC records showing an active, existing entity, it can indicate:

the entity has been registered with the SEC;
the corporate/partnership name tied to the number is real (as recorded);
the date of registration and corporate details exist in the SEC’s registry;
filings associated with that number can be traced and reviewed.

B. What It Cannot Prove by Itself

An SEC registration number alone does not automatically prove:

Current good standing A company can have a valid registration number yet be delinquent, suspended, revoked, dissolved, or have lapsed authority to operate (e.g., for failure to submit reports).
Authority to transact a specific deal Even an active corporation may lack authority for a specific transaction if it’s outside its purposes or requires approvals.
Authority of the person you are dealing with Corporate acts require proper authorization. You must verify the signatory’s authority (board resolution, secretary’s certificate, special power, etc.).
Absence of fraud or impersonation Scammers may use a real SEC number belonging to a different entity or present altered documents.
Registration with other agencies Tax registration (BIR), business permits (LGU), and sectoral licenses (e.g., BSP, Insurance Commission, DOE, LTFRB, HLURB/DHSUD-related, etc.) are separate matters.

VI. Practical Due Diligence Using the SEC Registration Number

The SEC number is a “key” to a file. The core task is matching and cross-checking.

Step 1: Match the Claimed Identity Against SEC Core Data

Ask for (or obtain) the following and ensure they match each other consistently:

Exact corporate/partnership name (including “Inc.”, “Corp.”, “Foundation”, “Co.” where applicable)
SEC registration number
Principal office address
Date of registration/incorporation
Type of entity (stock/non-stock; domestic/foreign; partnership)

Red flags: slight name variations, missing suffixes, different addresses, inconsistent dates, or “brand names” being presented as if they are the legal entity name.

Step 2: Review the Formation Document(s)

Depending on the entity:

Corporation: Articles of Incorporation and, if relevant, By-Laws
Partnership: Articles of Partnership and amendments

Key items to read:

Corporate purpose(s): Are they allowed to do what they claim?
Capital structure (for stock corporations): authorized capital, subscribed/paid-up
Incorporators/partners and initial directors/trustees
Term of existence (where applicable under current law and amendments)
Principal office location

Step 3: Review the Latest General Information Sheet (GIS) or Equivalent Disclosures

The GIS is commonly used to validate:

current directors/trustees/officers
principal office address updates
stockholders/members information (depending on required disclosures)
corporate secretary and treasurer
ownership and control indicators (as disclosed)

Red flags: outdated GIS, major changes not reflected, inability to provide a current filing, inconsistencies with what the counterparty claims.

Step 4: Check Corporate Status and Compliance

Businesses sometimes exist on paper but are not compliant. Look for indicators of:

delinquency for non-filing
suspension/revocation of registration
dissolution (voluntary or involuntary)
amendments that changed the name (a “new” name may still be under an older number)

Step 5: Verify Authority to Sign and Bind the Entity

For any transaction of legal consequence (supply contracts, services agreements, loans, leases, purchases, investments), require appropriate authorizations, typically:

Board Resolution (for corporations) authorizing the transaction and naming the authorized signatory; and/or
Secretary’s Certificate attesting to the resolution; and/or
Special Power of Attorney (if an agent signs); and/or
For partnerships, proof that the partner signing has authority under the partnership agreement or by consent.

Best practice: Verify the corporate secretary’s identity and confirm the authority is still valid and not revoked.

Step 6: Confirm the Entity’s Operational Footprint Outside the SEC

For broader legitimacy:

BIR Certificate of Registration (COR) and invoices/receipts compliance
Mayor’s/Business Permit from the LGU where it operates
DTI registration (if a sole proprietorship is involved) or for trade names
PhilGEPS registration (if dealing with government procurement; not mandatory in private transactions but informative)
Relevant sectoral licenses (e.g., lending/financing companies, insurance, brokerage, energy, transportation, real estate development, manpower agencies, etc.)

The SEC registration number is one piece; most “operating legitimacy” is confirmed by BIR/LGU/sector regulators.

VII. Frequent Scenarios and How the SEC Number Helps

A. Supplier/Contractor Onboarding

Use the SEC number to match the legal entity, then demand proof of signatory authority.
Confirm the entity isn’t merely a “trade name” with no juridical person behind it.

B. Investment Offers and Fundraising

Confirm the issuer exists and is the entity offering securities/investment.
Remember: SEC registration of the entity is not the same as SEC compliance for offering “securities” to the public. Additional rules may apply depending on the instrument and the manner of offering.

C. Real Estate Purchases or Leasing with a Corporate Seller/Lessor

Ensure the entity exists and the signatory is authorized.
Cross-check property title ownership against the corporation name exactly (including suffix).

D. Employment and Labor Contracting

Ensure the employer entity is the one registered and the one paying salaries and withholding taxes.
For manpower/agency arrangements, check for industry-specific compliance beyond SEC.

E. Foreign Corporations

Confirm whether the foreign corporation is merely registered in its home jurisdiction or is properly licensed/registered to do business in the Philippines (branch/representative office, etc.).
Contract enforceability and capacity can be affected if required licensing is absent for “doing business” locally.

VIII. Common Red Flags in SEC-Number-Based “Legitimacy” Checks

SEC number does not match the entity name presented to you.
The counterparty uses a brand/trade name but cannot show the underlying registered entity and the relationship (e.g., a corporation owning the brand).
Pressure tactics: “Sign now,” “confidential—no documents,” “we’ll send later.”
Provided documents look like screenshots with inconsistent formatting or contain mismatched dates, names, or addresses.
The signatory claims to be an officer but is not listed in the latest GIS and cannot produce a board authorization.
The company claims to be a corporation but only has DTI paperwork (suggesting sole proprietorship).
The entity appears registered but has no operational registrations (no BIR/LGU) for a business that would ordinarily need them.

IX. Legal Consequences of Getting It Wrong

A. Contracts With a Non-Existent or Unauthorized Entity

If the “company” does not exist, the agreement may not bind any juridical entity; you may end up chasing individuals or fraudsters.
If the entity exists but the signatory lacks authority, the contract may be voidable or unenforceable against the corporation unless later ratified.

B. Corporate Veil and Personal Liability Considerations

While corporations generally protect shareholders from personal liability, Philippine law recognizes situations where individuals can be personally liable (e.g., fraud, bad faith, certain statutory obligations). From a practical standpoint, verifying the real registered entity and the authorized signatory helps prevent situations where you must later argue exceptions.

C. Regulatory and Compliance Exposure

If you deal with an entity misrepresenting licensing status, you may expose your business to compliance issues, reputational risk, and operational disruptions (e.g., invalid permits, tax issues, sectoral enforcement actions).

X. Best Practice Checklist for Private Transactions

When relying on an SEC registration number, the most defensible process is a “match, verify, authorize” routine:

Match identity
- SEC number + exact registered name + address + entity type
Verify existence and filings
- Formation documents (and amendments)
- Latest GIS and relevant updates
Verify authority
- Board resolution/secretary’s certificate naming the signatory
- Government ID of signatory; specimen signature if needed
Verify operational compliance
- BIR COR
- LGU business permit
- Sectoral licenses (if applicable)
Document your due diligence
- Keep copies, screenshots, and correspondence
- Record date/time and source of documents
- For higher stakes, obtain certified true copies where appropriate

XI. Notes on Evidence and Documentation

For significant transactions, it is prudent to obtain documents in a form that can be relied upon in court or in administrative proceedings. In many cases, that means:

keeping complete, legible copies;
ensuring consistency across all documents;
requiring certifications where appropriate; and
documenting how you received and verified documents.

If there is any dispute about corporate identity, corporate status, or authority, SEC-certified documents and formally executed corporate certificates become especially important.

XII. Conclusion

An SEC registration number is a powerful anchor for corporate due diligence in the Philippines because it ties a counterparty’s claims to a traceable set of official filings. But it is not a “magic stamp” of legitimacy. The correct legal approach is to use the SEC number to retrieve and match corporate records, confirm the entity’s standing, and—most critically—confirm the authority of the person acting for the entity. For real-world protection, combine SEC-number verification with BIR, LGU, and sectoral checks, and retain documentation proportionate to the risk and value of the transaction.
