If you have ever filled in a form for a bank, a government portal, or a corporate client and been asked for your "company code," you may have wondered exactly what that means. In Nigeria, the term covers several different identifiers — and using the wrong one can cause delays, rejected applications, or failed verifications.
This guide explains every Nigerian company code in plain English: what each one means, where it comes from, how to find yours, and how to verify any other company's code using the CAC public search tool.
What Is a Company Code in Nigeria?
In everyday Nigerian business usage, "company code" most often refers to the RC number — the unique Registration Certificate number assigned by the Corporate Affairs Commission (CAC) when a business is registered. However, the full picture is slightly more complex. There are several official codes a Nigerian business may carry, depending on its structure.
| Code Type | Prefix | Issued By | Who Uses It |
|---|---|---|---|
| RC Number (Company) | RC | CAC | Private Ltd, PLC, LLP companies |
| BN Number (Business Name) | BN | CAC | Sole proprietors and partnerships |
| IT Number (Incorporated Trustees) | IT | CAC | NGOs, churches, associations |
| TIN (Tax ID Number) | None (numeric) | FIRS / Joint Tax Board | All registered businesses for tax filing |
| SCUML Code | Varies | SCUML (via NFIU) | Businesses in regulated sectors (legal, accounting, real estate) |
When a bank, government portal, or corporate client asks for your "company code," they almost always mean your RC number (for limited companies) or BN number (for sole proprietors). These two are the most commonly requested.
RC Number: The Primary Company Code in Nigeria
The RC number is your company's unique fingerprint in Nigeria's official business register. It never changes, never expires, and is tied to your specific registration — not to the directors, shareholders, or any individual. Even if ownership changes completely, the RC number remains the same.
What Your RC Number Looks Like
An RC number for a limited company typically looks like: RC 1234567 — the letters "RC" followed by a 6 or 7-digit number. Older registrations may have shorter numbers. Business names (sole proprietorships) registered with CAC carry a BN prefix: BN 123456.
Where to Find Your RC Number
- Certificate of Incorporation — it appears prominently on the certificate issued by CAC after successful registration
- CAC status report — downloadable from your account on post.cac.gov.ng
- Company letterhead and invoices — reputable Nigerian companies print their RC number on all official documents
- Corporate bank account documents — banks require and record the RC number when opening business accounts
- CAC public search — if you know your registered name, search at search.cac.gov.ng to retrieve the RC number
How to Verify a Company Code (RC Number) on CAC
If you have been given a company code by a vendor, contractor, or business partner, verifying it takes under five minutes. Here is the process:
- Go to search.cac.gov.ng.
- Switch to the "Search by RC Number" tab or option.
- Enter the full RC number including the prefix (RC, BN, or IT).
- Click Search.
- Confirm the registered name matches the business you are dealing with.
- Check that the status reads Active.
- Note the entity type and registration date for further context.
Watch out: A company code that returns no results on the CAC portal is a major red flag. Either the number is fake, the business is not registered, or a typo was made. Always ask for the physical certificate and verify the number printed on it matches what they provided verbally.
Company Code Lists: What They Are and When They Matter
Some industries and government databases maintain "company code lists" — internal reference numbers that identify businesses within a specific system. For example:
- Central Bank of Nigeria (CBN): assigns bank codes (3-digit codes) that identify each licensed bank in Nigeria
- FIRS: uses TIN numbers to track tax filings across all registered entities
- PENCOM: assigns Pension Fund Administrator (PFA) codes to licensed pension managers
- SEC Nigeria: assigns registration codes to capital market operators
- NCC: assigns carrier codes to licensed telecom operators
If a form asks for a "company code" in one of these regulated sectors, it may be asking for the sector-specific code rather than your CAC RC number. Read the context carefully or contact the relevant agency to confirm which identifier they need.
Make Your Company Code Visible to Customers
One practical reason to understand your company code is trust-building. Customers and corporate clients increasingly ask to see a company's RC number before transacting. Displaying your RC number on your website, invoices, and business directory listing signals transparency and professionalism.

Frequently Asked Questions
What is an RC number in Nigeria?
An RC number (Registration Certificate number) is the unique identifier assigned by the Corporate Affairs Commission (CAC) to every registered Nigerian company. It appears on the Certificate of Incorporation and never changes, even if the company changes directors, shareholders, or address. It is the primary "company code" used by banks, government portals, and corporate clients to verify a business.
Is the RC number the same as the TIN?
No. The RC number is issued by the CAC and identifies a company in the business register. The TIN (Tax Identification Number) is issued by the Federal Inland Revenue Service (FIRS) and identifies a business for tax purposes. Both are required for operating a legitimate Nigerian business, but they come from different government agencies and serve different purposes.
What does a company code starting with "BN" mean?
A BN prefix indicates a Business Name registration — a sole proprietorship or partnership registered under a business name. This is different from an RC (limited company) registration. Business Name owners are personally liable for all business debts, unlike directors of a limited company who have limited liability protection.
Can I find a company's RC number if I only have their name?
Yes. Go to search.cac.gov.ng, search by the company name, and the RC number will appear in the search results alongside the registration status and entity type.
