How to Verify a Nigerian Company: CAC, TIN, Address and Red Flags

Before paying a supplier, hiring a contractor, signing a partnership, renting property, choosing a logistics provider or onboarding a vendor, you should know how to verify a Nigerian company.

A business can have a nice logo, active social media page and convincing sales message, but that is not enough. Verification means comparing official records with the real-world details the business gives you: name, registration number, address, phone number, website, invoice, bank account and service claims.

This guide explains how to use CAC public search, RC or BN numbers, TIN verification, sector checks, online profiles and red-flag checks before you pay or sign anything important.

What does it mean to verify a Nigerian company?

Verifying a company means checking whether the business identity is consistent and credible across multiple sources.

For serious transactions, do not rely on one screenshot or one search result. Check the CAC record, tax identity where needed, address, website, phone number, email address, invoice, contract details, online business profile and any regulator that applies to the industry.

The goal is not to prove that every registered business is safe. Registration is only one signal. The goal is to reduce avoidable risk before you send money, share sensitive documents or sign a contract.

Step 1: Ask for the correct business name

Start with the exact registered name, not only the brand name.

Many Nigerian businesses trade with a shorter public name but register a longer legal name with CAC. For example, a brand may use a short trading name on Instagram, while the CAC record contains a full company name ending with Limited.

Ask for:

• Registered business name or company name
• RC number, BN number or IT number where available
• Business address
• Official website or verified profile link
• Invoice or proposal carrying the same business details

Step 2: Search CAC public records

CAC public search allows users to search existing companies and business entities. The public search page includes options such as all records, RC number, AV code and approved name.

Use CAC public search to compare the business name and registration details you were given. If you have the RC or BN number, search with that number. If you only have the name, search by approved name or all records and compare carefully.

When checking CAC records, look for:

• Registered name
• Registration number
• Entity type
• Status where available
• Whether the result matches the business you are dealing with

If the registration number leads to a different name, pause. If the business refuses to provide a registration name for a serious transaction, ask more questions.

Step 3: Understand RC, BN and IT numbers

A limited company usually has an RC number. A registered business name usually has a BN number. An incorporated trustee usually has an IT number.

People sometimes call all of these a company code, but they are not always the same. If you need a deeper explanation, read our guide to company code in Nigeria, RC number and BN number.

The number should match the entity type. A sole proprietor with a registered business name may give a BN number, not an RC number. An NGO may give an IT number.

Step 4: Verify TIN when tax identity matters

For vendor onboarding, corporate procurement, tax invoices, bank forms and government processes, CAC registration may not be enough. You may also need to verify tax identity.

The Nigeria Revenue Service TIN verification system allows search using TIN, RC/BN or phone number. Use it when you need to confirm tax identity or compare tax registration details with CAC details.

If the tax record, registered name and invoice details do not align, ask for clarification before proceeding.

Step 5: Compare address, website and contact details

Official registration is useful, but practical verification also depends on contact details.

Check whether the business address, phone number, email address and website appear consistently across:

• CAC or registration documents
• Company website
• Invoices and contracts
• Business directory profiles
• Google Business Profile or map listings
• Social media profiles

A mismatch is not always fraud. Businesses move offices, rebrand or change phone numbers. But unexplained mismatches should slow you down.

Step 6: Check sector licences and regulators

CAC registration does not prove that a company is licensed to operate in every sector.

Some industries need additional approvals, licences or professional membership. Examples can include banking, insurance, healthcare, schools, legal services, real estate, travel, oil and gas, construction, security, food, pharmaceuticals and designated non-financial businesses.

If a company claims to offer a regulated service, check the relevant regulator or professional body before paying.

Step 7: Review online business profiles

A directory profile does not replace official verification, but it helps you compare public details.

On MyNigeriaBusiness.NG, a useful profile should help users review business name, category, location, phone number, website, services and profile information. You can start from the Nigeria business directory or browse businesses by category and location.

If you own a legitimate business, a complete public profile helps customers verify your identity and understand what you do.

Step 8: Ask for proper invoice and contract details

For serious transactions, ask for an invoice, contract or purchase order that carries the same identity details you verified.

Check:

• Business name
• Registration number where included
• Address
• Email and phone number
• Bank account name
• Service description
• Payment terms
• Refund or dispute terms where relevant

If the bank account name is unrelated to the business name, ask for a clear explanation and supporting documentation.

Red flags when verifying a Nigerian company

• The business name does not match the CAC result.
• The RC or BN number belongs to another entity.
• The business refuses to provide registration details for a serious transaction.
• The address cannot be confirmed.

• The company claims to be licensed in a regulated sector but cannot show evidence.
• You are pressured to pay before seeing an invoice or contract.
• The business only communicates through temporary or anonymous channels.
• Online reviews or complaints reveal repeated unresolved issues.
