CAC Name Search Nigeria: How to Check Business Names and Avoid Fraud (2026)

By 9jaDirectory Editorial Team | Published: February 2026

The CAC name search is one of the most used tools on the Corporate Affairs Commission website — and for good reason. Every month, thousands of Nigerians run name searches either to check if their chosen business name is available before registering, or to verify whether a company they are dealing with actually exists. Both are smart moves.

This guide covers both use cases: how to search CAC for a name you want to register, and how to use the same search to verify any existing Nigerian business before you sign a contract, pay a deposit, or commit your money.

Two Reasons to Run a CAC Name Search

Before going further, it helps to understand the two distinct reasons people use the CAC name search tool:

Use Case	Who Does This	What They Are Looking For
Name availability check	Entrepreneurs about to register a business	Is this name already taken? Can I use it?
Business verification	Buyers, investors, job seekers, contract signers	Is this company real and legally registered?

The tool is the same — the CAC public search portal — but your goal determines what you do with the results. Let us walk through both scenarios.

Use Case 1: Checking Name Availability Before Registration

The CAC will not register a business name that is identical or confusingly similar to an existing registration. Before you invest time preparing documents or paying fees, run a name search first. It takes two minutes and costs nothing.

How to Check if a Business Name Is Available

1. Visit search.cac.gov.ng or go directly to pre.cac.gov.ng and use the name availability checker in the registration flow.
2. Type your desired business name exactly as you plan to register it.
3. Review all results that appear. Look for any name that is identical or very similar to yours.
4. If no close match appears, your name is likely available — but not guaranteed until you reserve it.
5. Prepare a second alternative name in case your first choice fails at the reservation stage.

Pro tip: Even if a name does not appear in the public search, it could still be reserved by another applicant in the CAC system. Always have a backup name ready. Struck-off names can be re-registered, but the process takes additional steps.

What Makes a Name Acceptable to the CAC?

Not all names pass CAC approval. Understanding the rules saves you from wasted name reservation fees. The CAC will reject or query a name that:

• Is identical or deceptively similar to a registered business or company name
• Contains restricted words without approval — including "Federal," "National," "Government," "State," "Municipal," "Chartered," "Bank," "Insurance," or "Trust"
• Is offensive, vulgar, or contrary to public policy
• Implies a connection with the Nigerian government or royalty without evidence
• Contains foreign words without an English translation or explanation
• Is so generic it could apply to any type of business (though this is applied inconsistently)

Good names are specific, distinctive, and describe what the business does without triggering the restricted words list. "Alara Engineering Services Limited" is far more likely to pass than "Nigerian Engineering Trust."

Use Case 2: Verifying an Existing Business

If someone presents you with a business certificate, invoice, or contract, the CAC name search is your fastest verification tool. Here is a methodical approach:

Step-by-Step: Verifying a Business Before You Pay

1. Get the full registered name: ask for the company's exact registered name and RC number — not just their trading name or brand name.
2. Search by name first: go to search.cac.gov.ng and enter the name. Confirm a match exists.
3. Cross-check the RC number: if the name matches, then search by the RC number they provided. The result should show the same entity name.
4. Check the status: confirm the status reads "Active." If it shows "Struck Off" or any other status, investigate further before proceeding.
5. Note the registration date: a company claiming years of experience but registered recently is worth questioning.
6. Compare the registered address: see if the address on CAC matches what they have told you or shown on their materials.

Common CAC Name Search Mistakes to Avoid

Searching an abbreviation instead of the full name

Many companies are registered under a full formal name but trade under an abbreviated or shortened name. If you search "ABC Consult" but they are registered as "ABC Consulting Services Limited," you will not find a match. Always request and search the complete registered name.

Assuming no result means no registration

CAC's search engine is not perfect. A result may fail to appear due to a spelling variation in the database or a system delay after recent processing. If the search returns nothing but the company insists they are registered, ask them to produce the physical certificate with the RC number and search by that number instead.

Not checking entity type

A search may return a result but it could be an Incorporated Trustee (IT) — a church or NGO — rather than the limited liability company the vendor claims to be. Check the entity type field carefully. An NGO operating as a for-profit contractor should raise questions.

Stopping at the name search alone

For any high-value transaction, name search is a starting point, not a finish line. Combine it with a request for the actual CAC certificate, check if annual returns have been filed, and for very large sums, obtain a certified true copy of the company's filing from CAC directly.

What to Do After a Successful Name Search

If you are registering a new business and your name is available, the next step is formal name reservation through the CAC pre-incorporation portal at pre.cac.gov.ng. Name reservation locks your chosen name for 60 days while you complete the registration forms.

Once registered, your next move is visibility. A registered business with no online presence is invisible to the customers searching for what you offer.

Frequently Asked Questions

Is the CAC name search free?

Yes. Searching for a name on the CAC public portal at search.cac.gov.ng is completely free. You only pay when you move to the formal name reservation step inside the CAC pre-incorporation portal, which requires a government fee.

Can two businesses have the same name in Nigeria?

No. The CAC will not register a business name that is identical or confusingly similar to an existing registration. However, similar-sounding names can sometimes slip through. This is why verifying the exact RC number of a business — not just the name — is important before a major transaction.

What happens if I reserve a name and do not complete registration?

CAC name reservation is valid for 60 days. If you do not complete your registration within that period, the reservation expires and the name becomes available for others to register. You can re-reserve the name but you will need to pay the reservation fee again.

Can I search for CAC-registered NGOs and churches?

Yes. The CAC public search covers all entity types including Incorporated Trustees — the category under which NGOs, churches, mosques, associations, and foundations are registered. Their registration numbers are prefixed with "IT" rather than "RC." Search by the organisation name the same way you would for any other business.
