A queried business name application is rarely personal. It is almost always one of a few recurring problems.
A name too close to one already registered
CAC will not register a business name that is identical, or close enough to be confused, to one already on the register. This is a common reason for a query.
A small spelling change, a different word order, or dropping a common word often still counts as too similar. Search the public register yourself before you apply. The check costs nothing, and a query afterwards wastes your reservation fee.
A restricted word used without the extra fee
Some words need extra approval, at a higher fee than the standard one. Check CAC's published list of restricted words if your proposed name might be affected.
Reserving one of these costs ₦5,000, not the standard ₦1,000. See CAC company name reservation: fee and validity for how that gap works. Applying at the lower fee, or without the right supporting approval, is a common cause of a query, and sorting it out still eats into your up to 60 days reservation window.
Proprietor details that do not match an ID
CAC checks the proprietor's name, address and other details against the identification submitted. A spelling difference between the form and the ID is enough to trigger a query.
Copy the name exactly as it appears on the identification document, not as it is usually written or spoken. A middle name left out on one document but not the other causes the same problem, and so does a title added on one form but missing from the ID.
An address CAC cannot verify
An incomplete street name, a missing local government area, or an address that does not match the supporting document can also hold up an application.
Write the address the way it appears on a utility bill or tenancy agreement, rather than a shortened version you use casually. A landmark description on its own, without a street name or number, rarely satisfies this check.
What to do once a query is raised
Read the reason CAC gives before you do anything else. It usually points to one of the problems above, not something new.
If it is a name clash, change the wording enough to stand apart, not just one letter. If it is a restricted word, decide whether the business genuinely needs it. If it is a details mismatch, correct the spelling and resubmit.
Have a backup name ready before you apply the first time, so a query does not cost you a second full wait from scratch. Our how to register a business name at CAC guide covers the full process from a clean start. Browse the CAC registration hub for more on avoiding a rejected application.
