Name looks good? Register it with FastCAC in 24 hours. Blocked? Try one of CAC's suggestions.
Why check before you register
CAC rejects names that are taken, too similar to one that is, or break its rules. A quick check shows you:
- Whether the name is taken, or too close to one that is
- Whether it uses a word CAC restricts, like Bank, Federal or Group
- Names CAC suggests instead when yours won't pass
Questions you may have.
Is this the same as CAC public search?
Not exactly. CAC public search finds businesses that are already registered: use our free CAC public search tool for that. This checker asks CAC's name-compliance engine whether it would accept a new name, which a public search can't tell you.
Can I find a company's RC number by its name?
Yes, with our free CAC public search: type the business or company name and each result shows its RC number (BN number for a business name). This page checks new names instead.
Is this CAC name checker really free?
Yes. Checking names costs nothing and needs no account. If you check a lot of names in a few minutes we may ask you to wait briefly, so CAC's service stays fast for everyone.
Where does this data come from?
The availability check uses CAC's own name-compliance engine, the same one behind CAC's bulk-registration portal. It checks the name against the register (taken or too-similar names) and against CAC's naming rules (restricted words, missing endings like "Ventures"). The business lookup searches CAC's public registry.
Why do you ask what my business does?
CAC checks the name together with your line of business. Some names need a matching activity, and some activities need a professional certificate, so the same name can pass for one business and fail for another.
If the checker says a name looks good, is it guaranteed?
It's CAC's own check, so it's the best signal you can get before applying, but CAC confirms the name when it reviews your application. If CAC's service is busy we tell you so and ask you to try again. We never guess.
Can I check company names, business names, and NGOs?
Yes for business names (sole proprietorships and partnerships) and companies: pick "Company (Ltd)" and end the name in Limited, Ltd or PLC. Limited Partnership (LP), LLP and Incorporated Trustee (NGO) names can't be checked for availability here yet. To see what's already registered under those, use our CAC public search and pick the category.
Can I get the Tax ID (TIN) for a result?
Yes, with our free CAC public search: find the business, select it and click "Get Tax ID (TIN)", where available.
Can I get help on WhatsApp?
Yes. After a check, tap "Continue on WhatsApp". It opens WhatsApp with a message to FastCAC ready to send. Send it and we reply there with your result and help registering. Nothing is shared unless you send the message.
I found a name that's available — what next?
You can register it with FastCAC in as little as 24 hours, one flat fee, complete with your official CAC certificate. Still deciding? Our free business name generator suggests ideas you can check here.
