Ready to file? We link you straight to where LLCs and trademarks get filed.
BizNameChecker is a checking tool. Filing happens with the state or the USPTO.
How to clear a business name
Four checks stand between a name idea and a name you can actually use. Here is the order that saves you money.
Your state will reject a filing that conflicts with an existing registration, and the filing fee does not come back. Check the state registry first, in every state you might form in.
DC and Alaska are covered too. They are not shown on this map.
Frequently asked questions
How do I check if a business name is taken?
Type the name once. We check state business registrations, domain extensions, federal trademark records, and social handles in one search.
Is it really free?
Yes. No account, no card, no sign-up. We may earn a referral commission if you form your business through a partner link, which is how the tool stays free.
Which states are instant?
Ten states answer directly from our own corpus of official registrations: New York, Florida, Texas, Pennsylvania, Colorado, Oregon, Connecticut, Iowa, Washington DC, and Alaska. Every other state can be checked live on demand.
What does a trademark match mean?
It means a federal mark with a similar name exists in the USPTO register. It is not a legal opinion and not a clearance. For anything you plan to rely on, talk to a trademark attorney.
Do you register domains?
No. We check availability and link you out to register wherever you prefer. We are not a registrar and we never mark up or sell domains.
How do the social handle checks work?
Platforms with a reliable way to check get a direct answer. Platforms without one get an honest manual-check link instead of a made-up verdict.
How does BizNameChecker make money?
Referral commissions when you choose to use a partner link after seeing your results. We show no ads and sell no personal data.
Do I need an account?
No. There are no accounts. Search as much as you need within the daily limits.
Can I check names from AI tools like Claude?
That is in the works. An MCP integration is coming so you can run name checks from AI assistants.
