Is my business name taken? Check by state (all 50 states and DC)
By Keencrest · 2026-11-01
A business name has to clear four separate registers, and no single search covers them: the state's entity register, the county or city for assumed names, the federal trademark database, and the domain system. Pick your state for the official search link and the notes on what it misses.

Link checks
We loaded each state's search address on 2026-11-01. 30 reached a page; 21 refused or did not answer a plain request (mostly HTTP 403 from the state's web firewall), and those are marked "link not verified" on their pages. We did not work around the blocks.
The federal layer
Trademarks are registered nationally, not by state: USPTO trademark search.
Outside the US
UK, Australia, Ireland, New Zealand and every Canadian province: business name check outside the US.
The domain layer
Check a list of names against many extensions at once with the Bulk Domain Availability Checker, $0.001 per domain answered.
Try it: Bulk Domain Availability Checker on Apify. $0.001 per domain answered, unknown rows free. The Apify free plan includes monthly credit, so a test run costs nothing out of pocket.
