Wisconsin Name Search FAQ

Is this the same data as the Wisconsin DFI website?

Yes. Every search queries the Wisconsin Department of Financial Institutions corporate records database live, using DFI's own name-availability matching — the same check the state runs. Results are briefly cached for speed, and every search links back to the identical query on DFI's site so you can verify for yourself.

If my name shows as available, is it reserved for me?

No. Availability can change at any moment until a filing lands, and only DFI makes the final determination — your name must be distinguishable from existing records (Wis. Stat. §§ 180.0401, 181.0401, 183.0112). The fastest way to secure a name is to file your LLC. Wisconsin also offers a 120-day name reservation through DFI if you're not ready to form yet.

Does an available business name mean I can trademark it?

Not necessarily — state entity registration and federal trademark rights are separate systems. A name can be free in Wisconsin's registry and still step on someone's trademark. If the brand matters to you, pair your formation with a USPTO trademark search & registration.
