How to check if a business name is taken
I'll be Frank
A name can be free in your state and still belong to someone else. Check the .com, your state's business records and the federal trademark database before you order the mugs. It takes about fifteen minutes.
Where a name can be taken
There isn't one master list. A name can be claimed in four different places, and each one covers something different:
| Where | What it covers | Where you check |
|---|---|---|
| Domain | Your web address | SideFrog, or any registrar's search |
| State business records | LLCs and corporations registered in one state | Your Secretary of State's business search |
| DBA (“doing business as”) | A trade name, filed with your state, county or city | Depends on the state; the business search page usually says |
| Federal trademark | A name for a kind of goods or services, nationwide | The USPTO's trademark search |
Fifteen minutes. Shorter than the meeting about the meeting.
Check it in this order
- The domain. It's the fastest no. Type the name into SideFrog with your idea and it checks the .com live.
- Your state's business search. Search “[your state] secretary of state business search.” Look for exact matches and names that differ only by a word like “Co.” or “LLC.”
- DBA records. Some states keep these with the state, others with the county or city. Your state's business search page usually says where.
- The federal trademark search. Search the USPTO's trademark database for your name and close spellings. Pay attention to names used for the same kind of business as yours.
The one to take seriously
A similar name in the same line of business is the kind of “taken” that can cost you later. “Shellbite” for turtle food and “Shellbite” for a seafood restaurant are a different situation from two turtle food companies with the same name. If you find something close in your field, that's a question for a trademark attorney, not SideFrog.
What “available” means at each step
When your state says a name is available, it means no other company registered in that state has that exact name. It doesn't give you rights anywhere else, and it doesn't clear a trademark. An open .com only means nobody owns that address today.
If it's taken
Small changes often fix a domain problem: a second word, a different ending, dropping “the.” They don't fix a trademark conflict in your line of business. If you're stuck, run the idea through SideFrog again; every answer comes with names whose .com is open right now.

Questions people ask
Does registering with my state protect the name everywhere?
No. A state registration covers that state's business records. Nationwide protection for a brand name comes from a federal trademark, which is a separate process.
What if the name is close but not the same?
Close names matter most when the businesses are similar. If you find a near match in your line of work, a trademark attorney can tell you whether it's a problem.
Can two businesses have the same DBA?
Often, yes. Several businesses in one state can use the same trade name, which is why a DBA alone doesn't protect a name.
