What "available" really means for a business name
A business name can be free in one sense and taken in another. There are four separate checks, and they are run by different organisations:
- Domain. Controlled by registries such as Verisign (.com). This page checks it live.
- Trademark. Rights come from use and registration with a trademark office, and they apply per class of goods and services. Two companies can share a name in unrelated classes (Delta Air Lines and Delta faucets).
- Company register. Your state (US) or Companies House (UK) will refuse a name that is too similar to one already filed, but registering does not grant trademark rights.
- Social handles. First come, first served on each platform. Worth grabbing the same day you register the domain.
Trademark conflicts are the expensive ones. If the name will carry real investment, have a trademark attorney run a clearance search before you print anything.
Frequently asked questions
How do I check if a business name is taken?
Check four places: domain availability (this tool does it live), your trademark office (USPTO in the US, UKIPO in the UK, EUIPO in the EU), your state or national company register, and the social platforms you will use. The checker gives you one-tap links to each.
Is a business name taken if the .com is registered?
Not necessarily. A registered domain only means someone owns that address. The name may still be free to use as a business name, but you would need a different domain and should check trademarks carefully.
What does the name score measure?
It is a quick heuristic for how easy the name is to say, spell and remember: length, consonant clusters, vowel balance and spellings that fail the radio test (ph, gh, silent letters). It says nothing about legal availability.
Does registering an LLC protect my business name?
Only within that state's entity register. It does not give trademark rights, and someone with an earlier trademark could still stop you using the name. A federal trademark gives nationwide protection in the US.
What does the AI review do?
On request, a language model gives a short verdict on the name's meaning, sound, spelling and distinctiveness, and suggests two alternatives. It never claims a name is legally available.
