How do I check if a business name is available?

Check four things: a matching domain, your state's business registry, the federal trademark database (USPTO), and the social media handles you want. If all four are clear, the name is safe to use.

Is checking the domain enough?

No. An available domain is a great first signal, but you should also confirm the name is not already trademarked or registered as a business in your state — otherwise you could face legal issues later.

How can I find an available business name fast?

Use Nametastic's generator to produce brandable name ideas and instantly see which ones have an available domain, then run the trademark and registry checks on your favourites.

Are free business name generators reliable for availability?

They vary. Nametastic checks domain availability live against registrars, so its "available" results are real-time — but always confirm trademarks and state registration separately before you file.

How to Check if a Business Name Is Available

A step-by-step guide to confirming your business name is free to use — across domains, trademarks, social media, and your state's registry — before you commit. Try ideas in the generator below.

Why checking availability matters

Picking a name you love is only half the job. Before you print business cards or file paperwork, you need to know the name is actually free to use — as a domain, a trademark, a registered business, and a social handle. Skipping these checks can mean an expensive rebrand or a legal dispute later. The good news: you can clear most of it in a few minutes.

5 steps to check business name availability

1. Shortlist a few name candidates

Never bet everything on a single name. Generate a shortlist of 5–10 strong options so that when one is taken, you have backups ready. Nametastic's AI generator produces brandable, on-concept ideas in seconds — describe your business and pick the ones that resonate.

2. Check domain availability

The fastest first filter is the domain. If the .com (or a strong .io/.co/.ai) is gone, many founders move on. Nametastic checks domain availability live against registrars as it generates, so you instantly see which names you can actually own — no separate lookup required.

3. Search your state business registry

Most US states let you search registered business entities through the Secretary of State website. Confirm no existing LLC or corporation in your state already holds the name, since registries block duplicates. Check the states where you'll actually operate.

4. Run a trademark search

A free domain does not mean the name is legally clear. Search the USPTO trademark database (TESS) for identical or confusingly similar marks in your industry. A registered trademark can force you to rebrand even if you got the domain first.

5. Claim matching social handles

Finally, check that the handles you want are open on the platforms that matter to you — Instagram, X, TikTok, LinkedIn, YouTube. Consistent handles make your brand easier to find. If the exact handle is taken, a close variant is usually fine.

Quick availability checklist

A name is safe to use when all four are clear:

Domain — an available .com or strong alternative TLD
State registry — no existing LLC/corporation with the name
Trademark — no conflicting mark in your industry (USPTO)
Social handles — your key platforms are open

Describe your business, and it generates brandable names while checking domain availability live — so every suggestion you see is one you can actually register.
