3 free checks per day. No signup needed.
How to check if a domain is available
- 1Type the domain you want (for example, acme.io) and run the check.
- 2We query the registry live, the same source a registrar uses, not a cached list.
- 3You get a clear available or taken answer, and if it's taken, who holds it and when it expires.
How domain availability is determined
A domain is available when its registry holds no record for it at all. This checker queries that registry directly through RDAP and WHOIS, so the answer reflects the real, current state, not a cached guess. If a domain is already owned, you also see the registrar and expiry date instead of a bare "taken".
Check availability across extensions
The exact .com is often taken, but the same name is frequently free on .io,.co, .app, or .dev. Check a few extensions before you commit to a name, and use the Short Domain Name Generator if you need fresh ideas.
Frequently asked
How do I check if a domain is available?
Enter the domain above. This tool queries the registry through RDAP, or WHOIS for older registries, and reports it available when there's no record for it at all.
The domain shows as available, why can't I register it anywhere?
A registry record can lag a few minutes behind a very recent registration, and some registrars briefly reserve premium or recently expired names. Try again in a few minutes or check a second registrar.
Can I check several domains at once?
Yes. To check many domains in one pass, paste a list into the Bulk Domain Availability Checker, which handles up to 10 at a time. This page is best for checking a single name and its extensions in detail.
Is a domain really free if it shows as available?
Availability is checked live at the moment you search, so an available result is accurate right then. But domains can be registered by anyone at any second, so if you find a name you want, register it promptly before someone else does.
What if the .com is taken?
The exact .com is often gone, but the same name is frequently available on newer extensions like .io, .co, .app, or .dev. Check a few extensions, and if nothing fits, generate fresh short ideas with our Short Domain Name Generator.
