Results are based on public DNS records and are a quick guide only. Always confirm availability with a domain registrar before buying, since a domain can still be reserved or restricted even with no DNS record.

Frequently asked questions
Is “available” a guarantee I can register the domain?
No. This tool checks DNS records for instant feedback. Some domains may be reserved or parked without DNS records. Always verify ownership rules with official registries like ICANN or your preferred domain registrar before buying.
What if my domain name is taken?
If your primary choice is taken, try alternative extensions like .io, .dev, or .app, or test short variations using our instant domain checker.
