Type any domain and instantly see whether it can still be registered.
This check uses public DNS & RDAP registry lookups performed live from your browser. Results are a strong indicator but registrars remain the final authority for registration.
The Domain Availability Checker gives you an instant read on whether a domain name is already registered or still open for purchase. Instead of opening a registrar's cart flow just to find out a name is taken, you can type it here and get a live answer in a couple of seconds, straight from public DNS resolvers and the RDAP registry network — the same data registrars themselves consult.
When you click "Check Availability", your browser sends two lightweight, read-only queries. The first asks Google's public DNS-over-HTTPS resolver whether the domain currently has an A record — if it does, something is being hosted on it right now, which almost always means it's registered. The second query talks to the RDAP (Registration Data Access Protocol) layer that replaced the older WHOIS protocol for most registries, and asks whether a registration object exists for that exact name. Combining both signals gives a more reliable picture than either check alone, because a domain can be registered but not yet pointed at a live website.
Anyone naming a new project, product, or company runs into the same wall: the .com you want is probably taken. Checking availability quickly, for many name variations in a row, saves the frustration of adding items to a cart only to be told "unavailable" at checkout. It's equally useful for trademark and brand teams doing a first-pass sweep across a list of spelling variants, ccTLDs, or new gTLDs before commissioning a full legal clearance search.
A green "Likely Available" badge means neither DNS nor RDAP could find an active record — treat this as a strong signal, not a 100% guarantee, since some registries rate-limit or restrict RDAP responses. A red "Registered" badge means the domain is actively resolving or has a confirmed registry record, so it's not available through a standard purchase flow. If the tool can't reach the lookup services (rare, but possible on slow connections or with unusual TLDs), it will tell you rather than guessing.
No. It only checks status. To register an available name you'll still need to complete the purchase through an ICANN-accredited registrar.
Some registrars mark domains as premium, reserved, or in a redemption grace period after expiry. These states can differ from a plain DNS/RDAP check, so always confirm at checkout.
Yes, most modern gTLDs and many ccTLDs support RDAP. A handful of smaller ccTLD registries don't publish RDAP data, in which case the result will lean on the DNS check alone.
The domain you type is sent only to the public DNS and RDAP services needed to answer the question — we do not log or store your searches on our servers.
Typing an unregistered domain into a browser just returns a generic "can't be reached" page with no useful detail. This tool explicitly tells you the registration status and shows you the evidence behind that answer.
