Domain Availability Checker
Enter a domain to see whether it's already registered or looks available to register.
Overview
Before registering a new domain, it helps to quickly check whether someone else already holds it. This tool queries RDAP — the same registration data the WHOIS Lookup tool uses — and reports whether a registration record exists.
A missing RDAP record usually means a domain is unregistered, but it isn't a guarantee: always confirm with a registrar's own registration flow before assuming a domain is free, since a small number of registries redact rather than omit records for domains that are actually taken.
Examples
Checking availability
example.com
example.com is NOT available — it is already registered.
How It Works
- Enter a domain name, e.g. example.com.
- Complete the verification check if shown.
- Click Check Availability to query the domain's registry via RDAP.
- Review whether the domain appears registered or available.
Use Cases
Picking a domain for a new project
Quickly rule out domain names that are already taken before deciding what to register.
Confirming a domain lapsed
Check whether a domain you were watching has become available again.
Tips
- An "available" result here is a strong signal, not a guarantee — always confirm through a registrar's own registration flow before relying on it, since RDAP silence can also mean a registry is redacting the record.
FAQ
The domain you enter is sent to our server, which queries the domain's registry via RDAP on your behalf — nothing else about you is sent or stored.
This lookup queries external registry infrastructure on your behalf, so a quick bot check helps keep the tool available and responsive for everyone.
No — it only checks whether a domain appears registered. Registering a domain has to be done through a domain registrar.
