WHOIS Lookup — Check Domain Registration Details
WHOIS lookup for any domain: registrar, registration and expiry dates, and name servers, where the registry publishes them. Note many fields are privacy-redacted.
WHOIS is the public registration record behind a domain. This tool queries it and reports the details the registry chooses to expose — the go-to check before buying a domain, verifying who a site belongs to, or seeing how soon a registration lapses.
What WHOIS usually shows
- Registrar — the company the domain is registered through
- Creation, last-updated, and expiry dates
- Status codes such as clientTransferProhibited (a transfer lock) or pendingDelete
- The name servers the domain uses
- Registrant contact fields — where they aren't redacted
Why so much is redacted
Privacy protection is now the norm. Registrars routinely replace personal contact details with a privacy proxy, and GDPR led many registries to redact registrant data entirely — so 'REDACTED FOR PRIVACY' is expected, not an error.
The dates and name servers, though, come straight from the registry and stay reliable. That's why WHOIS is still excellent for confirming a domain's age and renewal timing even when the owner's identity is hidden.
Frequently asked questions
- Why does one domain return lots of detail and another almost none?
- Different registries publish WHOIS differently — some top-level domains expose more, others very little — and each registrar layers its own privacy handling on top. The amount you see depends on those policies, not on the tool.
- Can I use WHOIS to check if a domain is available?
- Indirectly. A domain with no registration record is likely unregistered, but to actually buy it you'll still go through a registrar, which runs its own real-time availability check.
