Look up WHOIS domain registration details online free - no login. Enter any domain name to instantly see the registrar, registration date, expiry date, and name servers.
WHOIS data is essential for due diligence before buying a domain, checking competitor domain age, verifying that a domain is registered to the organization it claims to represent, and monitoring domain expiry for domains you are watching.
Enter any domain name to see its registration date, expiry date, registrar, and owner details (where not privacy-protected). Uses public RDAP records - the modern replacement for traditional WHOIS.
Check domain registration date before buying an aged domain, verify domain expiry to time a purchase or backorder, check if a domain is available before making a website, investigate who owns a domain before sending outreach, verify a company's domain registration details for due diligence, and monitor competitors' domain renewal status.
The most common question is why WHOIS shows a privacy service instead of owner details. Most registrars offer WHOIS privacy protection - replacing personal contact information with a privacy service's address. The registrar name, registration date, and expiry date are always visible regardless.

Common questions about this tool and how to use it.
A WHOIS lookup returns the registrant contact information associated with a domain registration. Many registrars now offer WHOIS privacy protection - replacing personal contact details with a privacy service address. When privacy is enabled, you will see the registrar's information and the privacy service, but not the individual owner's name or address.
A standard WHOIS record includes: registrar name (e.g., GoDaddy, Namecheap), registration date, expiry date, nameservers, and registrant contact information (name, organization, email, phone - unless privacy protection is enabled). RDAP (the modern replacement for WHOIS) provides the same data in a structured JSON format.
Most registrars offer WHOIS privacy protection as a free or paid add-on. It replaces the registrant's personal information with the privacy service's contact details to prevent spam, identity theft, and automated data harvesting. ICANN rules require registrars to provide a way to contact the domain owner even when privacy is enabled, typically via an email forwarding form.
Yes - the expiry date is always visible in WHOIS records, even when privacy protection is enabled. This is public information that registrars are required to display. Monitoring a domain's expiry date is useful for identifying domains that may become available for registration, or for checking whether your own domains need renewal.
WHOIS is the original domain lookup protocol (RFC 3912) used since 1982 - it returns plain text responses and has inconsistent formatting between registrars. RDAP (Registration Data Access Protocol, RFC 7480) is the modern replacement - it returns structured JSON, supports HTTPS, and provides more consistent data across registrars. Most modern WHOIS lookup tools use RDAP under the hood.
