Use ICANN’s Registration Data Lookup Tool to check a domain’s current public registration record. Enter the domain, then review its registrar, any publicly listed registrant details, and the dates shown. The result may not reveal a person’s identity: registration data can be redacted or unavailable.
Check a domain’s registration record
- Open ICANN’s Registration Data Lookup Tool and enter the domain name. ICANN says the service queries current registration data in real time from registries and registrars using RDAP. If information for a domain is unavailable through RDAP, the tool may fall back to the relevant generic top-level domain (gTLD) registry’s WHOIS service.
- Find the registrar field. It identifies the service provider associated with the domain’s registration; it does not identify the person or organization that registered it.
- Review the registrant and contact fields. If details are redacted, withheld, or absent, the public result does not establish the registrant’s identity.
- Look for the Dates section. It may include the domain’s creation, expiry, and last-updated dates. Which fields appear can vary, and ICANN says dates are supplied by the registrar.
ICANN’s lookup FAQ explains what fields may appear and why results vary.

Registrant and registrar are not the same
The registrant is the person or entity that registers a domain. The registrar is the provider the registrant contracts with and uses to manage domain settings. ICANN explains this relationship in its information for domain name registrants.

What the expiry date does—and does not—tell you
An expiry date is a date in the registration record. It does not, by itself, establish when a domain will become available for someone else to register. Do not assume a domain can be acquired immediately on the date shown.
Check that you are reading the expiry field rather than the creation or last-updated date. If no expiry date appears, the public result has not supplied one.

Why ownership details may be hidden
Public registration results do not always show personal contact information. What is disclosed varies with applicable law and policy, and with registrar and registry practices. A missing or privacy-protected field should be treated as unavailable in the public record—not as proof that the domain has no registrant.

If you need nonpublic registration data
Start with the public lookup. If it does not provide information you legitimately need, ICANN directs people seeking nonpublic gTLD data to the Registration Data Request Service (RDRS) for participating registrars, or to the sponsoring registrar’s disclosure process. A request route is not a guarantee that personal information will be released.

ICANN announced that RDAP became the definitive source for gTLD registration information on 28 January 2025, replacing the sunsetted WHOIS services for those domains. Its RDAP and WHOIS transition notice describes the change and the disclosure routes for nonpublic data. This gTLD guidance should not be assumed to apply identically to every country-code domain; lookup services and data availability can differ by TLD.
