How to Find Out Who Owns a Domain Name
Run the domain through ICANN Lookup (lookup.icann.org), which uses RDAP, the protocol that replaced WHOIS as the required service for generic domains. You'll see the registrar, creation and expiry dates, and name servers. The owner's name is usually redacted for privacy, so contact them through the registrar's relay or web form, or check the website itself and its archived history.
Free methods, step by step
- Run ICANN Lookup. Go to lookup.icann.org, type the domain into Enter a domain name or an Internet number resource and select Lookup. The tool uses RDAP. You'll see the registrar, the domain status codes, the creation, update and expiry dates, and the name servers.
- Read the registrant section. For most personal domains it says the data is redacted, or names a privacy or proxy service. Companies sometimes appear by name.
- Use the registrar's contact route. Registrars usually offer a relay email address or web form so you can reach the registrant without seeing their details. Follow the registrar link in the result.
- For .ca domains, use CIRA. On CIRA's WHOIS page, enter the domain in Find a .CA domain. Corporations' registrant details are shown. Individuals' details aren't, and CIRA's Message Delivery form sends a message to the registrant for you.
- For .uk domains, use Nominet's RDAP. Nominet is retiring its WHOIS. A registrant's name and address are shown only with their consent.
- Read the website and its history. Look at the About, Contact, Imprint, Privacy and Terms pages. Then open the site in the Wayback Machine; older versions sometimes named the operator.
Example walkthrough
Who runs a site selling your photos?
Illustrative example. The names, numbers and details are invented placeholders, not a real person or case.
Your photos appear on "example-prints.com". ICANN Lookup shows a registrar, a creation date eight months ago and a redacted registrant. The site's terms page names no company. You use the registrar's abuse or contact form, which is the right channel for copyright problems. You also contact the site's host, which you can identify from the name servers or IP. Neither route needs the owner's name.
WHOIS, RDAP and redaction
RDAP is the newer protocol for registration data. According to ICANN, all gTLD registries and registrars must provide RDAP, and as of 28 January 2025 they're no longer required to run WHOIS, except for .com, .name and .post. Since GDPR took effect in 2018, most registrars redact personal registrant data by default, so the owner of a personal site is rarely visible.
If you want the domain
Email an offer through the relay, use a reputable broker, or watch the expiry date. If someone is using a domain that infringes your trademark, the UDRP dispute process exists for that. It's not a way to take a domain you'd just like to own.
Common dead ends, and why they fail
- Old WHOIS sites. Many still work but show the same redacted data, or out-of-date copies of it.
- "Historical WHOIS" from before GDPR. Some paid services sell pre-2018 records. They may show who owned a domain years ago, not today.
- Asking the registrar to reveal the owner. Registrars generally won't, except to law enforcement or under legal process. They will forward messages.
- Privacy services. The registrant shown is the proxy company. Contact goes through it.
What if nothing works
- Use the registrar's abuse contact for illegal content, phishing or malware. ICANN requires accredited registrars to have one.
- For trademark misuse, the UDRP dispute process exists. A lawyer can advise.
- If you just want to buy the domain, watch its expiry date, or make an offer through the relay or a broker.
What people search for on this topic
The suggestions are tool words: lookup, search, check, checker, tool. GoDaddy is the only registrar named. UK and Australia variants appear.
Two suggestions are noise from a different meaning ("domain expansion in jjk", an anime reference). The question form adds "who owns a website", which is the same need phrased by people who don't know the word "domain".
None of the suggestions mention RDAP, so pages should use the familiar words (WHOIS, lookup) and explain RDAP in passing.
Google's top suggestions for who owns a domain (US, captured October 12, 2026):
- who owns a domain
- who owns a domain lookup
- who owns a domain name
- who owns a domain search
- who owns a domain check

FAQ
Is WHOIS still a thing?
For generic domains, RDAP has replaced it as the required service, though many tools still call any lookup a WHOIS search.
Why is the owner hidden?
Most registrars redact personal data by default for privacy, and many owners also use a privacy service.
Can I find the real owner behind a privacy service?
Usually only through a legal process, such as a court order or a trademark dispute.
How do I contact a domain owner?
Use the registrar's relay email or contact form, or the contact details on the website itself.
What is RDAP?
The Registration Data Access Protocol, the replacement for WHOIS. ICANN's lookup tool uses it, and it gives structured data in a standard format.
Where do I report a phishing or malware domain?
To the registrar's abuse contact. ICANN's Registrar Accreditation Agreement requires accredited registrars to publish an abuse email address or web form and to investigate reports. The registrar is named in the ICANN Lookup result.
How do I find out how old a domain is?
ICANN Lookup shows the creation date along with the expiry and last-updated dates. A shop or charity whose domain was registered a few weeks ago deserves extra checks.
How do I contact the owner of a .ca domain whose details are hidden?
Use CIRA's online Message Delivery form, which sends a message to the registrant for you without revealing their identity.
