How To Find Out Who Owns A Website Or Domain

The quickest way to find out who owns a website is to look up its domain in a registration data (WHOIS/RDAP) lookup. The result may show the owner's name and contact details, or the details of a privacy service if the owner has hidden them. If the owner is hidden, there are still legitimate ways to reach them.

This guide covers the lookup, what the result means, and what to do when the data is not public. It also covers the common case of wanting to buy a domain that someone else already owns.

Why people look up a site's owner

Checking a business: confirming that a shop or service is who it says it is before you pay.
Buying the domain: your ideal name is taken and you want to make an offer. See how domain sales work from the seller's side.
Reporting abuse: a phishing or scam site needs to be reported to the right company.
Business contact: partnerships, link requests, or a legal notice.

Step 1: look up the domain

Registration data is held by the registry and the registrar, and you can query it through a lookup tool. Two good options:

Our WHOIS lookup. Enter the domain and read the contact, name server and DNS information it shows.
ICANN's registration data lookup tool. Enter the domain and press Lookup.

ICANN's tool uses RDAP, which it describes as the replacement for the older WHOIS (port 43) protocol. Results come directly from registries and registrars. Since 28 January 2025 most generic TLD registries and registrars are no longer required to run WHOIS services (except .com, .name and .post), so RDAP is now the standard way to get the data. For more tools, see our overview of WHOIS domain lookup tools.

Step 2: read the result

A typical record shows the registrar, the creation date, the expiry date and the name servers. It may also show the registrant, meaning the person or organisation that registered the domain. Even with no personal details, you learn:

The registrar, which is the company that can forward a message or handle a complaint. See where a domain is registered.
The age of the domain, which helps judge a business or a possible scam site.
The expiry date, useful if you hope to register the name when it is released. Read the domain life cycle for what happens next, and watch our expiring soon list.

Step 3: if the owner's details are hidden

Many owners use a privacy or proxy service, and registrars may also withhold personal data. In that case the record shows the service's details, or a redacted field. ICANN notes that people with a legitimate interest in nonpublic data, such as law enforcement or intellectual property professionals, can use its Registration Data Request Service (RDRS), or contact the sponsoring registrar to ask about its disclosure process. Ordinary users have simpler options first:

Use the website itself. Check the contact page, the footer, the imprint or terms of service, which often name the company.
Use the privacy service's contact route. Many forward messages to the owner. The service's name appears in the record.
Check social media for accounts linked from the site or using the same name.
Look up the domain's hosting with our guide to finding where a domain is hosted. For abuse reports, the host and registrar can both be contacted.
Use a domain broker if you want to buy the name. A broker contacts the owner for you and negotiates. Brokers charge a fee or commission, so compare terms.

Do not try to unmask owners by other means, and use any personal data you find only for lawful purposes. ICANN's lookup terms require this.

Wanting to buy a domain that is taken

If you found the owner and want the name:

Check whether the site is actively used. A parked or empty page often means the owner is open to offers.
Note the expiry date. If the owner lets it lapse, you may be able to register it yourself. Our expired domains list shows names that are available to register.
Send a short, polite message with a specific offer. Be prepared to negotiate.
Use an escrow service for payment and complete the move through a registrar transfer. See how domain ownership transfers work.

FAQ

Is it legal to look up who owns a website?

Yes, registration data lookups are public tools intended for this. Use the data only for lawful purposes, as ICANN's terms state.

Why does the result show a company I do not recognise?

It is probably a privacy service or the registrar. The real owner is not shown.

Does the registrar own the site?

No. The registrar manages the registration. The registrant is the owner, and the web host stores the site's files.

Can I find the owner of a domain that is available?

No. If nobody has registered it, there is no owner. You can register it yourself.
