How to Find Out Who Owned a Domain Before

Run a WHOIS or RDAP lookup first. Even when the owner is hidden, the record usually shows the registrant's state or province and country, and sometimes the organization. If an organization is listed, you have your current owner.

Note the creation date too. Selling a domain or moving it to another registrar keeps that date. Letting it expire does not. A creation date that's much newer than the domain's oldest records means the current owner registered it after it was dropped, and everyone before them owned an earlier registration.

This is the most direct source. Until 2018, WHOIS for .com, .net, .org and most other generic domains published the registrant's name, organization, email, address and phone number, unless the owner paid for a privacy service. Archives that captured those records still have them.

A WHOIS history lookup on who.is shows how many records we hold for a domain and the years they cover. Our archive starts in 2007. The full report lists each record's registrant, admin, tech and billing contacts with the date we captured it, plus a timeline of what changed.

Look at the admin and tech contacts as well as the registrant. On older records these often name a person even when the registrant is a company.

Not every change in the records is a new owner.

• A new registrant name or organization is the clearest sign of a sale.
• A new registrar on its own usually isn't. Owners move domains between registrars for price or convenience.
• A privacy service appearing may just be the same owner turning on privacy. Check whether anything else changed at the same time, such as the nameservers.
• A gap, then a new creation date means the domain was dropped and someone new registered it.
• New nameservers often come with a new owner or a new host. On their own they don't prove a sale.

The Wayback Machine keeps copies of many sites back to 1996. Check the About and Contact pages and the copyright line in the footer. Sites run from Germany and Austria usually have an Impressum page, which by law names the person or company responsible.

• Certificate logs. Every publicly trusted TLS certificate is logged, and crt.sh lets you search them by domain. Organization-validated certificates include the company's name, so an old one can identify a past owner.
• Search engines. Search for the domain in quotes. Old press releases, forum posts and directory listings often mention who ran it.
• Business registries. Once you have a company name, a state business search in the US or Companies House in the UK can tell you who was behind it.

Past records won't always lead you to today's owner. If you need to reach them:

• Use the email address or contact form listed in the WHOIS record. When the owner is hidden, these forward to them. They don't have to reply.
• If you have a legitimate reason, such as a legal claim or a security investigation, ask for the details through ICANN's Registration Data Request Service. Participating registrars decide each request.
• For a trademark dispute, a UDRP complaint gets you the registrant's details as part of the process. A court order works too.

who.is shows the public record only. We can't see or share details a registrar has hidden.

Domains under country codes, such as .uk, .de or .fr, follow their own registry's rules rather than ICANN's. Several of these registries hid individuals' details well before 2018, so past records for them may not name an owner either. Companies are more often listed.
