How to find who owns a domain

Identify the registrant of any domain in seconds.

1Step 1

Enter the domain name

Type the domain you want to investigate into the search box. Ownership details are tied to the root domain — strip any subdomain or path first (use example.com, not blog.example.com).

2Step 2

FetchWhois queries registrant records

We query the RDAP server for the domain's TLD and follow the related link to the registrar RDAP server for richer entity data, including registrant, administrative and technical contacts.

3Step 3

Review owner and contact details

Where the registrar makes them public, you will see the registrant's name, organization, email, phone and address. If details are redacted under GDPR, the registrar's abuse contact is shown as an alternative way to reach the domain owner.

How to find who owns a domain name

A domain owner lookup queries the WHOIS or RDAP record for a domain and returns the registrant entity — the individual or organization that registered the domain. A full owner lookup typically shows registrant name, organization, email, phone and postal address, though how much is visible depends on the registrar's privacy practices and applicable data protection law.

Since ICANN began enforcing GDPR compliance in 2018, most registrars redact personal registrant contact details from public WHOIS and RDAP responses. When you run a domain owner lookup today, personal details like name, email and phone are often hidden. The registrar's abuse email and the domain's own contact form remain accessible and are the recommended channels for reaching a domain owner whose details are redacted.

FetchWhois performs owner lookups using the RDAP protocol, querying the authoritative registry and registrar servers directly. This means results reflect the actual live registration record — not a stale snapshot from a third-party database. If ownership has changed recently, an RDAP-based lookup will show the current owner faster than tools that rely on cached data.
