How to look up a domain's registrar

Registrar name, IANA ID and abuse contact from the live RDAP record.

1Step 1

Enter the domain name

Type the domain name into the search box above. The registrar record is tied to the apex domain, so use example.com rather than www.example.com.

2Step 2

FetchWhois identifies the registrar entity

We query the RDAP server and parse the registrar entity from the response — including the registrar's full name, IANA registrar ID, and nested abuse contact details.

3Step 3

View registrar name and contact details

The registrar's name and IANA ID appear at the top of the results. Scroll down to the registrar entity card to see the abuse email, abuse phone and a link to the registrar's website.

What is a domain registrar and how do you identify one?

A domain registrar is an ICANN-accredited company authorized to sell and manage domain name registrations on behalf of registrants. Every registered domain has exactly one registrar — the company responsible for maintaining the registration record in the registry and providing renewal, transfer and DNS management services to the domain owner. ICANN assigns each accredited registrar a unique IANA registrar ID number, which is included in every WHOIS and RDAP record.

Knowing a domain's registrar is useful for several reasons: if you want to transfer the domain to a different registrar, you need to initiate the process from the current registrar's control panel. If the domain is associated with spam or abuse, the registrar is the correct party to contact. If you are trying to purchase a domain from its owner, the registrar can facilitate an escrow transfer.

FetchWhois reads the registrar entity directly from the authoritative RDAP record. The IANA registrar ID shown is the official identifier — you can verify it against ICANN's public registrar database at registrar-report.icann.org.
