Domain Registrar Lookup

Find out which company a domain is registered with. Enter a name and this tool reads the live registry record and shows the registrar, its IANA ID, the WHOIS server, the transfer-lock status and the name servers. It is the quick way to answer "who do I contact to manage or transfer this domain?" — useful when you have lost track of where a name lives, or are planning a transfer.

How to use the Domain Registrar Lookup

Enter a domain and press Find registrar. The tool looks up the registry record and reports:

• The registrar — the accredited company that manages the registration (for example GoDaddy, Namecheap, Cloudflare, Hostinger).
• The IANA registrar ID, a unique number assigned to each accredited registrar, which removes any ambiguity between similarly named companies.
• The WHOIS server that answered, the registrar URL where published, and the transfer-lock status.
• The name servers, which often reveal where DNS is actually run (which can differ from the registrar, for example a domain registered at GoDaddy but using Cloudflare DNS).

This distinguishes the registrar (who you renew and transfer with) from the DNS host (who answers DNS queries), which are frequently different services.

What a domain registrar is

A registrar is an ICANN-accredited company authorised to register domain names on behalf of customers. When you "buy" a domain, you are registering it through a registrar, who records the registration with the relevant registry (the organisation that operates a TLD, such as Verisign for .com). The registrar is who you log in to for renewals, DNS changes and transfers.

Knowing the registrar matters in several practical situations:

• Transfers — to move a domain you unlock it at the current registrar and request an authorization (EPP) code from them. You must know who they are to start.
• Lost access — when you cannot remember where a domain is registered (common after years or staff changes), the registrar tells you which account to recover.
• Abuse and disputes — registrars handle abuse reports and are the contact point for many domain disputes.
• Consolidation — teams managing many domains often want them all at one registrar; this shows which names are still elsewhere.

The record also includes the IANA registrar ID, a stable numeric identifier that uniquely names the registrar even when brands rename or resell, plus EPP status codes like clientTransferProhibited that show whether a transfer lock is in place. Remember that the registrar and the name server host can be different companies: a domain can be registered with one provider while its DNS is run by another, so check both fields.

Common use cases

• Starting a domain transfer — identify the current registrar so you can request the auth code and move the name.
• Recovering a forgotten domain — find out which registrar account a long-held domain lives in.
• Portfolio consolidation — see which of your domains are still scattered across different registrars.
• Filing an abuse report — find the registrar responsible for a domain you need to report.
• Competitive and vendor research — see which registrar and DNS host a given organisation uses.

Registrar vs registry vs DNS host

• Registry — the operator of an entire TLD (Verisign runs .com and .net, PIR runs .org). You never deal with them directly; registrars do.
• Registrar — the accredited company you register and renew a domain through (GoDaddy, Namecheap, Cloudflare, Hostinger). This is what the tool reports, and who you contact for transfers.
• DNS host / name servers — whoever runs the authoritative DNS for the domain. Often the registrar, but frequently a separate service (for example Cloudflare DNS on a domain registered elsewhere). The name servers field reveals this.

A domain can therefore be registered at one company, have DNS run by a second, and be hosted on a third. Reading the registrar and name servers together tells you who controls what.
