What Is a Registrar

Learn what a domain registrar is, how registration differs from hosting and DNS, renewals, transfers, and locks.

By CheckDomainHealth Editorial Team Reviewed by Dionis Ceban Updated Jun 28, 2026 5 min read Beginner

Introduction

You buy and renew domains through a registrar accredited with the domain registry (for .com, .org, country TLDs, etc.).

Hosting serves website files. DNS hosting serves DNS records. Registrar holds the registration itself — three roles often confused.

Quick answer

Quick answer

A registrar is the company where your domain is registered — where you pay renewal fees, unlock transfers, update nameservers and manage registration status. Registrar is not the same as web hosting or DNS hosting, though some companies offer all three.

What it means

The registrar maintains your domain lease with the registry, handles renewals, transfers, locks and nameserver delegation at the registry level.

  • Registration and renewal billing
  • Nameserver updates at registry
  • Transfer lock and EPP/Auth codes
  • WHOIS/RDAP registrant data (may be private)
  • Domain status flags (hold, redemption, etc.)
  • Separate from website hosting and email hosting

Where you see this:

  • Renewing domains before expiry
  • Transferring domains between registrars
  • Updating nameservers to point DNS elsewhere
  • Unlocking domains for transfer or fixing holds

Why this matters

Why this matters

Logging into the wrong company blocks renewals and transfers. Domain expiry at the registrar takes the entire domain offline regardless of hosting quality.

How to check it

  1. Run WHOIS Lookup to see current registrar name.
  2. Log in to that registrar account (or find billing email).
  3. Check expiry date and auto-renew status.
  4. Verify nameserver settings match your DNS provider.
  5. Confirm contact email is current for renewal notices.

Common mistakes

Confusing registrar with hosting provider

High

Paid hosting company but domain registered elsewhere.

Next step: Identify registrar via WHOIS; renew at registrar.

Changing hosting but not registrar nameservers

Medium

Website moved but DNS still points to old infrastructure.

Next step: Update nameservers or DNS at authoritative provider.

Outdated contact email on registration

High

Renewal notices missed; domain expires unexpectedly.

Next step: Update registrant contact in registrar portal.

Domain expires due to payment failure

High

Auto-renew card expired or invoice unpaid.

Next step: Renew during grace period; check redemption fees if late.

Transfer lock confusion

Medium

Transfer blocked by lock or recent registration period.

Next step: Disable transfer lock at registrar when transfer intended.

Example

Registrar vs hosting vs DNS 
Registrar:  where example.com is registered (WHOIS)
DNS host:   where A/MX/TXT records live (NS records)
Web host:   where website files run (A record target)

Frequently asked questions

Is GoDaddy always my registrar if my site is hosted there?

Not necessarily. Hosting and registration can be separate. Check WHOIS for the actual registrar.

Can I move DNS without changing registrar?

Yes. Update nameservers at the registrar to point to another DNS provider.

What is an EPP or Auth code?

A transfer password from the registrar required to move a domain to another registrar.

What happens if my domain expires?

Site and email stop after grace periods. Recovery may require redemption fees or may be impossible if deleted.
