A domain registrar is the ICANN-accredited company you lease a domain name through. Learn the registry, registrar, reseller and registrant chain — and how to choose one.

A domain registrar is the company you register a domain name through. It is the shopfront of the domain system: you pay the registrar, and the registrar records your claim to the name with the registry that runs the extension. If you are still fuzzy on the name itself, start with our guide to what is a domain name — then come back here, because the registrar is the company that sells you the right to use that name, year after year.

This guide explains the whole chain in plain English: what a registrar does, how it differs from a registry, a reseller and your web host, how to pick a good one, and how to find out which registrar already holds your domain.

What is a domain registrar?

A domain registrar is an ICANN-accredited company that manages the reservation of internet domain names on behalf of individuals and businesses. To sell domains, a company must be accredited by ICANN (the Internet Corporation for Assigned Names and Numbers) for generic extensions such as .com, or by the national registry for a country extension such as .uk or .de. As of March 2024, about 2,800 registrars were accredited by ICANN, according to Wikipedia.

When you "buy" a domain, you are technically leasing it. The registry that runs the extension owns the extension itself — Verisign runs .com — and the registrar is the authorized intermediary that leases you the right to use one name inside it, usually for one to ten years at a time. Keep paying the renewal, and the name stays yours to use. Stop paying, and it eventually goes back on the market for anyone else to claim.

The four roles in every domain name

Four different parties are involved in every domain name you type into a browser. Most confusion about registrars comes from mixing them up, so here is the whole chain in one place:

The chain works like this. ICANN grants a registry the right to run an extension. The registry keeps the master list of every name registered under that extension. The registrar takes your order, checks the name is free, pays the registry a wholesale fee, and records the name in your name. You never deal with the registry directly — and, as IONOS puts it, the registrar is the commercial intermediary between the registry and you.

GoDaddy is the largest registrar, managing over 50 million .com domains, according to Wikipedia. But size is not the same as suitability, and the rest of this guide is about choosing well rather than choosing big.

What does a domain registrar do for you?

A registrar does more than take your money once a year. These are the jobs it handles on your behalf:

• Availability check. When you search for a name, the registrar queries the registry to confirm nobody else holds it.
• Registration. It submits your claim to the registry and records your contact details as the registrant.
• DNS and nameservers. It lets you point the domain at your website and email by setting nameservers — the records that tell the internet where your site lives. If you want the detail, our guide to what is DNS propagation explains why those changes take time to spread.
• Renewal and reminders. It sends renewal reminders, and most registrars offer auto-renewal so a lapsed card does not cost you the domain.
• WHOIS privacy. ICANN requires contact details on every registration, but a good registrar replaces yours with its own details in the public record, free of charge.
• Transfers. It handles moving a domain in from, or out to, another registrar when you switch.

Many registrars also sell add-ons — hosting, email, SSL certificates, website builders — but those are separate services, and buying them from the same company is a convenience, not a requirement.

Domain registrar vs registry: what is the difference?

This is the question that causes the most confusion, so here is the cleanest way to keep the two apart:

Think of it like a car dealership, an analogy CyberOptik uses: the registry manufactures the product, the registrar is the dealership that sells it to you. The dealership does not own the factory, and you do not buy a car from the factory — you buy it from the dealer. The same split applies here, and it is why your registrar's price and service matter even though the underlying registry is the same for everyone.

Is a domain registrar the same as web hosting?

No — and keeping the two separate in your head is the single most useful thing in this guide. A registrar reserves your domain name. A web host stores your website's files and serves them to visitors. They are different services, run by different systems, and they do not have to come from the same company.

Many companies sell both, which is where the confusion starts. Buying them together is convenient, but it is often better to keep them separate: if your host has an outage, has a billing dispute, or simply stops being the right host, a domain held elsewhere keeps working and moves with you. Our guide to how to move a website to a new host without downtime walks through exactly that move — and it is much simpler when your domain is not locked inside your hosting account.

The practical rule: your registrar holds the name, your host holds the files, and the nameserver settings at your registrar are the bridge between the two. Change the nameservers, and the same domain points at a new host — the name itself never moves.

What is a domain reseller?

A reseller is a company that sells domains through a registrar's system under its own brand, without being an ICANN-accredited registrar itself. Many web designers, agencies and hosting companies are resellers: you buy the domain from them, they register it through their partner registrar, and the registrar is the company that actually holds the registration at the registry.

For most day-to-day purposes, a reseller works fine — renewals and DNS changes go through the reseller's dashboard. The catch is that if something goes wrong, the reseller is a middleman: it cannot change the registry record itself, only ask its registrar to. When you look a domain up in ICANN Lookup and the registrar field names a company you have never heard of, that is usually why — you bought from a reseller, and the listed company is the registrar behind it. Google Workspace Help notes that the reseller entry, when there is one, appears in the raw registry response further down the lookup page.

How to choose a domain registrar

There are about 2,800 ICANN-accredited registrars, so the choice is not which registrar exists — it is which one treats you fairly. Judge them on the renewal price, not the first-year price, and on these checks:

• Renewal price, not the first-year price. First-year offers of $1 or $2 are common, but the renewal is the price you will pay every year after. A typical .com costs around $10 to $12 a year to renew, according to Kinsta, and Wikipedia puts the usual retail range for a simple .com registration at about $9.70 to $35 a year (figures as of 2023). If a registrar's renewal price is far above that range, the cheap first year is not a bargain.
• Free WHOIS privacy. ICANN requires contact details on every domain, but the best registrars hide yours behind their own details at no extra cost. Paying yearly for privacy is a sign to look elsewhere.
• Full DNS control. You should be able to change nameservers and DNS records yourself, without a support ticket. If the dashboard hides those settings, walk away.
• Clear transfer rules. A good registrar lets you leave: it gives you the transfer authorization code quickly and charges no exit fee. Watch for registrars that make you call support to unlock a domain.
• Auto-renewal and reminders. Auto-renewal plus email reminders before expiry is the minimum. An expired domain can be expensive or impossible to recover, so this is not a nice-to-have.
• Honest checkout. IONOS and Kinsta both warn about the same traps: non-transparent pricing, preselected add-ons in the cart, and upsells that inflate a $10 domain into a $40 order. Review the cart line by line before you pay.
• Real support. You will rarely need it — most people contact their registrar once or twice a year — but when you do, it is usually urgent, because a domain problem can take a whole website offline. Look for 24/7 chat or phone support and a real knowledge base.

One thing that does not matter: how long you register for. Registering a domain for ten years instead of one does not help your search ranking — that is a myth, as Kinsta notes. Register for one year unless a multi-year discount is genuinely cheaper, and spend the saving on the renewal instead.

How to find your domain registrar

If you already own a domain and cannot remember where you registered it, there are three ways to find out, in order of speed:

1. Check your billing records. Your registrar is usually the company you paid. Search your email for the registration or renewal invoice — the registrar's name is on it.
2. Use ICANN Lookup. Go to lookup.icann.org, type your domain name, and click Lookup. Scroll to the Registrar Information section — the company listed there is your registrar. This is the method Google Workspace Help recommends.
3. Check for a reseller. If the registrar field is blank, or you cannot sign in with the listed company, scroll down in the same ICANN Lookup result to the Raw Registry RDAP Response and look for the Reseller entry. That is the company you actually bought from — go to its website to manage the domain.

cPanel's documentation adds a second route: InterNIC's whois search lists the registrar's homepage in the Registrar URL line, which is useful when you need the registrar's actual website rather than just its name.

How long can you register a domain name?

The minimum registration is one year, and the maximum is ten years. You can renew for up to ten years at a time, and some registrars advertise longer periods — up to 100 years — but those offers work by the registrar renewing the name for you every ten years, because ICANN's ten-year cap is absolute. If that registrar goes out of business, the longer promise does not survive it.

If a registration lapses, the name does not instantly become available. It passes through a series of grace and redemption phases that usually last months, during which getting it back is difficult and expensive. The exact timing varies by extension, which is why every guide in this area says the same thing: turn on auto-renewal, keep your payment details current, and never let a domain you care about reach its expiry date.

What happens if your registrar goes out of business?

Your domain is not lost. If a registrar is de-accredited or goes out of business, ICANN transfers its domains to another accredited registrar, and the registration continues under the new company. This is one of the reasons accreditation matters: an accredited registrar's customers are protected by ICANN's transfer process, while a reseller with no accredited partner behind it offers no such safety net.

Can you change your domain registrar?

Yes — and it is a normal, routine process. Changing registrars is called a transfer: you unlock the domain at your current registrar, get the authorization code, and give it to the new registrar, which completes the move. The process usually takes about five days, and your website and email keep working throughout, because the nameservers do not change unless you change them. Our guide to how to transfer a domain name to a new registrar walks through every step, including the one timing trap to avoid: never start a transfer in the final days before expiry, because a transfer can take up to 14 days in the worst case and the name could expire mid-move.

One more detail from the rules: after a transfer, the domain cannot be transferred again for a set lock period. ICANN's long-standing 60-day lock was replaced at the ICANN 82 meeting in March 2025 with a 30-day lock for new registrations or transfers, effective within 18 months of that decision, according to Wikipedia.

Frequently asked questions

What is the difference between a domain registrar and a registry?

A registry runs the database for one domain extension — Verisign runs .com — and sets its rules. A registrar is an ICANN-accredited company that sells registrations in that extension to the public. You deal with the registrar; you never deal with the registry directly.

Is a domain registrar the same as web hosting?

No. A registrar reserves your domain name; a web host stores your website's files and serves them to visitors. They are separate services and do not have to come from the same company — in fact, keeping them separate often makes switching hosts easier.

Do I own my domain name or lease it?

You lease it. The registry owns the extension, and your registration gives you the exclusive right to use one name inside it for as long as you keep renewing — up to ten years at a time. If you stop renewing, the name eventually returns to the open market.

How do I find out who my domain registrar is?

Check your email for the registration or renewal invoice, or use ICANN Lookup at lookup.icann.org: enter your domain, click Lookup, and read the Registrar Information section. If the registrar listed is a company you do not recognize, check the raw RDAP response on the same page for a Reseller entry — that is the company you bought from.

Can I change my domain registrar?

Yes. Unlock the domain at your current registrar, get the authorization code, and give it to the new registrar. The transfer usually takes about five days, and your website and email keep working throughout. Do not start a transfer in the final days before expiry, and expect a 30-day lock before you can transfer again.
