Check your domain registrar by looking at your WHOIS record
The fastest way to find your domain registrar is to run a WHOIS lookup. WHOIS is a public database that shows who registered a domain name, when it expires, and which company holds the registration. You can search for free at whois.icann.org — the Internet Corporation for Assigned Names and Numbers, which oversees all domain registrations worldwide.
Type your domain name into the search box (for example, "example.com") and the results will show the registrar name in the "Registrar" field. This is the company that sold you the domain and where you pay renewal fees. The WHOIS record also displays your domain's expiration date, which is useful if you need to renew soon.
If you registered your domain years ago and do not remember the company, WHOIS is often the only way to find out. The registrar name appears in the same place regardless of when you registered.
Key Takeaways
- WHOIS lookup at whois.icann.org shows your registrar name in seconds without needing to log in anywhere.
- Your registrar is the company you pay for domain renewal, and it is listed in the "Registrar" field of the WHOIS result.
- If you registered through a web host or website builder, that company may be the registrar or may have registered it on your behalf.
- Check your email for old receipts or confirmation messages from the company that registered the domain — these usually name the registrar.
- If WHOIS shows a privacy service as the registrar contact, contact that service to find out who the actual registrar is.
Look for confirmation emails from when you registered
When you first registered your domain, you received a confirmation email from the registrar. Search your email inbox for messages containing your domain name, the word "registered," or "domain confirmation." These emails usually arrive within minutes of purchase and include the registrar's name, your account number, and login instructions.
Check your spam and trash folders if you cannot find the email in your inbox — domain registration confirmations sometimes get filtered. If you registered the domain more than five or ten years ago, you may need to search your email archive or an old email account you no longer use regularly.
The confirmation email is often easier to find than logging into an account you have not used in years, especially if you have forgotten your password.
Check your web host or website builder account
If you built your website through a platform like Wix, Squarespace, WordPress.com, or GoDaddy, your domain registration may be tied to that account. Log into your website builder and look for a section labeled "Domains," "Domain Settings," or "Domain Management." This section usually shows which registrar holds your domain and displays renewal information.
Some website builders register domains on your behalf and act as the registrar themselves. Others allow you to register through a third-party registrar and simply point your domain to their servers. Either way, your website builder account will show you where the domain is registered and how to renew it.
If you registered your domain through your web host years ago, that host may still be the registrar even if you no longer use them for hosting. You can transfer the domain to a different registrar at any time.
Look at your domain's nameservers to narrow down the registrar
Nameservers are the servers that point your domain to your website. You can see your domain's nameservers by running a WHOIS lookup or by using a DNS checker tool like mxtoolbox.com or whatsmydns.net. The nameserver addresses often contain clues about which company registered your domain.
For example, if your nameservers are "ns1.godaddy.com" and "ns2.godaddy.com," GoDaddy is likely your registrar. If they show "ns1.namecheap.com," Namecheap registered your domain. This method is not foolproof — you can use one registrar and point your nameservers to a different company — but it narrows the possibilities.
Once you have a likely registrar name, you can search your email for messages from that company or try logging into their website with your domain name as the username.
Contact your web host if you are unsure
If you registered your domain through the same company that hosts your website, your web host can tell you immediately. Log into your hosting account and look for a "Domains" or "Domain Management" section, or contact their support team and provide your domain name. They will confirm whether they are the registrar or tell you which company is.
Even if your web host is not the registrar, they usually have records of which registrar you use because they need that information to point your domain to their servers. Support staff can often look this up in seconds.
This is especially helpful if you registered your domain many years ago and have no other way to track it down.
Recover access to your registrar account
Once you know which company registered your domain, you may need to log in to manage it. If you have forgotten your password, most registrars offer a password reset option on their login page. Click "Forgot Password" and follow the steps to reset it using your email address.
If you no longer have access to the email address you used to register, contact the registrar's support team. You will need to verify your identity — usually by providing the domain name, the original registration date, or the last four digits of the credit card used to register. Support can help you regain access or transfer the domain to a new account.
Keep your registrar login information in a safe place once you regain access. You will need it to renew your domain, transfer it to another registrar, or make changes to your nameservers.
Understand what to do if your registrar is out of business
Registrar companies occasionally shut down or get acquired by larger companies. If WHOIS shows a registrar you cannot find online, search the registrar's name plus "acquired" or "shutdown" to see what happened. In most cases, another registrar took over the domains and sent customers notification emails.
If you cannot find information about what happened, contact ICANN directly at icann.org or search the ICANN database for the registrar's current status. You can also try contacting the company that acquired the registrar — they usually inherit all existing domains and customer accounts.
Your domain is not lost if the registrar goes out of business. ICANN requires that another registrar take over the domains, and you can transfer your domain to a registrar of your choice at any time.
Frequently Asked Questions
Can I see who registered my domain if I did not register it myself?
Yes. WHOIS shows the registrant name and contact information for every domain. If someone else registered it for you, their name will appear in the WHOIS record unless they used a privacy service to hide it. If privacy is enabled, you can contact the registrar to request the registrant's information if you have a legitimate reason.
What if WHOIS shows a privacy service instead of a real name?
Many registrars offer WHOIS privacy protection, which hides your personal information and replaces it with the privacy service's contact details. The registrar name is still visible in the WHOIS record. Contact that registrar directly and explain that you need to verify the domain owner — they can help you.
Does my registrar have to be the same company that hosts my website?
No. Your registrar (the company that registered the domain) and your web host (the company that stores your website files) are separate services. You can register with one company and host with another. Your registrar's nameservers simply point to your host's servers.
How do I transfer my domain to a different registrar?
Log into your current registrar's account, find the domain transfer or authorization section, and request an authorization code (also called an EPP code or transfer code). Provide this code to your new registrar and follow their transfer process. The transfer usually takes three to five business days and costs a small fee.
What if I registered my domain through a third-party service like a domain broker?
Domain brokers and resellers register domains through actual registrars on your behalf. WHOIS will show the actual registrar's name, not the broker's. You can contact the registrar directly, or contact the broker and ask them which registrar they used — they should have this information in your account.
