How to Check Where a Domain Is Registered

If you need to verify which registrar manages a domain, you can use a WHOIS lookup service. WHOIS databases contain registration information about domain names, including details such as the registrar, registration dates, nameservers, and domain status.

This can be useful when:

• Managing domains for clients.
• Preparing a domain transfer.
• Verifying domain ownership information.
• Identifying the current registrar.
• Troubleshooting DNS or delegation issues.

Using a WHOIS Lookup Service

One of the easiest ways to check domain registration information is by using:

WHO.IS Domain Lookup

Check a Domain

1. Open:

https://who.is

2. Enter the domain name you want to verify.

Example:

yourdomain.com

3. Click the search button.

After a few moments, the service will display information obtained from the appropriate domain registry.

Finding the Registrar

Within the WHOIS results, locate the section labeled:

Registrar

or

REGISTRAR

This field indicates the company through which the domain was registered.

Example

REGISTRAR:
Example Registrar Ltd.
123 Example Street
City, Country

The company listed in this field is the current domain registrar.

Information Available in WHOIS

Depending on the domain extension and privacy settings, WHOIS records may contain:

• Registrar name
• Registration date
• Expiration date
• Nameservers
• Domain status
• DNSSEC status
• Technical contacts
• Administrative contacts

Some personal information may be hidden due to privacy regulations such as GDPR.

Official WHOIS Services

For the most accurate information, you can also use WHOIS services provided directly by the registry responsible for a specific domain extension.
