WHOIS Domain Lookup

Find out who owns any domain name

Enter the domain without "www" (e.g. registros.com)

How can I find out who owns a domain name?

WHOIS is the standard protocol for querying who registered an internet domain name. It is a public database that domain registrars are required to maintain, recording information such as the owner's name, the registrar used, registration and expiry dates, and the associated name servers.

To find out who owns a domain, simply enter it in the WHOIS search tool at the top of this page. Within seconds you will see all publicly available information: registrant name, organization, country, contact email, registrar and key dates.

Note that, since the General Data Protection Regulation (GDPR) came into force in Europe, many personal details are hidden or "redacted" in WHOIS records. In those cases, the lookup will show the privacy service provider's details instead of the actual domain owner's information.

How can I view domain owner data?

The fastest way is to use the WHOIS tool on this page. You can also query other WHOIS services directly:

If the domain you want to look up is a country-code domain (ccTLD), the official registry for each country has its own WHOIS service. Here are the main registries for Latin America:

In the WHOIS result, look for the Registrant field. This is where the domain owner's name, organization and contact details appear. When a privacy service is active, this field will show the privacy provider's details instead of the actual owner's.

How can I contact a domain owner?

If the domain you are interested in is already registered and you wish to contact its owner — for example, to propose a purchase or report an issue — you can do so using the contact information in the WHOIS record. Many registrars offer a masked contact form: instead of showing the owner's real email, WHOIS includes a proxy address that forwards your message to the owner without revealing their personal data. Send a clear, concise message explaining who you are and why you are reaching out; owners tend to respond when the proposal is genuine.

Frequently asked questions about WHOIS data privacy.

Why aren't the domain owner's details shown?

There are several reasons why WHOIS may not display the actual registrant's data:

First, the General Data Protection Regulation (GDPR) of the European Union required registrars to hide personally identifiable data for their European registrants from May 2018. This affects generic domains such as .com, .net and .org managed by European registrars in particular.

Second, ICANN (the organization that regulates domains globally) established a temporary model for WHOIS data access in 2018 that allows registrars to hide individuals' data even outside Europe, in compliance with various local privacy laws.

Third, the domain owner may have voluntarily purchased a WHOIS privacy service (also called "Domain Privacy" or "WHOIS Privacy"). This service replaces the registrant's data with that of the privacy agent, hiding the real identity of the registrant.

Finally, some country-code domain registries (ccTLDs) have their own policies that restrict the public information available in their WHOIS, regardless of whether the registrant has activated privacy protection.

What does "redacted for privacy" mean?

The phrase "redacted for privacy" appears in WHOIS when the registrar has removed a personal data field to comply with data protection regulations, primarily the European GDPR. It does not mean the domain is fraudulent or that the owner has anything to hide — it is simply the industry's response to legal privacy requirements.

Can I hide my details in WHOIS?

Yes. Most registrars offer a WHOIS privacy service that replaces your contact details with those of a privacy agent. At Registros.com you can activate this protection when registering the domain or at any time from the client panel.

Note that some country-code domain registries (ccTLDs) do not permit privacy services or restrict them to individuals, so availability may vary depending on the domain extension.

Can I update my WHOIS data?

Yes. You can update your domain's contact details (name, address, phone number, email) from your registrar's client panel at any time. It is important to keep this information accurate, as ICANN requires it to be truthful — in some cases a domain can be cancelled if false information is detected. If your domain is at Registros.com, go to the domains section of the client area to edit the contacts for any of your domains.

How to use WHOIS

Using WHOIS is straightforward: enter the domain name you want to look up in the search bar at the top of this page (without "www") and click "Look up". Within seconds you will get all publicly available information about that domain.

The WHOIS result includes several fields with relevant information. Here is what each one means:

  • Registrant Name The domain holder's name. For individuals this is their full name; for companies, their registered business name.
  • Registrant Organization The name of the organization or company that owns the domain, if applicable.
  • Expiration Date The date the domain registration expires. After this date the domain may become available if the owner does not renew it.
  • Creation Date The date the domain was first registered. The older this date, the more established the domain.
  • Updated Date The date of the most recent change to the domain data (DNS update, contact details change, etc.).
  • Registrar The registrar company where the domain is registered (e.g. Registros.com, GoDaddy, Namecheap, etc.).
  • Nameserver The DNS name servers associated with the domain. They indicate which servers handle traffic for that domain.
What is WHOIS?

WHOIS is a public query protocol created in the 1980s that retrieves information about the registered holder of an internet domain name. The data is stored in databases maintained by domain registries (such as Verisign for .com) and registrars, and is publicly accessible through tools like this one.

How do I use WHOIS to check when a domain expires?

Enter the domain in the WHOIS search on this page and look for the Expiration Date (or "Registry Expiry Date") field in the results. That date shows when the domain registration expires. If the date has already passed, the domain may be in a grace period or may already be available.

How do I find out when a domain becomes available again?

Once a domain expires, the owner has a grace period (typically 30–45 days depending on the registrar) during which they can renew it without losing it. If they do not renew, the domain enters a redemption period (30 additional days) during which it can be recovered at extra cost. After both periods end, the domain is released and anyone can register it.

To track when a domain becomes available, you can use monitoring services such as ExpiredDomains.net or backorder services that attempt to register the domain the moment it becomes available.

WHOIS Questions

Everything you need to know about WHOIS lookups and domain privacy.

Is the WHOIS lookup free?

Yes. WHOIS lookups are completely free and do not require creating an account. You can look up as many domains as you need with no limits.

Why do some domains show no WHOIS information?

Some domains have their data hidden through a privacy service. Other country registries (ccTLDs) have their own privacy policies that limit publicly available information. GDPR regulations in Europe have also restricted the personal information visible in WHOIS lookups.

What should I do if the domain I want is already registered?

If the domain is registered by someone else, you can try contacting the holder using the WHOIS information. You can also use our domain search tool to find available alternatives with other extensions.

Is the domain you want available?

Register it now before someone else takes it. Takes less than 5 minutes.
