Anyone who has ever created a project from scratch or needed to build a website for their business knows that choosing a domain name is important.
However, it’s common for more interesting and popular names to already be registered to other people.
Check out our article and discover how to verify the availability of a domain and the public information of already registered domains that have sparked your interest.
How to check the availability of a national domain name
Find out how to check the availability of a national domain ending in .com.br:
- Go to the Registro.br website.
- Enter the domain name you want to check.
- Check the result.

If the domain is available, the website itself will offer plans to acquire the name in question.
If the searched domain is unavailable for the .com.br version, Registro.br will suggest some alternative extensions for your website.
How to check the availability of an international domain name
If you are looking for a general domain ending in .com or other extensions, use Namechk instead of the previous option.
- Go to the Namechk website.
- Enter the domain name you want to check.
- See the results for the available extensions for that name.

How do I find out who owns a domain name?
Since domain registration information is public, another way to check domain availability is to find out who registered the name you want to use.
With this information, you can contact the current owner to find out if they are interested in selling the domain name in question.
To do this, simply use one of the free tools available on the internet that track domain information. The main ones are:
- Registro.br: for those who wish to check national domains (ending in .br).
- Whois.com: for those who wish to check international domains.
Registro.br
Simply access the Whois tool on the Registro.br website to check a domain’s information.
After accessing the tool, simply enter the national domain you wish to search and receive information about the company or person who registered that name.

Whois.com#
The process for verifying the owner of international domains is very similar; only the website changes.
Go to Whois.com, search for the domain you want to verify, and check the information about the person or organization that registered that name.

What to do after checking domain availability?
If the domain you wish to purchase is not available, try contacting the current owner to see if they are interested in selling the rights to that name.
If you find this process a bit more complicated because the owner is from another country, seek help from platforms specializing in this service.
There are tools that help in this process and monitor addresses, notifying interested parties about the expiration date of the license.
What are the other alternatives for registering a domain that is already in use?
If the owner of the name in question is not interested in selling or asks for a price outside your budget, the solution is to create a variation of the original name.
Add a keyword to your domain name or choose a different extension, such as .net or .online.
