In this article, we will explain the policies regarding the United States of America (USA) country-code TLD (.us).

The .us domain name is only available to United States citizens.

Registrants of domains with this extension must be a citizen, resident, organization, or foreign entity that’s somehow affiliated with the United States. The .us domain name is available for private individuals to use, although it is mostly used by local and state governments.

How to Buy a .us Domain

Buying a .us domain extension is easy. First, check the availability of the domain name you want. You will see if the name you want is available, and you will see a few alternatives. Once you’ve decided on a name, you can register the name after choosing the plan that fits your needs.

Who Is Eligible for Registering .us Domains?

The .us domain extension is not available to everyone. Only those included in the following list are allowed to register .us domains:

  • A permanent resident or citizen of the United States or any of its territories
  • An individual whose home or domicile is in the United States or any of its territories
  • An organization or business entity that is incorporated in the US, Washington, DC, or one of its entities 
  • Federal, state, or local US government entities 
  • Political subdivisions that have a genuine presence in the country 




Nexus Category and Nexus requirements

Users seeking a .us ccTLD must indicate which of the three U.S. Nexus categories they belong to and must certify that they have a “bona fide presence in the United States”. These categories are used to physically locate the user. Thus, for each category, various two-digit codes are possible. The first digit of the code (1, 2 or 3) indicates to which category the .us domain belongs.
