.us

.us is the country-code top-level domain for the United States. Unlike globally open country-code extensions such as .me or .io, .us has a formal Nexus requirement that determines who is eligible to register and keep a domain.

Eligible registrants include U.S. citizens and permanent residents, people whose primary domicile is in the United States or its possessions, qualifying U.S.-based organizations and government entities, and certain foreign organizations with a bona fide presence in the United States. The registry can conduct Nexus checks and may require supporting evidence when a registration is reviewed.

For eligible users, .us can provide a direct geographic signal for American businesses, local services, civic projects, communities and organizations that want the country association to be visible in the web address. That signal can be useful when the U.S. market is central to the identity rather than simply one market among many.

The Nexus requirement is not a one-time marketing label; the registrant must actually qualify under the policy. Before registering .us, confirm the appropriate Nexus category with the registrar and make sure the registration information remains accurate. Trademark and other legal rules apply separately.
