This FAQ will explain .US domains

This article will outline .US domains and their restrictions.


.US is the Internet country code top-level domain (ccTLD) for the United States, and can be registered for between 1 and 10 years. 

To register a .US domain name, you must fall within a certain set of requirements. These requirements are commonly referred to as Nexus Requirements. 

The Nexus Requirements state that registrants of .US domain names can be either:

  • an individual who is a citizen of, or lives in, the United States and any of it possessions or territories.
  • An organisation or company based within the United States, or any of its possessions or territories. This includes all non-commercial, federal, state, or local governmental organisations, and their respective subdivisions, as long as they are based within the United States. 
  • A foreign entity or organisation with a bona fide presence within the United States or any of its possessions or territories. This means that a foreign business or entity can register the domain, as long as they maintain an office or similar property within the United States, or regularly engage in lawful activities within the United States. For example, this includes the sales of goods or services within the United States. In cases such as these, the applicant must state their country of citizenship.

Registrants of .US domain names may be contacted by the .US Registry who carry out spot checks on their registrants to ensure that they fall under the Nexus Requirements.
