.us is the Internet country code top-level domain (ccTLD) for the United States. It was established in February 1985. Registrants of .us domains must be U.S. citizens, residents, or organizations – or foreign entities with a presence in the United States or any territory of the United States.[2] Most registrants in the U.S. have registered for .com, .net, .org and other gTLDs, instead of .us, which has primarily been used by state and local governments, even though private entities may also register .us domains.[3] The domain is managed by Registry Services, LLC, a domain name registry, on behalf of the United States Department of Commerce.[4]

The .us domain is less commonly used by American businesses and enterprises than the more international .com.[5]
