About .us

.us is the country code top-level domain for the United States. It is managed by Registry Services, LLC, based in Tempe, Arizona.

There are no strict eligibility restrictions for most registrants, though some subdomains like .state.us or .county.us are reserved for government entities. The .us domain was one of the first TLDs ever created, registered on February 15, 1985. It has been operated by several entities over the years, with Registry Services taking over in recent times. The domain is widely used for local and regional websites, often by schools, libraries, and municipal governments.
