What Exactly is .US?

We are the country code top-level domain (ccTLD) for the United States. You might have thought .us is only for government agencies and schools. But since 2002, individuals, businesses, churches, and non-profits have adopted .us web addresses to make their mark on the internet. Neustar, a leading provider of registry services, manages .us on behalf of the U.S. Department of Commerce. Neustar maintains a growing network of .us-accredited registrars that sell .us domain names. See a full list of .us registrars.
