About the usTLD
For anyone with a dream to chase, an idea to share, a cause to champion, or a business to promote, .US gives you a memorable and credible way to reach your audience online.
American workers and businesses operate in a rapidly changing and increasingly competitive world. To address these challenges, we have developed bold new strategies to accelerate and promote U.S. economic growth and opportunity.
Registry Services, LLC, manages the usTLD on behalf of the U.S. Department of Commerce. The Registry Services team and supporting infrastructure have successfully managed the usTLD space since 2001. The structure of the usTLD namespace is like no other domain name space – there is both a traditional second-level registration space and a deeply hierarchical locality-based namespace. Registry Services places great emphasis on the promotion and increased awareness of the usTLD in the second-level space while nurturing the locality-based namespace and maintaining our commitment to ensuring the highest of service levels. The usTLD is poised for further growth and innovation in the public interest, and Registry Services will continue to provide exceptional services to the DOC, Registrars, Delegated Managers and the American Internet Community.

Second-Level Domain Name Space
A second level domain refers to the name to the left of the dot "." of a .US domain extension. The expanded second level domain name space was launched in April 2002 and has since increased usTLD second-level registrations from zero to over 1.7 million domain names.
Locality Domain Namespace
Registrations in the locality space have been in existence since 1992 and reflect the oldest part of the usTLD domain namespace. These registrations represent the political geography of the United States based on two-letter state abbreviations and divided further into localities, including cities, counties, parishes, townships, or local names (e .g., Alexandria.va.us). In addition to geographical locality names, the usTLD locality space also includes certain affinity names, for example, STATE, FED, K12, LIB, and NSN (Native Sovereign Nation). Locality and affinity names collectively compose the "locality space."
The State of usTLD Policies and Procedures
As the usTLD Administrator, Registry Services takes seriously its responsibility to act as the trustee for the .US domain, serving both the local and global Internet communities. We have devloped usTLD policies and processes to ensure the integrity of the usTLD, and to provide a model for management of country-code domain names and future new geographic city-based generic top level domains around the world.
The usTLD has evolved into an acknowledged model of TLD management, delivering a safe, reliable, and policy-rich name space operating in the public interest. A key component of our successful management has been the development, implementation and enforcement of unique usTLD policies and procedures that support the steady, responsible growth of registrations in the second-level expanded space while also ensuring compliance with all required policies and registration procedures.
- The usTLD Nexus requirements that ensure that registrants are reliably subject to United States law and the jurisdiction of United States courts;
- A requirement for accurate, reliable and up-to-date WHOIS data backed up by tools and procedures to proactively identify and address inaccurate and/or incomplete data;
- True registrant accountability ensured by a prohibition on private/proxy registrations;
