Thanks to an asinine rule by Registry Services, LLC, all .us domains are required to use your actual contact information for your whois information.
Proxy, or privatized registrations, are not permitted under current policy. The usTLD has an ongoing interest in ensuring that its top-level domain is administered in a secure manner and that the information contained within the authoritative database is reliable, accurate, and up-to date. One of the mechanisms to ensure the integrity of the .US namespace is the through the collection of true registrant information. The usTLD Registry employs an algorithm to detect the inadvertent or intentional registration of proxy, anonymous and/or private domain name registrations, and enforces a registrar’s obligation to not offer such services to .US domain name registrants.
