Buy your .US.ORG domain

Not in the technical sense — .us.org is not a top-level domain. There is no such entry in the IANA root zone database; us.org is itself an ordinary domain registered in the .org zone, which CentralNic operates as a namespace. Registering example.us.org gives you a third-level name. It works normally in a browser and in email.

The namespace is positioned towards the United States, but that is the operator's commercial choice rather than a regulatory requirement. It is worth repeating that this is not a country extension: us.org is a privately operated name under .org. For current registration terms the operator's own policies apply, and those terms can change over time.

The difference is structural. .org is a genuine extension recorded in the IANA root zone database, operated by the not-for-profit Public Interest Registry within the ICANN contractual framework. .us.org is a privately operated namespace under .org; it has no entry of its own in the root zone and its rules follow the operator's policies.

The rules follow the organisation operating the us.org namespace: CentralNic, today part of Team Internet Group. Registration rules, renewal terms and dispute procedures answer to that organisation's own policies. The ICANN contractual framework standing behind a genuine top-level domain does not apply here in the same way, and the distinction is worth knowing before you register.

If you are building a not-for-profit identity, .org in the root zone is the first option to look at; Public Interest Registry describes it as open and unrestricted. If you address a global audience, .com is more familiar. .us.org usually comes up once those names are taken; check the alternatives with a bulk domain name search.
