USA.gov is an official website of the United States government. It is an interagency product administered by USAGov (formerly the Federal Citizen Information Center), a division of the U.S. General Services Administration's Technology Transformation Service.

The site houses information published by the U.S. government, including information about U.S. government programs, and services. The site's search function only returns results from government web pages, most ending in .gov or .mil.

The site also contains the A to Z Index of U.S. Government Departments and Agencies, which contains contact information and web addresses of hundreds of federal agencies, sub-agencies, and divisions, as well as state government contact information.
