USA.gov is the official web portal of the United States federal government. It is designed to improve the public’s interaction with the U.S. government by quickly directing website visitors to the services or information they are seeking, and by inviting the public to share ideas to improve government. USA.gov links to every federal agency and to state, local, and tribal governments, and is the most comprehensive site in—and about—the U.S. government. While the primary target audience of USA.gov is the American public, about 25 percent of USA.gov’s visitors come from outside the United States.
USA.gov is part of the Office of Citizen Services and Innovative Technologies in the General Services Administration (GSA), and includes the Spanish-language web portal to U.S. government services, GobiernoUSA.gov (formerly espanol.gov). The portals, which are funded by U.S. taxpayers and are offered as a public service, are a member of the Office of Citizen Services and Innovative Technologies' family of websites that also includes Publications.USA.gov, Kids.gov, and HowTo.gov (formerly WebContent.gov).
