The U.S. Gazetteer Files provide a listing of all geographic areas for selected geographic area types. The files include geographic identifier codes, names, area measurements, and representative latitude and longitude coordinates. There are links to the gazetteer files for 116th Congressional Districts, American Indian/Alaska Native/Native Hawaiian Areas, census tracts, counties, county subdivisions, places, school districts, state legislative districts, urban areas, and ZIP Code tabulation areas (ZCTAs) for the 50 states, the District of Columbia, and Puerto Rico. The files go back to 1990.
