Address and map lookup

Find the county for an address.

Cities, mailing addresses, and county boundaries do not always line up cleanly. Search the exact address and keep the county result attached to its point on the map.

County Names & Lines address search results on the map
The short answer

Enter a U.S. address in County Names & Lines, select the result, and the app shows its county with map, coordinate, and available FIPS context.

Search the location you actually mean

Use a complete street address when possible. The selected result stays visible on the map, which is especially helpful when a city or ZIP code spans more than one county.

  • U.S. address search
  • Mapped search result
  • County and location details

Check a point without an address

Drop a point on the map to inspect another location. This helps with rural places, route planning, outdoor locations, and field sites where a postal address is not the best reference.

  • Point-on-map lookup
  • Copy and share
  • Coordinate context

Use the result as a location check

The app identifies counties; it does not replace a government jurisdiction determination, property survey, or legal boundary record when formal verification is required.

Keep the county answer in your pocket.

Open the map, see the county, and understand the line around you without digging through a stack of websites.
