This form lets you find the county, ARRL section, ARRL division, grid square and latitude/longitude of a location (city and state) in the US.

You must enter a city name. If you also enter a state, all cities in that state with the given city name will be listed. If you do not enter a state, all US cities with the given name will be listed.

The database used for this service was created using data from the US Geological Survey (USGS) Geographic Names Information System (GNIS).

Our database contains all of the "populated places" entries from the GNIS database.

ARRL does not guarantee the accuracy of this data.

You can query the entire database at the USGS server if you want to find information (but not ARRL divisions/sections!) about other locations within the US.

Please read this first if you believe there are errors in the lookup data.
