Need to add Congressional districts or Senator and Representative contact information to latitude/longitude coordinates in bulk? You're in the right place.

This article shows you how to add Congressional districts to latitude/longitude coordinates using Geocodio. The Congressional district data returned includes approximate addresses, Congressional district number, Congress number, and Congress years, with the option to append legislator data. You can use our API to integrate it into a website, or upload Excel, CSV, and TSV files.

New: 120th Congress (cd120) Preview Available - Congressional district boundaries for the 120th Congress are now available as a preview via the field append. The data is accurate, though some states may receive updates as final redistricting changes are published. The default field append continues to use the 119th Congress (cd119).

With Geocodio, you can choose to just get the raw data back (via spreadsheet or API), or view the locations on a map with Congressional district outlines.
