117th Congressional Districts ZIP Plus 4

Includes Representative Names and Information

This product provides a current listing of 117th Congressional Districts by 9-digit ZIP Code. Sometimes a regular 5-digit ZIP Code spans more than one Congressional District, so using the 9-digit ZIP+4 adds a level of precision not otherwise found. The foundation of this product is true commercial grade ZIP+4 data. From there we utilize multiple sources – including our own plotting when necessary – to obtain a complete and accurate 9-digit ZIP Code to Congressional District relationship. Plus, we add some extras such as congressional representatives by name, primary county, primary city, etc.
