This product provides a listing of Congressional Districts by 9-digit ZIP Code for the current 119th Congress. It also provides contact information, party affiliation, and committee assignments for each representative. The same is included for senators along with their election cycle.
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, and more.
