cbsa codes This product provides a current listing of 115th Congressional Districts by 9-digit ZIP Code. Sometimes a ZIP Code spans more than one Congressional District, so using the 9-digit ZIP+4 is a better option than our 5-digit ZIP Code Congressional Districts product. 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.
