Congressional District Data | 112th Congress

There are many applications where it would be helpful to determine what Congressional District a ZIP Code falls within, along with who is the Congressional Representative for that district.

We have a great product that is kept current which indicates the Congressional Districts that a ZIP Code covers, along with an estimated percentage. For instance, a ZIP Code may be 80% in one Congressional District and 20% in another Congressional District.

Note: We go way beyond just extracting data from USPS files. There are many missing and innaccurate records that we have manually entered to make this a current, complete and accurate product.

We also have a new ZIP+4 Congressional District product. This has a range of records based on ZIP+4 matching to a congressional district. For instance:

• ZIP 12345-0001 - 12345-5999 is in District 1
• ZIP 12345-6000 - 12345-9999 is in District 2

Call for details on the ZIP+4 Congressional District product.
