Cicero - Zip to District

Match zip codes to national, state, or local legislative districts with our zip code lookup files. Choose from a variety of options and match types.

Though less accurate than full address matching, zip codes are still a popular way to match areas to legislative districts. We provide 5 or 9 digit zip to district files that can be customized to your needs at any level of government. We can also improve the match rate with our population based zip to district matching.
