Lists and Geographic Codes
Shapefiles for Mapping
USPS ZIP Code Crosswalk Files (HUD): These crosswalk files, which link ZIP Codes to multiple different geographies—from census tracts to congressional districts—are updated quarterly.
ZIP Code Tabulation Area to County Bridge (StatsAmerica): ZIP Code Tabulation Areas (ZCTAs) were assigned to both Census and BEA counties based on population-weighted ZCTA centroids. This bridge is based on TIGER 2018 shapefiles from the U.S. Census Bureau, and the centroids were weighted based on Census 2010 block-level population.
Geocorr Geographic Correspondence Engine (Missouri Census Data Center): Generate your own crosswalk files for dozens of geographic layers, complete with the ability to weight by population, land area or housing units.
