ZIP Code boundaries add perspective to your maps, point you toward the good potential customers, and add relevence to your local search.

ZIP Code Boundaries are:

  • Immediate Download. Working on a Saturday and need this data right now? No problem!
  • Sourced from the USPS, then enhanced and improved using proprietary processes.
  • Compiled with strict methodology and algorithms that align ZIP Code data with streets to eliminate overlaps.
  • Comprehensive, providing coverage across the entire United States including Washington DC and Puerto Rico.
  • Complete with latitude/longitude for all ZIP Code polygons, and ZIP Code centroids.
  • Easy to integrate with other datasets including Neighborhood Boundaries, County Boundaries, City Boundaries, and other GIS databases.
  • Our data is updated every quarter, not yearly like other sources.
  • These are not ZCTA boundaries, but current USPS defined ZIP Codes.
  • Continuous Coverage! Unlike others who have gaps in their boundaries for areas not covered by a ZIP Code, we have filler Polygons that ensure full coverage of the United States.
  • Available in multiple major GIS formats:
    • ESRI - Shapefile (.shp)
    • Google Display - KML (.kml)
    • DB Loadable - WKT (.txt)
    • DB Loadable - MySQL™ (.sql)
    • DB Loadable - SQL Server (.sql)
    • DB Loadable - Post GIS (.sql)
    • Comma Separated Values (.csv)
