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:
