USPS releases official ZIP Code boundary polygons
Original: USPS now offers official ZIP Code boundary polygons
The United States Postal Service has begun publishing official ZIP Code boundary polygon files through its PostalPro platform, making authoritative geographic definitions of ZIP Code areas directly available for the first time. Developers, mapping specialists and data analysts have long relied on third-party estimates of these boundaries, so the move is drawing attention from the geospatial community, with many noting it could improve the accuracy of location-based analysis.
Why now: ZIP Code boundaries were previously only available as unofficial approximations, so free official data is a notable change for mapping and data work.
