The USPS now officially publishes ZIP Code boundary polygons through its Postal Pro platform, making geospatial data freely available for developers and researchers. This long-awaited public release provides precise geographic outlines for all ZIP Code Tabular Areas (ZCTAs) in the United States.
Background
ZIP Code boundary data has historically been difficult to obtain in official vector polygon format, with many developers relying on third-party or approximate datasets. The USPS released ZCTA (ZIP Code Tabular Area) shapes as part of their TIGER/Line data partnership with the Census Bureau, but this marks a more direct and accessible offering.
