Abstract | zip displays ZIP Code areas. The USPS does not recognize zip polygons. Zip codes with the USPS are arranged by mail carrier route and are linear. Zip code polygons are drawn using the collective zip codes in adparcel with the boundary following parcels from paregion. Currently (6/2022) we are not including addresses that are unique (high volume of mail to 1 address, such as PCC) or post office boxes. To verify addresses please use the USPS website "Look Up a ZIP Code" at https://tools.usps.com/zip-code-lookup.htm See more information. | |
Known errors/qualifications | Metropolitan boundaries are delineated well. Rural boundaries are extrapolated in some areas. Refer to US Postal Service for latest ZIP Code routes and for exact individual addresses. Zip codes defined by the US Postal Service as "unique", "military", and "post office box" are not included in this layer as they have no defined are 10/2013: While this layer is maintained as a feature class in gdbmaint, the coverage format is still required for certain nightly processing.
