zip displays ZIP Code areas.
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 areas.
10/2013: While this layer is maintained as a Shapefile, the coverage format is still required for certain nightly processing. See Steve Whitney.
