Where there are no carrier routes in an area, ZIP Code boundaries are extended to ensure continuous coverage for the entire United States. In all cases where there are carrier routes, ZIP Codes share a boundary with each.

When there is insufficient data to create ZIP Code polygons in an area, Precisely creates temporary ZIP Code areas with the three-digit ZIP prefix and a two-letter suffix, either MH for an area surrounded by water or MX for an area surrounded by land.
