ZIP codes by population type
This page lists the five population-type classifications used across ZipLocal Guide, with the number of ZIP codes and states in each. The type shown for a ZIP is the classification already printed on that ZIP's own profile page. The ZIP and state counts come from the site's ZIP records (GeoNames postal data joined to U.S. Census ACS 2022 estimates).
