Dots summarize approximate ZIP locations grouped by state and three-digit prefix; they are not official delivery boundaries. Colors follow the first digit. Not every number in a displayed range is assigned. Alaska and island insets are relocated and use different scales.
Locations use available coordinates, not delivery boundaries. The simplified world outline may omit small islands; postal associations do not imply administrative ownership.
County outlines are simplified 2017 Census reference geography, not current legal or ZIP delivery boundaries. Highlighting follows postal associations.
