Four counties. A different view.

Each card opens a county or county equivalent and its postal associations. Drawn from the complete directory, independently of keyword and state filters.

All cards lead to real records in this snapshot. Illustrations use reference geography, not ZIP delivery boundaries; postal place names are not always municipalities.

02 / PATTERNS ACROSS THE MAP

Where postal names meet.

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.
