We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP. USPS delivery-type products are licensed, and no clean-rights source maps ZIP codes to neighbourhoods — so the Gray codes above are listed without a column we would have to invent.

Scope every ZIP code recorded for Gray. Source GeoNames US postal codes (2026-07 postal dump) and Census 2024 county Gazetteer (2024 Gazetteer). Updated 15 July 2026. ZIP codes are delivery-route groupings, not areas; the boundaries implied by any ZIP map are approximations.

How these codes cluster

Every Gray ZIP code begins 501. Those first three digits identify the sectional center facility that processes mail for this part of Iowa. Statewide that range covers 69 ZIP codes, so Gray accounts for 1% of it.
