We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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 Superior codes above are listed without a column we would have to invent.

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

How these codes cluster

Every Superior ZIP code begins 513. Those first three digits identify the sectional center facility that processes mail for this part of Iowa. Statewide that range covers 23 ZIP codes, so Superior accounts for 4% of it.
