Fontanelle Iowa ZIP Codes

Fontanelle holds a single ZIP code.

We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for Fontanelle. 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.

Every Fontanelle ZIP code begins 508. Those first three digits identify the sectional center facility that processes mail for this part of Iowa. Statewide that range covers 28 ZIP codes, so Fontanelle accounts for 4% of it.
