Omaha Nebraska ZIP Codes

Omaha holds 48 ZIP codes, spread across 2 counties.

We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for Omaha. 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 Omaha ZIP code begins 681. Those first three digits identify the sectional center facility that processes mail for this part of Nebraska. Statewide that range covers 53 ZIP codes, so Omaha accounts for 91% of it.
