New Orleans Louisiana ZIP Codes

New Orleans holds 61 ZIP codes, spread across 2 parishes.

We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for New Orleans. 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 New Orleans ZIP code begins 701. Those first three digits identify the sectional center facility that processes mail for this part of Louisiana. No other Louisiana community draws on the 701xx range — it belongs entirely to New Orleans.
