Monroe Louisiana ZIP Codes

Monroe holds 10 ZIP codes, all inside one parish and one postal prefix.

We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for Monroe. 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 Monroe ZIP code begins 712. Those first three digits identify the sectional center facility that processes mail for this part of Louisiana. Statewide that range covers 63 ZIP codes, so Monroe accounts for 16% of it.
