Augusta Maine ZIP Codes

Augusta holds 5 ZIP codes, all inside one county 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We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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 Augusta codes above are listed without a column we would have to invent.

Scope every ZIP code recorded for Augusta. 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 Augusta ZIP code begins 043. Those first three digits identify the sectional center facility that processes mail for this part of Maine. Statewide that range covers 26 ZIP codes, so Augusta accounts for 19% of it.

ZIP codes and area codes are separate systems — one routes mail, the other routes calls — and they do not share boundaries. The code below serves the same ground Augusta occupies.
