We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for Rockland. Source GeoNames US postal codes (2026-07 postal dump) and Census 2024 county Gazetteer (2024 Gazetteer). Updated . ZIP codes are delivery-route groupings, not areas; the boundaries implied by any ZIP map are approximations.

How these codes cluster

Every Rockland ZIP code begins 048. Those first three digits identify the sectional center facility that processes mail for this part of Maine. Statewide that range covers 20 ZIP codes, so Rockland accounts for 5% of it.
