Newburyport Massachusetts ZIP Codes

Newburyport holds a single ZIP code.

We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for Newburyport. 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 Newburyport ZIP code begins 019. Those first three digits identify the sectional center facility that processes mail for this part of Massachusetts. Statewide that range covers 38 ZIP codes, so Newburyport accounts for 3% of it.
