New Alexandria Pennsylvania ZIP Codes

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We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for New Alexandria. 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 Alexandria ZIP code begins 156. Those first three digits identify the sectional center facility that processes mail for this part of Pennsylvania. Statewide that range covers 77 ZIP codes, so New Alexandria accounts for 1% of it.
