Southeastern Pennsylvania ZIP Codes

Southeastern holds 3 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We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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 Southeastern codes above are listed without a column we would have to invent.

Scope every ZIP code recorded for Southeastern. 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 Southeastern ZIP code begins 193. Those first three digits identify the sectional center facility that processes mail for this part of Pennsylvania. Statewide that range covers 53 ZIP codes, so Southeastern accounts for 6% of it.

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

• 484 Area code 484
• 610 Area code 610
• 835 Area code 835

These codes are associated with Southeastern through county-level matching, not a per-address guarantee.
