Buffalo New York ZIP Codes

Buffalo holds 44 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We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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 Buffalo codes above are listed without a column we would have to invent.

Scope every ZIP code recorded for Buffalo. 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 Buffalo ZIP code begins 142. Those first three digits identify the sectional center facility that processes mail for this part of New York. No other New York community draws on the 142xx range — it belongs entirely to Buffalo.
