San Francisco California ZIP Codes

San Francisco holds 51 ZIP codes, spread across 2 counties.

We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for San Francisco. 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 San Francisco ZIP code begins 941. Those first three digits identify the sectional center facility that processes mail for this part of California. No other California community draws on the 941xx range — it belongs entirely to San Francisco.
