Quick answer

San Francisco, California has 12 US ZIP codes, running 94102 to 94131 inside San Francisco County. Each carries the same 8.625% combined sales tax rate. ZIP boundaries are postal delivery routes, not tax boundaries — a code that crosses a city or district line can hold more than one rate, so destination-based sellers should validate by full street address.

San Francisco ZIP code footprint

How San Francisco's ZIP footprint compares with national norms.

12 ZIP codes are listed for San Francisco, covering a population of 808,988. They span 30 numbers, 94102 through 94131. The median covered metro on this site lists 12 codes; San Francisco ranks 2 of 94 by count. Large metros carry more codes because USPS splits a delivery area once carrier volume outgrows one route cluster, not because the city is geographically bigger.

All 12 codes share the 941 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to San Francisco passes through one facility. The range runs 94102 to 94131.

ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; California redraws tax and municipal lines on a different schedule entirely. A San Francisco mailing address does not prove an address sits inside San Francisco city limits, and a single code can straddle the boundary.

Why ZIP-based rate lookup is unreliable

USPS redraws ZIP codes when carrier routes change. Tax jurisdictions move with annexations, county lines and voter-approved districts. The two never line up. In California, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the California Department of Tax and Fee Administration lookup at the time of sale.
