Quick answer
Philadelphia, Pennsylvania has 12 US ZIP codes, running 19102 to 19146 inside Philadelphia County. Each carries the same 8% 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.

Philadelphia ZIP code footprint
How Philadelphia's ZIP footprint compares with national norms.
12 ZIP codes are listed for Philadelphia, covering a population of 1,550,542. They span 45 numbers, 19102 through 19146. The median covered metro on this site lists 12 codes; Philadelphia 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 191 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Philadelphia passes through one facility. The range runs 19102 to 19146.
ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Pennsylvania redraws tax and municipal lines on a different schedule entirely. A Philadelphia mailing address does not prove an address sits inside Philadelphia 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 Pennsylvania, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the Pennsylvania Department of Revenue lookup at the time of sale.
