Quick answer
Tucson, Arizona has 10 US ZIP codes, running 85701 to 85746 inside Pima County. Each carries the same 8.7% 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.

Tucson ZIP code footprint
How Tucson's ZIP footprint compares with national norms.
10 ZIP codes are listed for Tucson, covering a population of 543,242. They span 46 numbers, 85701 through 85746. The median covered metro on this site lists 12 codes; Tucson ranks 55 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 10 codes share the 857 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Tucson passes through one facility. The range runs 85701 to 85746.
ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Arizona redraws tax and municipal lines on a different schedule entirely. A Tucson mailing address does not prove an address sits inside Tucson 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 Arizona, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the Arizona Department of Revenue lookup at the time of sale.
