Phoenix ZIP codes: US ZIP code list for Phoenix, Arizona (AZ)

Quick answer

Phoenix, Arizona has 12 US ZIP codes, running 85003 to 85051 inside Maricopa County. Each carries the same 8.6% 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.

Phoenix ZIP code footprint

How Phoenix's ZIP footprint compares with national norms.

12 ZIP codes are listed for Phoenix, covering a population of 1,650,070. They span 49 numbers, 85003 through 85051. The median covered metro on this site lists 12 codes; Phoenix 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 850 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Phoenix passes through one facility. The range runs 85003 to 85051.

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 Phoenix mailing address does not prove an address sits inside Phoenix 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.

Frequently asked questions

Common questions about this area.

How many ZIP codes does Phoenix have?
12. They run from 85003 to 85051 across 1 sectional center prefix (850), spanning 49 numbers.
What is the first ZIP code in Phoenix, AZ?
85003 is the lowest-numbered code serving Phoenix. Numbering runs roughly northeast to west nationally, so Phoenix's 850 prefix reflects its position in the Arizona sorting network, not its size.
Do all Phoenix ZIP codes have the same sales tax rate?
Inside Phoenix city limits, yes — 8.6% applies. A code that extends past the city line can carry a different rate on part of its territory. Validate by street address, not ZIP, when the sale is destination-based. Confirm current rates with your state revenue agency before filing.
