Milwaukee ZIP codes: US ZIP code list for Milwaukee, Wisconsin (WI)

Quick answer

Milwaukee, Wisconsin has 12 US ZIP codes, running 53202 to 53218 inside Milwaukee County. Each carries the same 7.9% 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.

Milwaukee ZIP code footprint

How Milwaukee's ZIP footprint compares with national norms.

12 ZIP codes are listed for Milwaukee, covering a population of 561,385. They span 17 numbers, 53202 through 53218. The median covered metro on this site lists 12 codes; Milwaukee 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 532 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Milwaukee passes through one facility. The range runs 53202 to 53218.

ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Wisconsin redraws tax and municipal lines on a different schedule entirely. A Milwaukee mailing address does not prove an address sits inside Milwaukee 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 Wisconsin, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the Wisconsin Department of Revenue lookup at the time of sale.

What is the first ZIP code in Milwaukee, WI?
