Miami ZIP codes: US ZIP code list for Miami, Florida (FL)

Quick answer

Miami, Florida has 12 US ZIP codes, running 33125 to 33142 inside Miami-Dade County. Each carries the same 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.

Miami ZIP code footprint

How Miami's ZIP footprint compares with national norms.

12 ZIP codes are listed for Miami, covering a population of 455,924. They span 18 numbers, 33125 through 33142. The median covered metro on this site lists 12 codes; Miami 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 331 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Miami passes through one facility. The range runs 33125 to 33142.

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

Frequently asked questions

How many ZIP codes does Miami have?
12. They run from 33125 to 33142 across 1 sectional center prefix (331), spanning 18 numbers.
What is the first ZIP code in Miami, FL?
33125 is the lowest-numbered code serving Miami. Numbering runs roughly northeast to west nationally, so Miami's 331 prefix reflects its position in the Florida sorting network, not its size.
Do all Miami ZIP codes have the same sales tax rate?
