Denver ZIP codes: US ZIP code list for Denver, Colorado (CO)

Quick answer

Denver, Colorado has 12 US ZIP codes, running 80202 to 80231 inside Denver County. Each carries the same 8.81% 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.

Denver ZIP code footprint

How Denver's ZIP footprint compares with national norms.

12 ZIP codes are listed for Denver, covering a population of 715,522. They span 30 numbers, 80202 through 80231. The median covered metro on this site lists 12 codes; Denver 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 802 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Denver passes through one facility. The range runs 80202 to 80231.

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

What is the first ZIP code in Denver, CO?
80202 is the lowest-numbered code serving Denver. Numbering runs roughly northeast to west nationally, so Denver's 802 prefix reflects its position in the Colorado sorting network, not its size.
Do all Denver ZIP codes have the same sales tax rate?
