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

Quick answer

Aurora, Colorado has 9 US ZIP codes, running 80010 to 80018 inside Arapahoe County. Each carries the same 8% 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.

Aurora ZIP code footprint

How Aurora's ZIP footprint compares with national norms.

9 ZIP codes are listed for Aurora, covering a population of 395,052. They span 9 numbers, 80010 through 80018. The median covered metro on this site lists 12 codes; Aurora ranks 69 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 9 codes share the 800 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Aurora passes through one facility. The range runs 80010 to 80018.

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

Frequently asked questions

Common questions about this area.

How many ZIP codes does Aurora have?
9. They run from 80010 to 80018 across 1 sectional center prefix (800), spanning 9 numbers.
What is the first ZIP code in Aurora, CO?
80010 is the lowest-numbered code serving Aurora. Numbering runs roughly northeast to west nationally, so Aurora's 800 prefix reflects its position in the Colorado sorting network, not its size.
Do all Aurora ZIP codes have the same sales tax rate?
