Cheyenne ZIP codes: US ZIP code list for Cheyenne, Wyoming (WY)

Quick answer

Cheyenne, Wyoming has 3 US ZIP codes, running 82001 to 82009 inside Laramie County. Each carries the same 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.

Cheyenne ZIP code footprint

How Cheyenne's ZIP footprint compares with national norms.

3 ZIP codes are listed for Cheyenne, covering a population of 65,132. They span 9 numbers, 82001 through 82009. The median covered metro on this site lists 12 codes; Cheyenne ranks 93 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 3 codes share the 820 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Cheyenne passes through one facility. The range runs 82001 to 82009.

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

How many ZIP codes does Cheyenne have?
3. They run from 82001 to 82009 across 1 sectional center prefix (820), spanning 9 numbers.
What is the first ZIP code in Cheyenne, WY?
82001 is the lowest-numbered code serving Cheyenne. Numbering runs roughly northeast to west nationally, so Cheyenne's 820 prefix reflects its position in the Wyoming sorting network, not its size.
Do all Cheyenne ZIP codes have the same sales tax rate?
