Spokane ZIP codes: US ZIP code list for Spokane, Washington (WA)

Quick answer

Spokane, Washington has 10 US ZIP codes, running 99201 to 99223 inside Spokane County. Each carries the same 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.

Spokane ZIP code footprint

How Spokane's ZIP footprint compares with national norms.

10 ZIP codes are listed for Spokane, covering a population of 229,447. They span 23 numbers, 99201 through 99223. The median covered metro on this site lists 12 codes; Spokane ranks 55 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 10 codes share the 992 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Spokane passes through one facility. The range runs 99201 to 99223.

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

Frequently asked questions

How many ZIP codes does Spokane have?
10. They run from 99201 to 99223 across 1 sectional center prefix (992), spanning 23 numbers.
What is the first ZIP code in Spokane, WA?
99201 is the lowest-numbered code serving Spokane. Numbering runs roughly northeast to west nationally, so Spokane's 992 prefix reflects its position in the Washington sorting network, not its size.
Do all Spokane ZIP codes have the same sales tax rate?
