Quick answer
Juneau, Alaska has 5 US ZIP codes, running 99801 to 99824 inside Juneau City and Borough. Each carries the same 5% 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.

Juneau ZIP code footprint
How Juneau's ZIP footprint compares with national norms.
5 ZIP codes are listed for Juneau, covering a population of 31,685. They span 24 numbers, 99801 through 99824. The median covered metro on this site lists 12 codes; Juneau ranks 88 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 5 codes share the 998 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Juneau passes through one facility. The range runs 99801 to 99824.
ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Alaska redraws tax and municipal lines on a different schedule entirely. A Juneau mailing address does not prove an address sits inside Juneau 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 Alaska, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the Alaska Department of Commerce (Alaska Municipal League rate tables) lookup at the time of sale.
