Honolulu ZIP codes: US ZIP code list for Honolulu, Hawaii (HI)

Quick answer

Honolulu, Hawaii has 9 US ZIP codes, running 96813 to 96826 inside Honolulu County. Each carries the same 4.5% 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.

Honolulu ZIP code footprint

How Honolulu's ZIP footprint compares with national norms.

9 ZIP codes are listed for Honolulu, covering a population of 350,964. They span 14 numbers, 96813 through 96826. The median covered metro on this site lists 12 codes; Honolulu 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 968 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Honolulu passes through one facility. The range runs 96813 to 96826.

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

What is the first ZIP code in Honolulu, HI?
