Hawaii Post Offices
Listing data as of September 18, 2026 · Confirm on USPS.com
Hawaii's 14 post offices are spread across 13 communities on several different islands, so unlike a mainland state, mail here often has to travel by air or inter-island barge before it ever reaches a delivery truck. That adds a day or more to some shipments compared to the mainland, and it's part of why islands other than Oahu tend to have fewer, more centralized post offices. Find your island and city in the list below.
