How Hawaii ZIP codes are numbered

967xx–968xx

The first three digits identify the sectional center facility that processes mail for a region, so a Hawaii ZIP code can be placed geographically from its prefix alone. Each row names the city holding the most codes in that prefix.

Hawaii three-digit ZIP prefixes, the codes in each, and the city that holds the most of them.
Prefix	ZIP codes	Main area
967xx	87	Hilo
