Hawaii Zip Codes

139 Zip Codes serve Hawaii

Overview

Hawaii's zip code system follows the standard five-digit format established by the United States Postal Service (USPS). The first digit of Hawaii zip codes generally corresponds to a specific island, with '9' as the initial digit for all of Hawaii. The subsequent digits provide more localized information, distinguishing between regions and neighborhoods within the state. For instance, Oahu primarily uses zip codes starting with '968,' while Maui begins with '967.' Additionally, specific districts and areas within each island are further differentiated by the remaining digits in the zip code. It's worth noting that in some cases, extended zip code formats with additional digits may be assigned to smaller, more specific areas to enhance mail sorting and delivery accuracy.
