Hawaii National Park sits at the heart of Hawaii Volcanoes National Park on the Big Island. This isn't a town. It's a ZIP code serving the national park itself, covering 150 square miles of volcanic landscape from Kilauea's summit to the Pacific Ocean. The post office maintains 235 PO Boxes despite zero residential population in the Census count.
This is a PO Box Only Zone. There's no street delivery alternative anywhere in this 150-square-mile territory. The single addressed location in the ZIP+4 data is Kilauea Military Camp, a military recreation facility operating within park boundaries since 1916. Park rangers, scientists at the Hawaiian Volcano Observatory, concession workers, and military families all rely on PO Boxes here.
The 235 PO Boxes serve far more than just on-site workers. Nearby communities like Volcano (5.8 miles away), Ocean View, Pahoa, and Pahala all sit within driving distance, and some residents prefer to maintain a "Hawaii National Park" mailing address. The post office also handles mail for the park's 1.5 million annual visitors who ship packages or receive forwarded mail.
Four businesses operate within the ZIP, employing 22 people. These include the Volcano House hotel, visitor services, and park operations. The post office doubles as a small community hub where park staff and Volcano Village residents cross paths. Mail arrives via rural route from Hilo, making the long drive along Crater Rim Drive before reaching the post office near the park entrance.
