Geographic Coverage
Area code 808 is unique in that it covers every county in Hawaii: Honolulu County (Oahu), Hawaii County (the Big Island), Maui County (Maui, Molokai, and Lanai), and Kauai County. Major population centers include Honolulu and Pearl City on Oahu, Hilo and Kailua-Kona on the Big Island, Kahului and Kihei on Maui, and Lihue on Kauai. No other area code serves any part of the state.
Population and Business Context
Hawaii's statewide population of roughly 1.4 million makes the 808 market compact but economically significant. Tourism is the dominant industry, with millions of visitors annually driving demand for hospitality, retail, and transportation businesses. Defense and federal government employment also play a major role, particularly around Pearl Harbor and military installations on Oahu. Agriculture, healthcare, and construction round out the local economy.
Area Code History
Area code 808 was assigned to Hawaii in 1947 as part of the original rollout of the North American Numbering Plan. Because Hawaii was not yet a state at the time (statehood came in 1959), the 808 code was assigned to the territory ahead of its formal admission to the union. The code has never been split and no overlay has been introduced, making 808 one of the few original NANP codes still covering its entire original geographic footprint.
How to Dial
Callers within Hawaii must dial all 10 digits (area code plus 7-digit local number) when placing local calls, following the FCC's nationwide 10-digit dialing mandate. When calling Hawaii from the continental United States or Canada, dial 1 followed by 808 and the 7-digit number. Calls between Hawaiian islands are treated as long-distance calls despite sharing the same area code. No overlay code currently exists for the 808 region.
