Hawaii is served by a single area code as of 2026. This guide walks through which code it is, when it was assigned, how it has held up against population growth, and what the prospects look like for additional codes in the future.
The Short Answer
Hawaii currently has one active area code in service. The code has held its territory without needing relief since it was assigned, which reflects Hawaii’s population size and the rate at which new phone lines are being activated in the state.
By population, Hawaii ranks #40 nationally with roughly 1,434,952 residents as of the most recent estimates. That puts the state’s area code count in line with its population peers — denser, faster-growing states need more codes; smaller states need fewer.
The Hawaii Area Code
The active area codes serving Hawaii are listed below, in numerical order. Where a code is an overlay or a split-off from an earlier code, that relationship is noted.
- 808 — All of Hawaii (all islands), plus Wake Island in the western Pacific
How Hawaii’s Area Codes Grew Over Time
Hawaii received its first area code after the original 1947 NANP launch. The full sequence of code activations and splits is laid out below.

Browse Hawaii Area Codes →- 1947 — Hawaii was not assigned an area code at the launch of the North American Numbering Plan, as it was not yet a state and was not initially included in the system.
- 1957 — 808 was assigned to the Territory of Hawaii on August 8, 1957, about two years before Hawaii became a state in 1959. It serves all of the Hawaiian Islands and also covers Wake Island.
- 2021 — 808 transitioned to mandatory ten-digit dialing on October 24, 2021, after the central office code 988 was reserved nationwide for the Suicide and Crisis Lifeline, ending the seven-digit dialing that Hawaii's exchanges had used.
What’s Next for Hawaii Area Codes
808 is the only area code serving Hawaii, and it is not under near-term exhaust pressure. Despite the state’s mobile-number growth, particularly on Oahu, NANPA projects that the single 808 numbering plan area will have enough numbers to serve the state until at least the third quarter of 2035. No relief planning (split or overlay) is currently scheduled, so a second Hawaii area code is not expected this decade.
Frequently Asked Questions
How many area codes does Hawaii have?
Hawaii has one area code: 808. It covers the entire state, all islands, and has done so since 1957. It is one of the few U.S. states still served by a single area code.
What is the newest area code in Hawaii?
The most recent area code addition to Hawaii was 808, activated in 2021. New phone lines provisioned in its service area are increasingly drawn from this code as older overlays approach exhaustion.
Does 808 cover all of the Hawaiian Islands?
Yes. 808 serves every island in the state, including Oahu (Honolulu), Maui, Hawaii Island (the Big Island), Kauai, Molokai, and Lanai. It also covers Wake Island, a U.S. territory in the western Pacific.
Why do I have to dial all 10 digits for a local call in Hawaii?
Since October 24, 2021, all calls within 808 require ten-digit dialing. The change was made because the code 988 was set aside nationwide for the Suicide and Crisis Lifeline, which conflicted with Hawaii’s older seven-digit local dialing.
Will Hawaii get a second area code?
Not in the near future. NANPA projects 808 will have enough available numbers to serve the state until at least the third quarter of 2035, so no split or overlay is currently planned.
