Honolulu, HI Area Code

Area code serving Honolulu

Honolulu sits in Hawaii, part of the West region and the Hawaii–Aleutian Time zone. Its area code is 808, which covers the entire state of Hawaii, all islands. 808 has no overlay today, so every Honolulu landline and mobile number with a local code starts with 808.

808 has served the area since 1957. If the region runs low on numbers, regulators will most likely add an overlay code on top rather than split the area, which would make 10-digit dialing mandatory.

Getting a Honolulu phone number

Any new landline, mobile or VoIP number from a local carrier in Honolulu gets the 808 area code. Numbers come from the blocks each carrier holds in the area; a number ported in from elsewhere keeps its original area code, so you may also see out-of-state codes locally.

Dialing in Honolulu

Honolulu is covered by the single area code 808 with no overlay, so some local calls may still connect with seven digits. Dialing all 10 digits (area code + seven-digit number) always works and is the safest habit. From outside the US, dial +1, then the area code and number. See 10-digit dialing and overlay area codes for the background. For every code in Hawaii, visit the Hawaii area codes page.
