About Hawaii Area Codes

Hawaii (HI) uses 1 telephone area code to serve its residents and businesses. With an estimated population of 1,826,327, Hawaii is one of the smaller states in the North American Numbering Plan (NANP). The state is primarily in the Hawaii-Aleutian Time Zone (HST). The current local time in Hawaii is 11:37 PM.

The largest cities in Hawaii include Honolulu (pop. 820,987), East Honolulu (pop. 47,540), Pearl City (pop. 45,605), Hilo (pop. 45,056) and Waipahu (pop. 39,469) . Hawaii has 5 counties spread across its territory. Each area code in HI covers a geographic region of the state, with some areas using overlay codes that share the same geographic territory as an existing area code.

When calling a Hawaii phone number from outside the area code, you must dial the full 10-digit number: the 3-digit area code followed by the 7-digit local number. Many parts of Hawaii now require 10-digit dialing even for local calls due to overlay area codes and the nationwide 988 Suicide & Crisis Lifeline implementation.
