Area code 907
Despite having telephone service to the contiguous US via a terrestrial line from Juneau since 1937, Alaska was not included in the North American Numbering Plan (NANP) until after the Alaska submarine cable was opened for traffic in 1956. The Alaska numbering plan area (NPA) was assigned the area code 907, and entered service in 1957.
The Alaska numbering plan area is geographically the largest of any in the United States. It is the second-largest on the NANP and on the entire North American continent behind 867, which serves Canada's northern territories. Because the Aleutian Islands of Alaska cross longitude 180, the Anti-Meridian, 907 may be considered to be both the farthest west and the farthest east of all area codes in the NANP. Due to Alaska's low population, 907 is one of only 12 remaining area codes serving an entire state. It is not projected to be exhausted until 2029.
Many calls within Alaska are long-distance calls and must be dialed with the leading 1-907, except for cellphone services. Local calls and cellphone calls for long-distance service within Alaska, only require seven-digit dialing.
At the time of its creation, area code 907 was one of the two longest area codes to dial on a rotary phone, taking 26 pulses to dial out in an era before the first touch tone phones. This is the same number of pulses as Hawaii's area code 808, introduced the same year.
