Area code 907 is the sole telephone area code in the North American Numbering Plan (NANP) for the U.S. state of Alaska.

Alaska was assigned its area code in 1956, when the first commercial submarine cable was opened for traffic in December.

Telephone service to Alaska was provided from the contiguous United States via a terrestrial line to the town of Juneau since 1937,^[1] The Alaska submarine cable was opened for traffic on December 11, 1956,^[1] linking Port Angeles, Washington, with Ketchikan, Juneau, and Skagway in Alaska

The Alaska numbering plan area is geographically the largest of any in the United States. It is the second-largest in 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 twelve remaining area codes serving an entire state. It is not projected to be exhausted until after 2049.

The small southeastern community of Hyder is not served by the area code, but by the Canadian overlay complex 236/250/257/672/778 from the Stewart, British Columbia rate center.^[2]

Prior to October 2021, area code 907 had telephone numbers assigned for the central office code 988. In 2020, 988 was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which created a conflict for exchanges that permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021.^[3]

Note: Dashes in the “Introduced” field indicate the prefix was in use before February 4, 1994.
