R L & Co (907) 276-1962
Ten-digit dialing is required in Alaska, since many calls within the state are classified as long-distance phone calls. People therefore must often guess if they need to dial 1+907 or not (if they don't know the actual location of the business / person they are calling).
Area code 907 is the largest area code (in terms of land area served) in the U.S., and is second only to Canadian area code 867 among codes in the North American Numbering Plan. Since the Aleutian Islands of Alaska cross longitude 180 (also known as the Anti-Meridian), 907 can be considered to be both the farthest west and the farthest east area code in the NANP. It was also tied with 808 as the longest area code to dial on a rotary phone (taking 26 pulses to dial out) until the proliferation of touch tone phones and the opening up of area codes previously unused within the NANP.
