Area code 701


Area code 701 is a telephone area code in the North American Numbering Plan for the U.S. State of North Dakota. It is one of the 86 original area codes created by AT&T in 1947, and continues to be the only area code in North Dakota, and one of twelve states with one only code.
Numbering plan area 701 is divided between the Bismarck and Fargo LATAs, and is one of only a few area codes so divided. The Fargo LATA extends for some distance into northern Minnesota, as far east as Brainerd.
Numbering plan exhaust projections forecast that North Dakota will need a new area code in 2030. About 600 of the nearly 800 possible central office codes have been assigned. The danger of exhaustion comes from the proliferation of mobile services particularly in Fargo, Grand Forks and Bismarck.
