Area code 701 covers the entire state of North Dakota. Established in 1947 as one of the original area codes, it remains one of the few single-area-code states in the U.S. The code serves cities such as Fargo, Bismarck, Grand Forks, and Minot. With a small, stable population and vast geographic spread, 701 has been sufficient to meet the state’s telecommunications needs for decades. It is a point of state pride and identity, often used in marketing and local branding. 701 reflects North Dakota’s unified, rural character and its steady growth in industries like agriculture, energy, and education.
