Area code 701 is a telephonearea code in theNorth American Numbering Plan (NANP) for theU.S. State ofNorth Dakota. It is one of the 86original North American area codes created byAT&T in 1947, and continues to be the only area code in North Dakota, one of eleven states with only one area code.

Numbering plan area 701 is divided between theBismarck andFargoLATAs, and is one of only a few divided area codes. The Fargo LATA extends for some distance into northernMinnesota, as far east asBrainerd.

Numbering plan exhaust projections forecast that North Dakota will not need a new area code until 2029.[1] About 730 of the nearly 800 possible central office codes have been assigned.

Being the sole area code in North Dakota,seven-digit dialing is in effect for all calls within the state. The situation was threatened in 2020, when it was anticipated that the state had to transition to always dialing ten digits, because of the implementation of a short-code (988) for theNational Suicide Prevention Lifeline, because that code was assigned as a central office prefix to an office (CLLI codeBSMRNDJC) in Bismarck. However, the local telephone administration decided to discontinue this central office code, and return it to the NANP Administrator.[2] This action removed the need to implementten-digit dialing in area code 701, until relief is necessary in the future.
