Area code assignments in North Dakota follow the North American Numbering Plan (NANP), which has been in effect since 1947. As the state's population and demand for phone numbers grew — driven by the rise of cell phones, fax machines, pagers, and VoIP lines — regulators either split existing area codes geographically or added overlay codes that share the same territory. That's why North Dakota now has 1 codes: 701.
When you receive a call from a North Dakota number, the area code tells you only where the number was originally assigned. Because of Local Number Portability (LNP), which took effect in 2003, callers can keep their phone numbers even when moving across state lines. So while a 701 number was once assigned in North Dakota, the person calling you could be anywhere in the US today.

Phone number format in North Dakota
All North Dakota phone numbers follow the standard 10-digit NANP format: (NPA) NXX-XXXX. For local calls within North Dakota, you typically need to dial the full 10-digit number — even for calls within the same area code — because of mandatory 10-digit dialing imposed by the FCC for areas with overlay codes (most of North Dakota's territory). For long-distance calls within the NANP, dial 1 + area code + 7-digit number.
