# The 940 Area Code: North Texas Communications

The 940 area code serves North Texas, covering a significant region that includes the cities of Denton, Lewisville, and the northern suburbs of the Dallas-Fort Worth metroplex. Established in 1997 through a split of the original 817 area code, the 940 area code was created to accommodate the rapidly growing population and increasing telecommunications demand in North Texas. This region has experienced substantial development over the past two decades, with suburban expansion and economic growth driving the need for additional phone numbers. The 940 area code is one of several overlapping and adjacent area codes in the Dallas-Fort Worth region, reflecting the area's continued growth and the finite nature of available phone numbers.

The North American Numbering Plan (NANP) is the standardized system that designates and manages area codes like 940 throughout the United States, Canada, and other North American territories. This system organizes telephone numbers into a hierarchical structure, with the three-digit area code forming the first part of a ten-digit phone number. Area codes are assigned by the North American Numbering Plan Administrator (NANPA), a neutral third party that allocates codes based on projected telecommunications needs and geographic boundaries. When regions exhaust their available numbersas North Texas didthe NANP creates new area codes through splits or overlays, ensuring that growing communities have sufficient phone numbers for residents and businesses while maintaining the integrity of the numbering system.
