Find any 731- phone number in Tennessee
The 731 area code is part of the North American Numbering Plan (NANP), which is an international system that designates a 3 digit code to serve a specific geographic area. Each area code is related to a particular geographic area, such as a state, province or country, although some area codes subdivide larger geographic areas where there is a large population.
In the case of the 731 area code, it serves west-central Tennessee, including the cities of Jackson, Dyersburg, Martin, and Union City. It was created in the middle of 2001, when all of the area within west-central Tennessee, formerly served by the 901 area code, was divided in two. The 731 area code serves the western half of the geographically split region, while the 901 area code serves the eastern half. The 731 area code was created as a result of the area's growing population and the need for more telephone numbers to distribute.
