Area code 731 is a telephone area code in the North American Numbering Plan (NANP) for the western part of the U.S. state of Tennessee. The numbering plan area (NPA) includes the cities of Jackson, Tiptonville, Savannah, Union City, Dyersburg, Lexington, Ripley, Martin, Brownsville, Paris, and Bolivar. Area code 731 was created in September 2001 in a split from area code 901, which was the original area code created for the entire state in 1947. NPA 901 has since been restricted for use in the greater Memphis metropolitan area only.
