731 Area Code – Jackson, Tennessee: Location, Time Zone & History

West Tennessee's 731 traces back to area code 901, which had covered the entire state of Tennessee and later all of Tennessee west of the Tennessee River since 1947. As Memphis grew, planners carved out the surrounding counties outside the metro area into a new code, put into service February 12, 2001, leaving 901 restricted to Memphis proper. Some secondary sources cite September 2001 instead, which likely reflects the later mandatory ten-digit dialing cutover rather than the original split date. No overlay has been layered onto 731 since.

Centered on Jackson, the numbering plan area also reaches Dyersburg, Union City, Martin, Paris, Brownsville, Savannah, and Tiptonville, bordering codes 901, 270, 931, 662, 573, and 870. Its economy runs on I-40 logistics and distribution warehousing around Jackson, cotton, soybean, and corn agriculture, automotive manufacturing, and healthcare.
