About Area Code 731
Area code 731 is a North American Numbering Plan (NANP) area code that has been in service since 2001. It is administered by NANPA on behalf of the FCC and serves the Tennessee region anchored on Jackson.
731 is currently a single-coverage geographic area code with no overlays. This means a 7-digit number in this area code is unique within its rate centers, though best-practice is always to dial the full 10-digit number when contacting a 731 line.
Mobile numbers in 731 are portable: a person who moved away from Jackson may still carry a 731 mobile number on their device. If you receive an unexpected call from a 731 number, run it through the reverse lookup tool above for the most accurate, free identification.
