Tennessee area code questions

How many area codes does Tennessee have?

Tennessee has 8 active geographic area codes in this directory: 423, 615, 629, 729, 731, 865, 901 and 931.

Which area code should I choose in Tennessee?

Start with the first three digits after +1 on the number you want to check. The codes in this directory are associated with places including Chattanooga, Nashville, Jackson, Knoxville, Memphis, and Columbia. The listed places are examples, not a complete map of each code’s boundaries.

Which Tennessee area codes share coverage?

NANPA groups these codes in shared numbering complexes: 423 / 729; 615 / 629. Members can serve overlapping areas; being in the same complex does not necessarily mean identical geographic boundaries.

How do I dial a number in Tennessee?

Open the individual area code to check its local dialing rule. For a phone lookup, enter +1 followed by the three-digit area code and the seven-digit number. A state or area code alone is not enough to look up a particular number.

Does an area code from Tennessee show where the caller is?

No. An area code describes a number’s assigned region. People can keep numbers after moving, use them while traveling, or place internet-based calls. Caller ID can also be spoofed, so the code does not confirm the caller’s location or identity.
