A brief description of Tennessee Area Codes is given below:

It was formed as a result in split of area code 615 in 1995.  Code 423 provides telephone services to two different areas located at the Eastern region of the Tennessee State of United States.

It was created as a result in split of area code 901 in 1954. Major area served by the code 615 is Nashville City. The Code originally served the Middle and East regions of the State.

This area code was created in 2001 for providing numbering relief to area code 901. The Code 731 provides telephone services to the Tennessee State of United States. The particular code was created as a result in split of area code 901.

It was created in 1999 for providing numbering relief to area code 423. Area Code 423 was getting exhausted and was running out of available phone numbers and so there was no other way than splitting the exhausted area.

This is one of the original area codes created by NANP (North American Numbering Plan) in 1947. Initially, this code had to serve the entire State. However with the passage of time and because of area splits - the Code is now serving only the Southwest corner of the State.

It was created as a result in split of area code 615 in 1997. The Code 931 provides telephone services to the Middle region of the state. However the Nashville City is served by area code 615 though it is located in middle of the State.
