History of the 615 Area Code

The 615 area code was created in 1954 as part of the North American Numbering Plan. Originally, it covered the entire state of Tennessee. However, due to the increasing demand for telephone numbers, the area code underwent several changes:

  • In 1995, area code 423 was created to serve the eastern part of Tennessee, reducing the coverage of 615.
  • In 1997, area code 931 was introduced to serve the western and southern parts of the original 615 area.
  • In 2015, area code 629 was introduced as an overlay to area code 615.

These changes were implemented to accommodate the growing population and the proliferation of mobile devices. For more historical details, visit the North American Numbering Plan Administrator (NANPA).
