Why Metro Murfreesboro Has 2 Area Codes
When a region uses more numbers than one code can hold, new codes are overlaid on the same territory rather than forcing anyone to change numbers. Metro Murfreesboro now uses 615 and 629: same neighborhoods, ten-digit dialing, and every one of them covered by its own guide above.

How Tennessee Got Its Codes
Every Tennessee area code, in the order it entered service. Splits carved new regions; added codes overlay existing ones, which is why ten-digit dialing is standard.

|---|---|---|
| 1947 | 901 | One of the original area codes of 1947 |
| 1954 | 615 | Original assignment for its region |
| 1995 | 423 | Added to the 615 region |
| 1997 | 931 | Split from 615 |
| 1999 | 865 | Split from 423 |
