Find any 615- phone number in Tennessee

The 615 area code, which is located in the state of Tennessee, is part of the North American Numbering Plan (NANP). It was one of the original area codes established in 1947 when the NANP was created and was assigned to the state of Tennessee. In 1997, a second area code—the 629 area code—was added to the 615 area code due to an increased demand for telephone numbers.

The NANP is the internationally recognized numbering plan for the US and Canada. It works by assigning an area code to a geographic area and then dividing up those area codes into smaller regions. For example, the 615 area code encompasses Nashville, which is the capital of Tennessee. This area code is also used for other major cities, including Lebanon, La Follette and Murfreesboro. Additionally, it can be used to identify callers from surrounding counties and towns.
