Frequently asked about 615
What state is area code 615?
Tennessee. It covers the same area as 615/629.
Can I still get a 615 number?
Only from recycled stock. 781 of the 786 available blocks are already allocated, so new numbers in the area normally come from the overlay codes (615/629).

615 is one of the most complained-about codes in the country – 1,034 FTC complaints in the 33 days to 30 October 2026, 35th of 422 ranked codes. Most of those calls are spoofed: the caller fakes a local-looking number because it gets answered more often. Look up the specific number rather than judging by the code.
Which carrier owns 615 numbers?
