The other area codes laid over 615
Area code 615 does not have Nashville to itself. 1 other code — 629 — serves the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
6291,929 blocks, 44 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 615 number and a 629 number from the same street can report different line types. Filtering Nashville by area code needs all 2 of them.

Where 615 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Goodletsvl and Hendersnvl are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, Verizon Wireless, has 13% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 615 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 615?
Area code 615 covers Nashville, Tennessee. It is not the only code there: 629 is an overlay on the same rate centres, so a Nashville, Tennessee number can start with any of them.
Is a 615 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 615 the split runs 41% mobile, 48% landline and 11% VoIP, so landline is the most likely single answer.
Which carriers hold 615 numbers?
