The towns inside area code 865
Area code 865 is not a city code. It covers 33 separate rate centres — billing areas, each its own local calling zone. The largest of them are named in the table below.
That matters twice over. A call between two 865 numbers is not necessarily a local call, because they can sit in different rate centres. And a code this wide narrows a subscriber to a region rather than a town.
Tennessee is split across 7 area codes — 423, 615, 901, 865, 931, 731 and others. By allocated blocks 865 is the 4th largest of them, holding 14% of the Tennessee total.
Where 865 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Seviervl and Jeffersncy are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, Onvoy, has 14% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 865 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 865?

Is a 865 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 865 the split runs 42% mobile, 43% landline and 14% VoIP, so landline is the most likely single answer.
Which carriers hold 865 numbers?
