The towns inside area code 931
Area code 931 is not a city code. It covers 100 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 931 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 931 is the 5th largest of them, holding 13% of the Tennessee total.
Where 931 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Clarksvl and Shelbyvl 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 15% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 931 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.
