The towns inside area code 606
Area code 606 is not a city code. It covers 126 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 606 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.
Kentucky is split across 5 area codes — 502, 270, 859, 606, 364. By allocated blocks 606 is the 4th largest of them, holding 20% of the Kentucky total.
Where 606 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Barbourvl and Mt Vernon are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 606 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.
