The towns inside area code 585
Area code 585 is not a city code. It covers 78 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 585 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.
New York is split across 21 area codes — 347, 929, 646, 845, 315, 585 and others. By allocated blocks 585 is the 11th largest of them, holding 6% of the New York total.
Where 585 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why W Webster and Churchvl 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 585 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.
