The towns inside area code 515
Area code 515 is not a city code. It covers 98 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 515 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.
Iowa is split across 5 area codes — 515, 712, 641, 319, 563. By allocated blocks 515 is the largest of them, holding 24% of the Iowa total.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 515 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.
