The towns inside area code 507
Area code 507 is not a city code. It covers 228 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 507 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.
Minnesota is split across 7 area codes — 507, 218, 612, 320, 651, 763 and others. By allocated blocks 507 is the largest of them, holding 20% of the Minnesota total.
Where 507 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why St Peter and Redwoodfls 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 507 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.
