The towns inside area code 740
Area code 740 is not a city code. It covers 187 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 740 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.
Ohio is split across 14 area codes — 740, 440, 937, 614, 513, 330 and others. By allocated blocks 740 is the largest of them, holding 12% of the Ohio total.
Where 740 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Steubenvl and Stclairsvl 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 740 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Where is area code 740?

Is a 740 number a mobile or a landline?

Which carriers hold 740 numbers?
