The other area codes laid over 513
Area code 513 does not have Cincinnati to itself. 1 other code — 283 — serves the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
283423 blocks, 22 rate centres, mostly VoIP
Each holds its own blocks and its own carrier mix, so a 513 number and a 283 number from the same street can report different line types. Filtering Cincinnati by area code needs all 2 of them.

Where 513 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Ltl Miami and Newtonsvl 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 513 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 513?
Area code 513 covers Cincinnati, Ohio. It is not the only code there: 283 is an overlay on the same rate centres, so a Cincinnati, Ohio number can start with any of them.
Is a 513 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 513 the split runs 51% mobile, 39% landline and 11% VoIP, so mobile is the most likely single answer.
Which carriers hold 513 numbers?
The largest holders are Verizon Wireless, Onvoy, Cincinnati Bell. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 513 numbers are there?
