The other area codes laid over 463
Area code 463 does not have Indianapolis to itself. 1 other code — 317 — 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.
3175,657 blocks, 37 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 463 number and a 317 number from the same street can report different line types. Filtering Indianapolis by area code needs all 2 of them.

Where 463 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Noblesvl and Shelbyvl 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 463 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 463?
Area code 463 covers Indianapolis. It is not the only code there: 317 is an overlay on the same rate centres, so a Indianapolis number can start with any of them.
Is a 463 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 463 the split runs 40% mobile, 29% landline and 31% VoIP, so mobile is the most likely single answer.
Which carriers hold 463 numbers?
The largest holders are Onvoy, AT&T Wireless, Verizon Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 463 numbers are there?
