The other area codes laid over 447
Area code 447 does not have Danville to itself. 1 other code — 217 — 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.
2175,478 blocks, 265 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 447 number and a 217 number from the same street can report different line types. Filtering Danville by area code needs all 2 of them.
447 is not confined to Danville itself: its blocks sit across 119 rate centres, named in the table below.

Where 447 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Quincy and Jacksonvl 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 447 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.
