The other area codes laid over 223
Area code 223 does not have Harrisburg, Pennsylvania to itself. 1 other code — 717 — 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.
7176,286 blocks, 107 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 223 number and a 717 number from the same street can report different line types. Filtering Harrisburg, Pennsylvania by area code needs all 2 of them.

Where 223 numbers are concentrated
