The other area codes laid over 728
Area code 728 does not have West Palm Beach, Florida to itself. 1 other code — 561 — 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.
5616,296 blocks, 8 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 728 number and a 561 number from the same street can report different line types. Filtering West Palm Beach, Florida by area code needs all 2 of them.
