The other area codes laid over 972
Area code 972 does not have Dallas to itself. 3 other codes — 214, 469, 945 — serve 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.
2145,315 blocks, 23 rate centres, mostly mobile
4697,778 blocks, 42 rate centres, mostly mobile
9453,038 blocks, 41 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 972 number and a 214 number from the same street can report different line types. Filtering Dallas by area code needs all 4 of them.
972 is not confined to Dallas itself: its blocks sit across 43 rate centres, named in the table below.
