The other area codes laid over 703
Area code 703 does not have Arlington, Virginia to itself. 1 other code — 571 — 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.
5716,574 blocks, 19 rate centres, mostly mobile
