How it relates to other codes

The codes 701 was split from, spawned, or shares its area with. A split divides the map and changes some numbers; an overlay shares the same ground and changes none — what's the difference?

What's changing. No overlay. Single statewide code; seven-digit dialing still in effect. Relief projected around 2029 (re-check NANPA).
