How it relates to other codes

The codes 731 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?

Split from · 2001 901 Memphis Split from 901; 901 was then restricted to greater Memphis.
What's changing. No overlay. Ten-digit dialing was scheduled by Oct 24, 2021, only where needed for the 988 hotline.
