How it relates to other codes

The codes 304 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?

Overlay · 2009 681 West Virginia (overlay) 681 overlays all of West Virginia; a proposed split was rejected in favor of an overlay.

What's changing. Overlaid by 681 since 2009; 10-digit dialing mandatory statewide.
