How it relates to other codes

The codes 806 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 · 1957 915 El Paso 806 was flash-cut from the northwestern (Panhandle) portion of 915 in 1957; it also absorbed a small piece of 817.
