B · Relationships

How it relates to other codes

The codes 316 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?

Spawned · 2001 620 Southern Kansas (outside Wichita) 620 split off from 316 in 2001 and now entirely surrounds it (a "doughnut" pair).
What's changing. No overlay; an enclave surrounded by 620 with no co-located overlay.
