B · Relationships

How it relates to other codes

The codes 616 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 · 1961 906 Upper Peninsula Upper Peninsula split off from 616.
Spawned · 1999 231 Traverse City / Muskegon Northwestern Lower Peninsula split off from 616.
Spawned · 2002 269 Kalamazoo / Battle Creek Southwestern Michigan (Kalamazoo/Battle Creek) split off from 616.
What's changing. No overlay; single code, 10-digit dialing since 2021.
