The address is 682 W. Oakleaf Ln. Baldwin, MI 49304. I don't know your situation, but if you have your man's MDOC number you just write to him there with the MDOC number and he will get it. They will not give you any info on the phone if you try to do that. Baldwin is 90-120 days from what I learned. My ex is back in there again and he was out for all of 2.5 months. He will never learn cuz he just does his time and then gets out and screws up again. Good luck to you!
