Green light phones

Emergency phones, identified by a green light above the phone, are deployed outdoors throughout the MSU campus and indoors in residence halls and in select classroom buildings. The phones feature one-touch 911-calling and selected locations include emergency speakers that can provide audible messages to the MSU community. Green light phones are managed by the MSU Police.


If you need immediate emergency service or have a general question about IPF, call (517) 353-1760. For routine or special services submit an online service request.
