There are 123 Blue Light phones and 485 indoor emergency phones on campus. For direct connection to Cornell Police, lift the receiver or press the button. Use the phones when you are lost, having car problems, want to report a suspicious incident or a medical emergency, or for any other kind of assistance or information. As soon as the connection is activated, the location of the phone is displayed on the Cornell Police switchboard. If a caller doesn't or can't speak, an officer is immediately dispatched to the phone site.
Note: if you're calling to report an emergency on a phone at the entrance to a residence hall, push the "on" button, then press 911.
