Is it possible to track down someone through their apple id and or iphone?

My boyfriend and I are in a huge fight and we aren't talking to each other and i tried contacting him through his friends and even called him. I want to track him down to know where he is and if hes okay without him knowing. Please answer quick

A court order through his wireless company is the only way to track down a location of a phone.

Only the service can track it now.
