If the owner had set it up with Find My Phone they'd be able to display a custom message including whatever contact info they might might like to include. Unfortunately this feature doesn't seem to work if the phone is in airplane mode.

In the past when we've lost phones we just called that number until someone answered.

Turns out the owner didn't know she lost the phone. She thought she left it in her co-workers car (when they got back from lunch). It wasn't until I sent an email to the entire College that she called to inquire about it.
