Yes. In USA and Canada, the phone line gets a name for the caller, sent 
somehow dynamically from the calling phone. On land lines at least. 
There is a service to define what name you want to send when making a 
phone call.

In Europe, you only get a name if you write it yourself in your local 
contact list.
