The easiest way to try to trace an unknown phone number is to perform an internet search. Look here to access an online phonebook http://www.whitepages.com.
The best way is to find phone look up services like what you can get on http://trackphoneuser.com/. This can greatly help in determining the location and identity of the caller.
