1. Reverse Phone Lookup
T-Mobile, Verizon, and AT&T

2. Verizon
Verizon phone trace is very useful if you are receiving calls
that you no longer want, or that could be particularly
threatening or harassing to you or your family. Keep in mind
that while Verizon will do its best efforts to trace the call
after it is made, there are no guarantees that this service
will work, and usually it takes more than one abusive phone
call for a case to be opened with Verizon regarding a
harassing phone call issue.

3. AT&T
If you have pieces of information about a person who called you, but still
no name behind the caller, try the AT&T Directory Assistance website. This
method works best for home phones, although cell phones have been
known to be in this directory as well. Navigate to http://
www.corp.att.com/directory/ and type in as much information as you
know about your caller. Once you are done, click on search to see if
anything comes up.
