Since the dawn of caller ID, individuals have wanted to "spoof" their call ID—a process that makes the ID look different to the person receiving the call. While the "_67" trick—entering "_67" before dialing a number so your ID will not display to the person you are calling—is well known, many people will not answer calls when the caller ID displays "Caller Blocked" or "Restricted ID." However, it is possible to completely spoof your ID and trick someone into thinking you are someone else.
