How to block caller ID spoofing

Updated July 19, 2017

Caller-ID spoofing is the process of changing the name that comes up on another person's phone when you call them. Caller-ID spoofing software can change the Caller-ID that appears to anything the user wants. One good way to block such practices is to use a service that reveals the true number of the caller.

Visit a website like Trapcall.com.

Click on "Try Trapcall Free."

Click on "Start free trial." Fill out your information in the boxes once the next page loads. Click "Create Account."

Deny a call that you get that may be caller-ID spoofed. Trapcall will then send you the true number of the caller.
