How to Block Caller ID

Using Google Voice

1. 
   Understand what using Google Voice will do. Google Voice assigns a new, 10-digit phone number to you; this number is used whenever you use Google Voice to make a call.

   1. While using Google Voice won't prevent the person you're calling from seeing your Google Voice number, they won't be able to see your phone's actual number even if they have unmasking services or apps installed.
   2. Using Google Voice is a good way to get through to a person who screens blocked numbers without having to reveal your actual number.
