When making phone calls, you can hide your Caller ID to remain anonymous.
To block your caller ID on a per call basis, add *67 to the number to be called, for example, *67 8436651234
Note: If you are a Verizon or Sprint/T-Mobile customer and wish to block all future calls from passing your caller ID information, use the My Verizon or My Sprint Android app to adjust caller ID settings.
Note: This is a one time use caller ID block. Subsequent calls without the *67 will pass your caller ID information to the called phone.
