How to Make a Cell Phone Number Unknown

If you need to call someone who you don't want to get your cell phone number, you can block your caller ID. Depending on the carrier, your number will show up as Unknown or Restricted on the other end. You can block caller ID on a per call basis, or have your carrier permanently block caller ID on all calls.

Dial *67 on your cell phone's dial pad.

Dial the number you want to call.

Press the "SEND" or green phone button.
