Caller ID is built into the very guts of the Droid 2. That’s why you see the phone number and at times the caller’s name every time you get a call. And when you call someone, he sees your phone number as well. There’s a way to block your number from being displayed, although as with call forwarding, you can’t do it on the phone, but have to go through Verizon. Check your Verizon Wireless account to make sure you have the capability. Then when you want to block your phone number from being displayed when you make a call, tap *67, and then make the call. Your number won’t be displayed on the receiving end. Instead, the person will see “Private” or “Anonymous” or something to that effect. When the call ends, Caller ID is deactivated; you’ll have to tap *67 to enable it on your next call.
To turn off outgoing Caller ID for all your calls, log into your Verizon Wireless account, and in the “Add/Change features” section, turn on the checkbox for Caller ID Blocking.
