Many people choose to withhold caller ID information when they place outgoing calls. By requesting this call-blocking service from your telephone service provider, your caller ID information will appear as "Anonymous" when you make outgoing calls on your phone. At times, you may want to "unhide" your blocked information so that it will appear on caller ID displays. You can unhide your information by entering a code on a call-by-call basis.
Pick up your phone's handset.
Wait for a dial tone.
Press "*82" on your phone's keypad.
Enter the phone number you want to dial. Your call will automatically connect and your caller ID information will appear on the call recipient's caller ID display.
