Did you know you could block the receiving party's Caller ID from displaying your name and number? It's perfect for when you need to make an anonymous phone call. With Caller ID Blocking, your name and number appears either as "Private" or "Anonymous" on the other person's Caller ID displays. Use it to anonymously make phone calls or to protect your unlisted number.
Sometimes, the receiving party blocks calls marked "Private." When this happens, you can temporarily cancel Caller ID Blocking.
Change your Caller ID Blocking default setting
There are two types of Caller ID Blocking available:
- When you sign up for Caller ID Blocking, Caller ID Blocking Per Call will be the default setting.
- This option automatically sends your name and number to the receiving party's Caller ID unit, unless you block the information before you call.
- Caller ID Blocking Per Line automatically blocks your name and number from the receiving party's Caller ID unit, unless you unblock the information before you call.

Note: Caller ID Blocking is automatically disabled for calls made to public emergency hotlines, poison-control lines, and 911 services. Do not attempt to manually disable Caller ID Blocking (such as by dialing *82) for these calls.
Block a single call with Caller ID Blocking Per Call
If you did not sign up for Caller ID Blocking Per Line, you can still activate Caller ID Blocking when you want to block your number from appearing on an outgoing call. Your name and number will be marked "private" or "anonymous" each time you use this feature.
- Listen for the dial tone on your phone.
- Press *67.
- You will hear a confirmation tone, and then a dial tone again.
- After you hear a second dial tone, enter the number you wish to call.
- Your name and number will be blocked for the current call only.
- After you hang up, your next call will display your name and number on the receiving party's Caller ID unless the *67 feature used again.
Note: If the receiving party has Anonymous Call Rejection activated, you will get a message instructing you to un-block your call. In this case, hang up and dial the number directly without using *67.
Unblock a single call with Caller ID Blocking Per Line
To cancel Caller ID Blocking Per Line for one call:
- Lift the receiver and listen for the dial tone.
- Press *82.
- You will hear a confirmation tone, and then a dial tone again.
- Dial the number you wish to call.
- Your name and number will appear on the called party's Caller ID display for that call only.
- After you hang up, your next call will not display your name and number on the receiving party's Caller ID unless the *82 feature used again.
Caller ID Blocking guidelines
- You do not need to have Caller ID on your home phone to use Caller ID Blocking.
- Features such as Call Return that allow the receiving party to return a call to a private caller will do so without giving the private caller's name and number.
