Caller ID is a combination of two distinct services that you can subscribe to separately or together.
Calling Number Delivery
This displays the number of the person calling you either on your phone or on a special display device (sold separately). Caller Number Delivery stores numbers on your phone so you can return calls when you wish. If a “Private” or “Anonymous” call appears on your screen, the caller may have blocked the display of their number by pressing *67 before placing the call. If “Out of Area,” “Unavailable” or “Unknown” appears, the caller is in an area that does not support Calling Number Delivery services.
- Purchase a Caller ID Unit or use a special display phone.
- Wait until the phone completes its first ringing cycle for the number to appear.
Things to Remember
- All phone users can block the delivery of their phone numbers on a per-call basis. To block delivery of your number, dial *67, wait for the dial tone, and then dial the number you are calling. Your call will then be classified as "Anonymous" and the number you are calling from will not be available to Caller ID units. Be aware that some locations block "Anonymous" calls and do not allow them to ring through. In these cases, you will hear a recorded message.
- If your line is equipped with per-line blocking, you can disable this block on a per-call basis by pressing *82 (rotary phone users need to dial 1182) before you dial your call. This feature turns off per-line blocking for only the call placed after *82 or 1182 is dialed and will result in your number being received by subscribers of Caller ID.
Calling Name Delivery
Calling Name Delivery works like Calling Number Delivery except that it delivers the name of the caller. The features and limitations associated with Calling Number Delivery apply.
