How to Manually Unblock Phone Numbers
An unblocked phone number allows people to properly screen their calls since the caller's number can be identified. You may also need to unblock your own number if you have chosen to have your phone number automatically blocked through your telephone service provider. If a caller is using services like VoIP or mobile-phone services, your phone number may not show up on caller ID. Using universal codes or third-party programs, you will be able to manually unblock a number.
Unblock Your Own Number
Pick up your phone and wait unto you hear a dial tone.
Dial *82 using your phone's keypad. You will hear the dial tone skip two beats after inputting *82.
Dial your intended phone number. The phone will ring as usual, and the recipient will see your number on their caller ID.
