How to Unblock Someone's Number on an AT&T Phone

By Mandy Slake

AT&T's call-blocking service allows users to block calls from individual numbers. The user calls a special access number, then adds the block through the phone's keypad. When the blocked caller calls the number, they hear a message that the number is not accepting calls. When the user wants to unblock the number, they can remove the block from the same menu.

Dial "*60" from a touch-tone phone to enter the selective-call-rejection system.

Press the "*" button to unblock a number.

Dial the number you wish to unblock.

Press the "#" key to confirm you want to unblock the number.
