If you call the toll-free voice mail access number from your AT&T phone, the carrier's voice mail system will read the mailbox number from the phone's caller ID. When you call the AT&T voice mail system from a phone other than your AT&T line, the system will prompt you to enter the number manually. The voice mailbox number identifies your voice mail box on the system.


Step 1

Dial (888) 288-8893. The system will only prompt you for a mailbox number when you are calling from a phone other than your AT&T phone.
