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.
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.
Dial the 10-digit phone number for your AT&T phone. The system will prompt you for your voice mail password.
Dial your voice mail password. The default password is "111111."
If you have forgotten your password, call (800) 288-2747 to have the password reset.
If the system tells you the voice mailbox number is incorrect, it means the voice mail box was not set up correctly. Contact AT&T technical support to resolve the issue.
