How to Figure Out My Mailbox Number for AT&T

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.

Step 2

Dial the 10-digit phone number for your AT&T phone. The system will prompt you for your voice mail password.

Step 3

Dial your voice mail password. The default password is "111111."

Tip

If you have forgotten your password, call (800) 288-2747 to have the password reset.

Warning

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.
