AT&T Postpaid Porting Instructions
The account number for AT&T postpaid accounts will be on the customers bill (it is NOT the phone number). The password will be your online password. For bundled accounts, the account number will be a 12-digit number under your wireless account summary. Also, (only for bundled bills) you will need to call AT&T customer service for the passcode. The passcode will be a 4-digit PIN number that AT&T will provide to you.
