We haven’t been able to reach ASTCA for porting instructions, even when trying to place calls to their customer service number. Calling from an American number, the ILD access codes should allow you to call ASTCA for your account number and PIN/ password but the calls simply disconnect when trying to reach their customer service number. The company website does have instructions that an ASTCA customer can reach customer service by dialing 611 from their active phone number. We will update the ASTCA porting instructions when we have new information.

For AT&T landline accounts, your account # is the 10-digit phone number. The PIN is the 4 digits to the immediate right of the phone number in the top right corner of your bill.

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.
