AT&T GoPhone Account Number, PIN & Port Out

Call the AT&T porting department to get your account number. The account number is NOT listed in the online account. The passcode is your 4-digit PIN.

Last updated September 25, 2026

This is a brief overview of AT&T GoPhone and how to get the information you will need if you wish to port your phone number out to a different company. You can use the AT&T GoPhone Porting Instructions below to get your AT&T GoPhone account number and transfer PIN.

What network does AT&T GoPhone use?

AT&T GoPhone runs on the AT&T network.

AT&T GoPhone Porting Instructions

Your AT&T GoPhone Account Number is NOT listed in your online account. It is not your phone number either. You must call the AT&T porting department or customer service to get your account number. Then, say “more options” when you hear the automated system. Press “0” to get to a live human representative. You can ask them for the account number. They also can text your 4-digit PIN to your active AT&T GoPhone if you need it. Since GoPhone accounts do not use an SSN, any carrier you are porting into must enter all zeroes (0’s) if their Port Request form requires a Social Security Number. Be sure to verify the name and address on file with GoPhone while you are on the line to prevent a Port Request failure.

GoPhone was previously the name of AT&T’s prepaid phone service. AT&T acquired the company in 1995 and discontinued the brand after July 2017.

Check coverage before you port

AT&T GoPhone runs on the AT&T network, so the coverage you get at your address is AT&T coverage. Check it on AT&T’s own coverage map before you start the transfer.

Your right to keep the number is federal, not a carrier policy. The rule is the FCC’s: Portability: Keeping Your Phone Number When Changing Service Providers.

Working a counter? The AT&T GoPhone transfer PIN lookup puts these steps on one screen and texts them to the customer.
