You’ll need a Number Transfer PIN (and required account info) to transfer your number from AT&T to another service provider.
Heads up:
Request your Number Transfer PIN close to the time you’ll submit the transfer request to the new provider. You can use a single Number Transfer PIN for all numbers that are on the same account. The Number Transfer PIN will expire four days after you request it. If you need a new one, you can ask for another by following the same steps.

FYI: AT&T employees can’t generate a Number Transfer PIN on your behalf.
Call *PORT. Follow the prompts to get your Number Transfer PIN sent to you via text. You’ll need your account passcode to generate the Number Transfer Pin when calling *PORT.
