Let's go over how to transfer your number from T-Mobile.

To transfer your number from T-Mobile, you’ll need:

  1. Your T-Mobile account number — this can be found on the top right corner of your bill or in your online account portal.
  2. The address found on your current bill
  3. Your Transfer PIN (port-out pin). There are a couple of methods to obtain your Transfer PIN. See below for more details:
    1. T-Mobile App:
      1. Login → Account → Profile Settings → Line Settings → Request a Transfer PIN
    2. T-Mobile.com:
      1. Login → My Account (or your name) → Profile → Line Settings → Request a Transfer PIN → Get a Transfer PIN

Transfer PIN

Your Transfer PIN is created by T-Mobile at your request. It is not your current security PIN on your account or the security code used to access your phone.
