No matter your account type, your account number is easy to find!


Prepaid accounts

If you have a Pay in Advance (prepaid) account, your mobile number is your account number. How easy is that?


Postpaid accounts

If you have a postpaid account, like one of our Magenta plans, you can find your account number in My T-Mobile.

  1. Log in to My T-Mobile​ with your T-Mobile ID and password.
  2. View your account number in the upper-right corner of the screen.
