Set up your Customer PIN/Passcode

Whether it's been a few months since updating your Customer PIN/Passcode and it's time for a change, or if you've never set one up, we have you covered!



Set up your PIN/Passcode

We use the Primary Account Holder's (PAH) PIN/Passcode to verify their identity when they contact Care.

  • Only the PAH can set the PIN/Passcode used for verification when calling Care.
  • When a Non-PAH sets a PIN/Passcode through My T-Mobile, it's not used for caller verification with Care.
  • The PIN/Passcode is not the same as the password you use to log in to My T-Mobile.


If you haven't set up a PIN/Passcode, you'll be prompted to set one when you log in to My T-Mobile.


  1. Log in to My T-Mobile.
  2. Choose a verification method (Text message or Security questions).
  3. Click Next.
  4. Follow the prompts based on the verification method selected. Once complete, you can set up your PIN/Passcode.
  5. On the Set Your PIN/Passcode screen, enter the desired PIN/Passcode and click Next. You will be directed to the My T-Mobile home page.
