A “Number Transfer PIN”, or “NTP” for short, is a pin code that can be generated on the fly to authorize a port-out of your phone number to another carrier. It’s standard practice now across the industry, and while T-Mobile was a bit late to the game, they now require an NTP to be generated when porting your number out to another carrier.
Why is a Number Transfer PIN necessary?
The 6-digit PIN code is a way to make sure the port-out request is legitimate. The idea is that if a bad actor wanted to port out your number, they would need full access to your T-Mobile account before a port would complete. Both AT&T and Verizon also use the same process.
T-Mobile added their NTP requirement in April of 2022. In order to port your number to another carrier like AT&T or Verizon, you’ll need to generate one. This code is then given to your new carrier as authorization for the port-out. In order to generate an NTP code, you must be the primary account holder on the T-Mobile account.
Generate a PIN in the T-Mobile app
There are two methods to generate a transfer PIN. Remember, you need to be signed in as the primary account holder to generate a pin for a line.
The first method uses the official T-Mobile app. This section was updated August 2024 to account for the new “T-Life” version of the app. The new app makes things a little more complicated. Here’s how to get the PIN.
Step 1: Open the T-Mobile/T-Life app and go to the “Manage” tab at the bottom. Sign in using the primary account holder’s login. Near the top, tap “See plans >”.
Step 2: You should now be on the “My account” page. Tap any of the lines in your list to go to a “Device details” page.
Step 3: On this “Device details” page, scroll all the way to the bottom, and under “Additional tasks”, choose “All account settings”.
Step 4: Choose the number you’re wanting to port-out with the drop-down box at the top. Once chosen, tap “Line Settings” near the bottom of your screen, then choose “Request a transfer PIN”. Tap that to generate your NTP code.
Generate a PIN using the T-Mobile website
The second method of generating a transfer PIN is to use the My T-Mobile website located at https://my.t-mobile.com.
Step 1: Open the My T-Mobile website on your device. Log in using the primary account holder’s login. Once you’re signed in, hover over “My account” at the top right of your screen and choose “Profile”.
Step 2: Next, find “Line Settings” in the list of options and click it.
Step 3: On the Line Settings page, be sure the number you wish to port out is selected at the top, then click “Request a transfer PIN” at the bottom of the list of options.
