T-Mobile Prepaid Porting Instructions
Your 11 digit phone number (1-***-***-****) is the account number for T-Mobile Prepaid. The passcode is your 4-digit PIN (the same PIN used when calling customer service). If you don’t have a PIN you can set one up by calling 611 from your T-Mobile phone. Respond “No” when asked if you want to refill and then choose “Manage my account” followed by “Change my account PIN”. If you forgot your PIN number or need other help call the porting department.

Check coverage before you port
T-Mobile Prepaid runs on the T-Mobile network, so the coverage you get at your address is T-Mobile coverage. Check it on T-Mobile’s own coverage map before you start the transfer.
Your right to keep the number is federal, not a carrier policy. The rule is the FCC’s: Portability: Keeping Your Phone Number When Changing Service Providers.
