How to Get Your Porting Information from T-Mobile

If you're transferring your number from T-Mobile to another service provider, you’ll need your account number, a Temporary Port Out PIN (TPOP), and a recent T-Mobile bill. T-Mobile also requires that Port Out Protection is turned off before your number can be moved. This guide walks you through everything you need.

1. How to Find Your T-Mobile Account Number

Your T-Mobile account number appears in your online account or the T-Mobile app.

2. How to Generate Your T-Mobile Temporary Port Out PIN (TPOP)

You must provide this PIN to your new provider to complete the transfer.

Before generating your PIN

• Only the Primary Account Holder can generate the TPOP
• Port Out Protection must be disabled for the line
• You must generate the TPOP while using the T-Mobile network (not Wi-Fi)
• Turn off any VPN or private relay services (such as iCloud Private Relay)

What you’ll need for the transfer

• Your T-Mobile account number
• The Temporary Port Out PIN
• The account PIN / passcode
• Government accounts must contact T-Mobile directly for assistance

Troubleshooting Issues Generating Your PIN

If you're having trouble generating the TPOP:

  1. Use the device with the active SIM/eSIM

  2. Turn OFF Wi-Fi and ensure you’re on the T-Mobile network

  3. Turn off VPNs or private relay (such as iCloud Private Relay)

  4. Try again later if you receive an error message

  5. Only the Primary Account Holder can generate the PIN

If you're still stuck, contact T-Mobile at 1-800-937-8997.
