How can I prevent fraudulent porting of my phone number?

My friend's T-Mobile number got ported out and the fraudulent porting happened with just his account number and address.

Do you have a PIN for locking my account?

If so, how can I set it up?

Good morning @perxam‌!  That's a terrible thing to read about your friend - it shouldn't be possible for numbers to be ported (in or out) without the account number and PIN or password (and sometimes additional details as well).  If you have a prepaid account, you should already have a PIN - if you are postpaid, you should have a security measure we'd request when you call in to discuss your account.  If right now there's just the default, you're welcome to add an additional password as well - simply Community-2153 and we're happy to work with you to make sure you're comfortable with the security level.  Thank you, and my sympathies to your friend!  I hope we were able to get his number back for him quickly.

Thank you. I will reach out to your customer service.

Meanwhile, my friend is being helped by T-Mobile. Unfortunately, the hackers took over his account so it is taking some time.

This is kind of what happened to him. To transfer to Fi all they needed was the phone number, T-Mobile account number and name and boom - his number was transferred out in 15 minutes.

I'm so confused!  Even on Fi's page that you linked to, it mentions that the requirements to port are as follows:

  • Name of the account owner
  • Account number from your current carrier—You can find this on your last bill.
  • Account PIN or passcode—Some carriers require this information to verify that you own the number. We’ll use this info for the transfer only. We won’t store or use it for any other purpose.
  • Your social security number (for some carriers)
  • Billing address of the account owner (for some carriers)

I know that when we port out/in, we require not just the account information but the PIN or password and sometimes the other two as well.  I wish I could explain why/how we would release a number/Fi would accept it with less than that - but I'm definitely glad he's in the right hands now!

Click on the specific carrier under that link (T-Mobile).

Wow - thanks for that direction!  I will definitely pass this link on.  I appreciate it!

Two quick questions on this topic.

(1) was the FI link accurate that a pre-payed number can simply be transferred out based on the phone-number (which is equal to the account number) and the customer's name. (i.e., the information published in a phone book).

(2) it is unfathomable to me to think that the FI page is actually accurate, but assuming (1) is correct, can you confirm that the security of this process has been beefed up on tmo's side?

thanks!

Hey folks -- I know it's been almost a year since this was originally posted, but we've made some recent changes to porting security and I wanted to make sure to drop this link here for anyone still interested in this topic. You can add Port Validation -- a feature our Care or T-Force teams will provision and add, as well as a 6 - 15 digit password -- to your account to add an additional layer of security to any port requests. You can find more information here: protect your account from unauthorized porting and you can get this set up by Community-2153​.
