I need my FULL account number.  I tried what Sheogunsola recommended and added the three numbers listed before my account number on my bill but its still has issues.  I’m trying to convert from T-mobile to Mint and I need my full account number.  Is there anyone who can assist?  Thanks

 

Sign into your MyTmobile account and download a bill. Account number is on it if you have a post paid plan.
