Account number

You need to call for your prepaid account number, it is not available online.

I learned today that if you login via www.att.com with your prepaid credentials, you arrive at a page that shows what appears to be a valid account number.  Then if you continue on to what you see if you login via paygoonline, it goes away.  I need to verify whether this is correct or not.  

Note, I have a different email address for my postpaid iPad account and my prepaid phone account.
