SOLVED! PayPal Asking for "Full Account Number"

When changing important information in PayPal, at times,it asks you for the "Full Account Number". This is a security measure, but really to the extreme that it's actually misleading you. After entering what you think the "Full" Account Number, it reported an error saying like "...information incomplete or something is missing..."

In fact, when entering the "Full Account Number", just skip the bank code and the branch code, simply enter the rest of the digits will do. It will be like a 9-digit number.

Give it a try... PayPal ... what's happening to you...
