Hello, I have recently purchased my first GoCash Game Card to purchase items in the Item Shop. I went to refill eCoin and then scratched the back of my game card. However, I am confused because the page asks for a 10 to 15 digit PIN number. My game card instead has four sections of four digits, making up a total of 16 digits. What should I do? Thanks for the help.

Sorry for an awkward first post and sorry if the issue is pretty simple.
