Pepsi max website code error.

Hi, I recently(30minutes) purchased 5 bottles of Pepsi Max with Fifa 25 promotion. A problem occurred when inputting the codes where it tells me "Invalid code format, code must be 8 characters long and can contain only characters: 0123456789ACEFGHJLMNPRTWXY. Please try again.". The problem is that in Sweden where I am, it's supposed to be 12 characters. Please help!
