Yep, that's it! I thought that when I made my ones, I could work to make unique numbers on each of those. The only thing is, I don't know if the letters have any meaning. I can always put in random letters and numbers like I do with the date code and INV-REF (which I don't think is related to the codes at the top of the cards) if necessary, but I'm still curious as to what it might mean.
