The 18 digit code inside the box is a serial code for the square-enix member site.

it's like a proof of purchase that will list you have bought the game.

So where is my code to register my copy?

You should have another slip of paper with "Registration code" noted on it, or something similar.

I don't have a standard version so I'm not sure how they included the code for you.

It could be a sticker or field inside a manual.
