The AR Cards only work with the North American and PAL regions of the game. The QR Codes are North America only. QR Codes for Europe can be found here. None of these will not work with the Japanese version. I will update this post if any new DLC comes out in the future. Keep in mind I am playing the North American version of the game so that is what most stuff will be focused on.
As a note, AR cards can be finicky as their colors are very precise–if you’re having issues, try a different monitor or scanning on your phone.
The 3 Pre-order Frozen costumes are not included as they were a Pre-order gift, the code given is one-use, and you can eventually unlock the outfits to make ingame anyway.
Special Credit to AENIGMA01 for getting this one to work! If you are having trouble with it, try bringing it up on your phone and scanning it there.
