Here's how to flesh out your Alolan Pokédex

Pokémon Sun and Moon QR codes allow you to scan codes of (practically) every Alolan Pokémon and add them to your regional Alolan Pokédex. Not only is it a useful way of cataloguing creatures so you can later locate them in the wild, the system also allows you to catch an additional 28 non-Alolan Pokémon that you can't get anywhere else - until Pokémon Bank support from previous generations is introduced, that is. To scan a QR code, open the menu, head to the second page and select the 'QR Scanner' option. The camera will activate, and place the desired QR code in front of it and snap.
