Get your QR Scanner codes here!
QR Scanner is a feature in Pokemon Sun and Moon that allows you to scan a QR code. Once scanned, it gives you a Pokedex entry for a Pokemon from another region. Every 10 QR codes, you get the ability to Island Scan: a Pokemon is revealed on the island you are on and you have 1 hour to find and catch it. It's considered a wild pokemon so you have to search the tall grass. It will tell you what route it is on. You only have 1 chance to catch it, so don't let it faint! You can find information on which pokemon appears on this link.
This generator can provide you the QR codes to scan in order to enable the Island Scan ability. You can generate as many QR codes as you want by clicking the "regenerate" button, however, you can only scan 10 per 10 hours into your game.
