You remember that weird little black-and-white square on the back of your cereal box? Well, Game Freak decided to make it the most important thing in Alola. Honestly, when Pokémon Sun and Moon first dropped, the QR code scanner felt like a gimmick. People thought it was just a way to fill up the Pokedex without actually talking to anyone. But it’s deeper. It’s about Island Scan. It’s about catching things that shouldn't even be in Hawaii—I mean, Alola.
If you're still rocking a 3DS or even dusting off an old save file on your 2DS XL, the Pokemon Sun and Moon QR system is probably the most efficient way to see everything the game has to offer. It’s not just for show. It’s a tool.

The Island Scan Secret
Most players just scan a random code, get 10 points, and move on. That's a mistake. You need 100 points to trigger an Island Scan. Once you hit that 100-point threshold, the game pokes its head out and says, "Hey, there's a rare Pokemon nearby that isn't in the Alolan Pokedex."
This is how you get the starters from Johto, Unova, or Sinnoh. It's how you find a Litwick in a graveyard or a Klink in a canyon. But there's a catch. You only get one hour. One hour to find it, battle it, and catch it. If you mess up, you have to wait until that specific day of the week rolls around again. It’s high stakes for a handheld game.
Why Every Code Works
Here is the thing that people get wrong: you don't need "official" Pokemon codes. You can literally scan the QR code on a bag of chips. You can scan the back of a shampoo bottle. The game doesn't care. It just reads the data string and generates a random Pokemon entry in your Pokedex as a "Seen" encounter.
Think about that. The game is basically procedurally generating "Seen" data based on whatever junk is lying around your house. It's brilliant. It makes the world feel bigger, even if it’s just a clever bit of coding.
Magearna: The Mythical Exception
We have to talk about Magearna. Usually, Mythical Pokemon are a nightmare to get. You had to go to a GameStop in 2017 or hope you didn't miss a Nintendo Network window. Magearna is different. Because of how the Pokemon Sun and Moon QR event was hard-coded, that QR code never expires.
Seriously. You can go find the image on a wiki right now, scan it after you've become the Champion, and head over to the delivery man at Antiquities of the Ages in Hau'oli City. He'll just hand it to you. A Level 50 Mythical, just like that. It's probably the only "legit" way to get a Mythical Pokemon years after the game's prime without resorting to third-party hardware or sketchy trades.
Mastering the Daily Cycle
Island Scan isn't random. It follows a strict calendar. If you’re playing the original Sun and Moon, Monday on Melemele Island gives you Totodile. Tuesday is Deino. But if you're on Ultra Sun or Ultra Moon? The list changes entirely.
It’s easy to get frustrated. You spend all day recharging your scans—you get one scan every two hours, up to a bank of ten—and then you accidentally trigger the scan on the wrong island. Always check your map. If you want a Charmander in Ultra Sun, you better be standing on Route 3 on a Sunday.
The Pokedex Completion Shortcut
Completing a Pokedex is a grind. We all know it. But the QR scanner lets you "register" Pokemon you haven't caught yet. This is huge for the GTS (Global Trade System), or what's left of it. If a Pokemon is "Seen" in your Pokedex, you can search for it specifically.
Without the Pokemon Sun and Moon QR data, you're stuck scrolling through menus or trying to type in names manually, which is a pain on that resistive touchscreen. By scanning a friend's QR code—which every player can generate for their own caught Pokemon—you instantly bridge that gap.
Why the 3DS Camera Matters
Technically, you're limited by the hardware. The 3DS camera isn't exactly a high-definition DSLR. If you're trying to scan codes off a laptop screen, turn your brightness up. Shadows are the enemy here. I’ve spent way too much time tilting my 3DS at awkward angles just to get those 10 points.
It’s worth noting that the "Special QR Codes" are different. These are the ones from the Pokemon movie or specific distributions. They give you 20 points instead of 10. It sounds small, but it cuts your "recharge" time in half. If you're serious about hunting the Island Scan rares, you want a folder of these special codes saved on your phone.
Practical Steps for Your Next Session
If you are hopping back into Alola today, don't just wander around. Use the system.
- Bank your scans: Don't use them as soon as you get them. Wait until you have 100 points (10 scans) ready to go.
- Check the day: Use a real-world calendar. If it's Thursday and you want a Honedge, get your 100 points ready and head to Akala Island.
- Save before you scan: This is the big one. Once you trigger the Island Scan, the timer starts. If you accidentally KO the Pokemon, you're out of luck unless you reload your save.
- Use the Magearna exploit: If you haven't done it, do it. It’s a free Legendary-tier Soul-Heart beast that carries through the elite four.
- Clear your surroundings: If the camera is struggling, find a bright room. The 3DS sensors are old and they need all the light they can get.
The QR system was a bridge between the physical world and the digital one. It's a relic of an era where Nintendo was obsessed with the 3DS's hardware features—AR cards, 3D sliders, and cameras. Even now, it remains the most reliable way to fill those gaps in your Alolan journey. Use the points, catch the Johto starters, and stop ignoring those weird squares. They're your ticket to a much better team.
