You remember the hype. Back in 2016, when Pokémon Sun and Moon dropped, everyone was obsessed with the Alola region’s tropical vibes and those weirdly tall Exeggutors. But for the completionists among us, the real game-changer wasn't the Z-Moves or the removal of HMs. It was the scanner. Specifically, the Island Scan. Honestly, the QR codes Pokémon Sun and Moon introduced were a stroke of genius that Game Freak somehow moved away from in later generations, much to the frustration of players who hate trade-evolutions and version exclusives.
It’s a simple system. You open the menu, trigger the QR Scanner, and point your 3DS camera at literally anything with a barcode. A cereal box? Works. A bag of chips? Sure. Your friend's copy of the game? Definitely. Every scan gives you 10 points. Once you hit 100 points, you trigger the "Island Scan," which lets a rare, non-Alolan Pokémon spawn in the wild for exactly one hour. It was the first time we could catch things like Charmander or Honedge in the wild without having to jump through the hoops of the Global Trade System (GTS), which, let's be real, has always been a dumpster fire of people asking for level 100 Legendaries in exchange for a Caterpie.
The Mechanics of the QR Scanner
The math is pretty straightforward. You get ten scans every 20 hours. Each scan refills on a timer, so you can't just spam a thousand codes in one sitting and expect to catch every rare monster in the game. It’s a slow burn. Most people think you need specific Pokémon QR codes to make this work. You don't. You can literally go to Google Images, search for "random QR codes," and scan them. The game doesn't care if it's a link to a local car wash or a nutritional label from a soup can; it just reads the data pattern and assigns a value.
However, if you scan a specific Pokémon’s QR code—the kind you find in the Pokédex of a friend who already caught it—you get a "Seen" entry in your own Dex. This is huge. It doesn't count as "Caught," but it shows you exactly where that Pokémon lives on the map. It's a massive time-saver for those 1% encounter rate spawns like Dhelmise or Sharpedo.
Finding the Rare Stuff with Island Scan
Island Scan is where the real magic happens. Since the Alola Pokédex is actually pretty limited, the developers used the Island Scan feature to "import" classic Pokémon from Kanto, Johto, Hoenn, and Sinnoh. But here is the catch: the Pokémon you find depends entirely on which island you are currently standing on and what day of the week it is.
If you’re on Melemele Island on a Friday, you're going to find a Chikorita. If you wait until Sunday on that same island, it's a Cyndaquil. It created this weird, localized meta-game where players were actually checking their calendars before turning on their handhelds. It felt organic. It felt like these Pokémon were actually migrating through the region, only appearing at certain times.

Why the Magearna QR Code is Different
We have to talk about Magearna. This is the one instance where the QR codes Pokémon Sun and Moon uses aren't random. Magearna was the first "Mythical" Pokémon distributed via a permanent QR code rather than a limited-time Mystery Gift event that expires after two weeks. If you’ve finished the main story and become the Champion, you can scan the special Magearna code (which is still easily found on the official Pokémon website or various archives) and pick up your Steel/Fairy legendary at the Antiquities of the Ages shop in Hau'oli City.
This was a massive shift in how Nintendo handled distributions. Usually, if you bought the game a year late, you were just out of luck for Mythicals. With this code, the content is baked into the software. It’s a permanent fixture. It makes you wonder why they didn't do this for Marshadow or Zeraora, but hey, at least we got one.
The Special Case of "Partner Cap" Pikachu
If you’re playing the "Ultra" versions—Pokémon Ultra Sun or Ultra Moon—there’s a specific QR code associated with the I Choose You! movie. Scanning this gives you a Pikachu wearing Ash’s movie cap. Unlike regular Pikachu, this one can use the "10,000,000 Volt Thunderbolt" Z-Move if you have the Pikashunium Z crystal. It’s a niche bit of fan service, but for collectors, it’s a mandatory scan. You find it at Pikachu Valley on Akala Island. The delivery man just stands there waiting for you.
Maximizing Your Scan Points
A lot of players get frustrated because they hit the "Limit Reached" message constantly. The trick is understanding the "Special QR Codes." While a standard code gives you 10 points, certain promotional codes—like those found on physical Pokémon TCG cards or special Japanese movie pamphlets—give you 20 points. This cuts your grind in half.
The community has basically archived every single one of these. You can find "Master Sheets" online that contain every single Alolan Pokédex entry in QR format. If you’re a new player in 2026, or just revisiting the 3DS for nostalgia, these sheets are your best friend. You can literally sit in front of your computer monitor, point your 3DS at the screen, and "batch scan" your way to a full "Seen" Pokédex in about an hour.

Things the Game Doesn't Tell You
- Shinies: You can't get a Shiny Pokémon just by scanning a Shiny QR code. It just adds the Shiny sprite to your Pokédex.
- Egg Moves: Pokémon caught via Island Scan often come with a "special" move they wouldn't normally have at that level. For example, catching a Litwick on Akala Island might net you a Pokémon with an egg move you'd otherwise have to spend hours breeding for.
- Hidden Abilities: Unfortunately, Island Scan Pokémon never have their Hidden Ability. You're stuck with their standard ones. If you want that Regenerator or Intimidate, you’ll still have to do the SOS Chaining method.
- Level Scaling: The levels of Island Scan Pokémon scale based on which island you’re on. Melemele spawns are low-level (around level 10), while Poni Island spawns can be in the 40s or 50s.
Is it Cheating?
Some purists argue that using an online database of QR codes Pokémon Sun and Moon ruins the "exploration" aspect of the game. I disagree. The Alola games are notorious for their long tutorials and "hand-holding." The QR system is the one part of the game that actually respects your time. It gives you a roadmap.
If I want to find a Bagon, and the game tells me it has a 1% spawn rate in a specific patch of grass on Route 3, having that confirmed in my Pokédex via a scan doesn't make the catch any easier. I still have to run around in circles for forty minutes hoping the RNG gods smile upon me. It just removes the guesswork.
The Evolution of the Mechanic
Looking back from the perspective of the Switch era, the QR scanner was a bit of an anomaly. Pokémon Sword and Shield moved away from it entirely, opting for the Wild Area and Max Raid Dens. While Raids are fun, they lack the "collect them all" tactile feel of scanning physical objects in the real world to unlock digital rewards. It bridged the gap between the physical TCG and the digital RPG in a way that felt like a precursor to Pokémon GO.
How to Get Started Right Now
If you're booting up your save file and want to use this to its full potential, here is your path forward. Don't just scan randomly.
First, finish the first trial. You can't use the scanner effectively until you've at least cleared the Verdant Cavern. Once that's done, go find a high-quality "Global Link" QR code gallery online. These galleries usually have all 400+ Pokémon laid out in a grid. Start scanning the ones you're missing.

Prioritize the Island Scan Pokémon that are actually useful for a playthrough. For instance, on Akala Island (the second island), you can find Honedge on Wednesdays. Aegislash is an absolute beast in the Alola trials because of its typing. On Ula'ula Island, you can snag a Swinub on Mondays, which eventually gives you Mamoswine—a total dragon-slayer for the late-game fights.
The Checklist for Success
- Check the Day: Always verify your 3DS system clock. If it's Tuesday and you want a Thursday spawn, you'll have to wait or risk "time-locking" your game by changing the clock (which freezes daily events for 24 hours).
- Clear the Area: Make sure you're actually on the right island before you hit the 100-point mark. If you trigger the scan on Melemele when you meant to be on Poni, you've wasted your 100 points.
- Prepare for the Catch: Island Scan Pokémon only stay for one hour, and you only get one encounter. If you accidentally faint it or run away, that's it. It's gone until the same day next week. Bring a Pokémon with False Swipe and a status move like Thunder Wave or Spore.
- Save Your Game: Save before you trigger the Island Scan. If you mess up the catch, you can just soft-reset and try the encounter again within that one-hour window.
The QR system in Alola isn't just a gimmick; it's the backbone of a stress-free Pokédex completion. It turns the world around you into a giant treasure chest. Even though the 3DS era is technically "behind us," these games hold up remarkably well, and the QR codes are a big reason why. It makes the world feel bigger than just the code on the cartridge.
Go find that Magearna code. It's sitting out there on the internet, waiting for you to claim a legendary that most people forgot was even available. Use the scanner to fill those annoying holes in your collection. It’s the most efficient way to play, and honestly, it’s just fun to see what a random barcode on a box of crackers will give you.
Grab your 3DS, make sure the lens is clean, and start scanning. The Island Scan list is your roadmap to a team that isn't just the same five Alolan Pokémon everyone else uses. It’s how you get a Samurott in Hawaii, and that’s a vibe you just shouldn't pass up.
Actionable Next Steps
- Download or Bookmark a QR Gallery: Search for the "Complete Alola QR Code" images on Reddit or project-specific sites to have them ready on your phone or PC.
- Sync Your Calendar: Determine which Island Scan Pokémon you need (like Deino, Axew, or the Johto Starters) and set a reminder on your phone for that specific day of the week.
- Claim Magearna: If you haven't already, find the official Magearna QR code and scan it after becoming Champion to add a Mythical to your roster instantly.
- Stock Up on Quick Balls: Since you only get one shot at Island Scan encounters, using a Quick Ball on the first turn is the most efficient way to ensure you don't accidentally faint a rare spawn.
