You remember the 3DS launch, right? That weird, exciting moment when we realized we could literally "scan" a person into our handhelds. It felt like magic. Honestly, the Mii Maker QR codes system was one of those rare Nintendo ideas that was both incredibly simple and technically brilliant.
Most people think these little black-and-white squares are dead relics of the 2010s. They aren't. Even now, in 2026, those codes are the backbone of massive Mii libraries for games like Miitopia and Tomodachi Life.
If you've ever tried to manually recreate a celebrity Mii by squinting at a YouTube tutorial, you know the pain. One wrong slider adjustment and your "Shaquille O'Neal" looks like a thumb with a goatee. QR codes fixed that. They don't just "link" to a Mii; they are the Mii.

The Magic Inside the Square
Here is what most people get wrong about how these things work. When you scan a QR code in Mii Maker, your console isn't "downloading" anything from a server. That’s why they still work today even though the Nintendo 3DS and Wii U eShops are long gone.
The QR code is actually a tiny, compressed data packet. It contains every single variable of that Mii—the eye spacing, the exact hex code for the favorite color, the nose height, everything. It's binary data living in a physical (or digital) image.
Because the data is local, these codes are immortal. As long as you have a device with a camera and the Mii Maker software, you can summon a Mii from 2011 into 2026 without needing a Wi-Fi connection.
How to Actually Scan Them Now
If you’re dusting off an old 3DS or trying to move characters to newer hardware, the process is slightly different depending on what you’re holding.

On the 3DS and Wii U
This is the "native" way. You open Mii Maker, tap on "QR Code/Image Options," and hit "Scan QR Code."
- Pro Tip: If you're scanning off a phone screen, turn your brightness up. The 3DS cameras are... well, they’re basically potato quality. They need high contrast to see the patterns.
- Once scanned, the Mii just "pops" into your plaza. It’s still satisfying every single time.
The Switch Problem (and Workaround)
Here is the kicker: the Nintendo Switch (and the newer Switch 2) doesn't have a camera that scans QR codes for Miis. It’s annoying. Nintendo moved away from the QR system toward "Access Keys" in games like Miitopia, which do require servers.
But you aren't stuck. If you found a legendary QR code online for a perfect Gandalf or Snoop Dogg, you have to use a "middleman" device.
- Scan the QR code into a 3DS or Wii U.
- Save that Mii to a physical Amiibo.
- Tap that Amiibo to your Switch in the "Create/Edit a Mii" settings.
It’s a bit of a dance, but it's the only way to bridge the gap between the era of "physical" data sharing and the modern cloud-based system.
Where the Best Miis Are Hiding
You shouldn't just scan random codes. There are a few "gold mines" that have survived the death of early 2010s internet culture.
MiiCharacters.com is basically the Library of Alexandria for Miis. It’s categorized by movies, TV, and gaming. If you want a Mii that looks exactly like Peter Griffin or a disturbingly accurate Voldemort, it’s there.
Then there are the "Official" Miis. Nintendo used to release special QR codes for celebrities. We’re talking about official Miis for Zendaya, Shaquille O'Neal, and even Christina Aguilera. These were often distributed for Tomodachi Life promotions. Unlike fan-made ones, these usually have "verified" creator names and specific outfits that are hard to replicate.
Why the "Data is Gold" Philosophy Matters
We live in an era of "everything is a service." When a game server goes down, the content usually vanishes. The Mii Maker QR codes represent a different philosophy: User-Owned Data.
Because a QR code is just a visual representation of a file, you can print it. You can put it on a T-shirt. You can save it as a JPEG on a hard drive and it will be just as functional in thirty years as it is today.
There's a niche community of "Mii Archivists" on Reddit (check out r/MiiQRcodes or r/tomodachilife) who are obsessed with preserving these. They find obscure Japanese promotional codes from 2012 and re-upload them so they aren't lost to bit-rot. It’s a weirdly wholesome corner of the gaming world.
Technical Limits You Should Know
Wait, don't just start scanning everything. There are a few compatibility snags.

- Version Mismatch: A Mii created on a 3DS can usually go "up" to a Wii U or Switch, but you can’t always go "down."
- The "Sharing" Lock: Some creators check a box that says "Sharing: Off." If you scan one of these, you can use the Mii, but you can't edit it. It's like a read-only file.
- Special Miis: Some Miis (the ones with the gold pants) were "Special Miis" distributed by Nintendo at events like E3. You can't usually just "make" a QR code for a Gold Pants Mii and have it keep the gold pants on another system. The "gold" status was often tied to the specific distribution method, not just the facial data.
The Actionable Next Step
If you want to start your own archive, don't just take screenshots of QR codes. Save them as high-quality JPEGs. Open your 3DS right now, go to Mii Maker, and select "Save Mii as QR Code." This saves a clean image to your SD card. Move those files to a cloud drive like Google Drive or Dropbox.
By doing this, you're essentially "backing up" your digital identity. If your 3DS battery ever swells or the hardware fails, those images are your "restore points." You can scan them into any future device that supports the format, keeping your 15-year-old digital avatar alive for the next generation of consoles.
