If you mean a Friend Code, just go to the smiley face icon on the home screen and it tells you there. If you mean a QR code, while on the Mii Maker, go to image options (or something like that) and do save mii as QR code. hope this helps
A 3DS is Nintendo's latest handheld device (aside from the 3DS XL, a bigger 3DS) that boasts several capabilities over its predecessor, the DSi. These include the ability to make Miis, a redegisned home menu where you can change the dimensions and create menus, Streetpass, Spotpass, the Nintendo eShop, AR Card readers, QR code scanners, and of course, 3D.
To get a QR code, you can use a free online QR code generator like Adobe Express, The QR Code Generator, or ME-QR. These tools allow you to enter information like a website URL, text, or other data, and then generate a unique QR code that can be scanned.
If your 3DS camera isn't functioning in specific apps like the camera, AR Games, or QR code scanner but works elsewhere, it may be a software glitch. Try restarting your 3DS to see if that resolves the issue. If the problem persists, consider updating your system software or performing a factory reset after backing up your data. If none of these steps work, you may need to contact Nintendo support for further assistance.

To create a QR code that links to a website using spray paint, you can first generate the QR code online and then print it out. Next, use a stencil to spray paint the QR code onto a surface. Make sure the paint doesn't smudge the code, and test it with a QR code reader to ensure it works properly.
You need a QR code to unlock Metal Mario (like all of the color yoshis). So far Nintendo has not shown the USA code. But the Europe,Astraia,and Japan codes(if you are from one of thoses place just Google it). If you are from USA wait untill Nintendo releases the QR code. They most likely will in a couple of days.
