We put this guide together after seeing fake Switch games show up in the resale market. One of the first cases we noticed was a real Switch cartridge with a label that had been swapped, so the label didn’t match the serial number markings. The game looked genuine at first, but the differences only became clear when we compared several copies side by side. That experience made us start documenting the specific checks we now use whenever we get a Switch game.
Here are the main signs to help you tell real Nintendo Switch games from fake ones.
Key Points to Spot Fake Nintendo Switch Games
- Check the serial numbers and barcodes on both the front and back of the cartridge.
- They should be the same. If they are different, the game might be fake. Letters and real Nintendo Switch cartridges have specific markings.
- Be careful with display cartridges. Real games should not have a "KYOTO" label.
- Try the bitter taste test. Licking the cartridge can help you verify whether it is real.

Step 1: Examine Serial Numbers and Barcodes on Genuine Switch Games
- On the front label, you’ll see writing on the bottom of the label like: LA-H-AXB8A-USA. This is the game's model number.
- On the back of the cartridge, in white lettering, there will be serial numbers. The third group of numbers [AXB8A] must be included in the serial number on the back of the cartridge. This is a key point: the front & back numbers must match.
- As GameStop has been hit hard by people trading in games with counterfeit labels. Scammers are buying cheap games and relabeling them to make them appear more valuable.

Step 2: Examine Imprinted Numbers and Letters on Authentic Cartridges
- Just above the serial number on the back of the cartridge. Each genuine Nintendo Switch cartridge will have the Nintendo HAC-008 & the letters CC imprinted on it.
- Fake Nintendo Switch games may lack or have altered serial numbers and barcodes. Inspect errors or signs of tampering, such as smudged ink or mismatched fonts. It's important to remember that most counterfeit games are inexpensive and poorly made.

Step 3: Beware of Display Cartridges
- What is happening here is that someone is selling these display cartridges as if they are real games. This could be intentional or accidental. They appear to be genuine game cartridges, but the "KYOTO" label on the back is a key indicator that the game is counterfeit.
- When examining this Breath of the Wild Cartridge. (below) – You’ll notice the model #number on the front bottom of the game. [LA-H-AAAAA-JPG]
- On the back of the cartridge, the model number needs to be identical to the one on the front. On the back cartridge, the model number starts with [KYOTO] rather than [AAAAA]. This is also a very similar method you can use on How to tell if a DS Game is fake or real.

Step 4: Licking the Cartridge
- Yes, you read that correctly, lick the cartridge and see if it tastes bitter.
A bittering agent (Denatonium Benzoate) has also been applied to the Nintendo Switch game cartridges. This bittering agent is non-toxic. Yes, it sounds gross, but at least you’ll know.
