Redeeming a Switch eShop gift card adds funds to your account for buying games. Open the Nintendo eShop on your Switch and select your user profile. Scroll down and select 'Enter Code'—you’ll see a keyboard on the screen. Scratch off the silver panel on the back of the gift card to reveal the 16-digit code. Enter the code exactly as it appears, including hyphens, then select 'OK'. The funds will be added to your Nintendo Account immediately—you’ll see a confirmation message with the new balance. To use the funds, browse the eShop, select a game, and choose 'Proceed to Purchase'—the cost will be deducted from your balance. Gift cards are available in various denominations (e.g., $10, $20, $50) and can be bought online (Amazon, Nintendo.com) or in stores (Walmart, Target). Funds never expire, so you can save them for future purchases.
