There are two ways to redeem a Nintendo eShop code. On Nintendo Switch: open the Nintendo eShop from the home screen, select your account, scroll down the left sidebar and select Enter Code, type in your 16-character code (format: XXXX-XXXX-XXXX-XXXX) and select OK to confirm. On a web browser (PC, phone, or tablet): go to ec.nintendo.com/redeem, sign into your Nintendo Account, enter your 16-character code, click Next, re-enter your password and click Redeem. Note: the Nintendo Switch Online mobile app does not support code redemption — use a web browser instead. Nintendo codes are region locked and must match the country setting of your Nintendo Account. The letters I, O, and Z are never used in Nintendo codes — if you see what looks like one it is actually a number (1, 0, or 2).
