How to redeem

Select “Nintendo eShop” on the HOME Menu to launch Nintendo eShop.
Select the account you want to use.
Select “Redeem Code” on the left side of the screen.
Enter the 16-character download code.
Some retailer cards for Nintendo Switch software will include both a Control Number and a Download Code. Make sure that you are entering the Download Code (usually begins with a B, no hyphens in the number) and not the Control Number (usually begins with an S, has hyphens).
Any letters and symbols not used with prepaid codes (i.e. O, I, Z, commas, hyphens, etc.) will be disabled from the on-screen keyboard.
Select “Confirm”. The software will begin downloading once the code is confirmed.
The software icon will appear on the HOME Menu, with a download status bar. The status bar will disappear once the game download is complete.
