An error occurs when you try to redeem a download code that was issued as a My Nintendo Reward (Game or DLC).
Reward codes used to order My Nintendo Store rewards are not download codes.
For download codes purchased through a retailer (NOT as a My Nintendo reward), click here.
What to Do:
Make sure the country setting is correct on your Nintendo Switch console.
A download code for a Australia and New Zealand game can only be redeemed on a Australian or New Zealand system.
If you are attempting to use a download code or system from a different region (a North American download code with a Australian system, for example), the code will not work.
Situation Not Resolved:
If the above steps do not resolve your problem, we will need to research your issue further. Please contact our Customer Support.
