You are unable to redeem a download code, and you receive the error code 2813-6561.
In most cases, this error indicates the Nintendo eShop card or download code was entered incorrectly, or was intended for a different region's Nintendo eShop.
What to Do:
Attempt to enter the download code again, ensuring you have entered the code exactly as it appears.
If the error persists, than it is likely the code may be intended for a different region. You can take the following actions to ensure the download code is intended for Australia or New Zealand.
If the code was included with a physical game purchase, check packaging for an ESRB or PEGI rating. Games with an ESRB or PEGI rating are typically intended for sale in the Americas or Europe.
Check the retailer you purchased the download code and ensure they are located within Australia or New Zealand.
Contact the retailer and ask which region the download code is intended for.
Situation Not Resolved:
If the issue persists, it is possible that there is an error with the download code.
