Those who live in South America have access to a website where download codes for games can be purchased. These codes can then be redeemed on the South American eShop. The only problem with this is the inability to earn Gold Points on My Nintendo for these codes. The good news is that there’s a workaround.
All a user has to do is take the download codes and redeem them on the North American eShop. Doing so will let the user earn Gold Points, which can be used on an America/Canadian Nintendo Account. This works due to South American eShop codes working on the North American eShop.
Fortunately, we have learned that download codes purchased in South America could be redeemed on the North American eShop. This means you get to earn Gold Points off your downloads and have everything consolidated on a single American/Canadian Nintendo Account.
