3DS users won’t be able to change regions and use multiple currencies after registering a NNID

3DS users should keep something in mind about the system’s upcoming firmware update. According to an official page on Nintendo of Europe’s site, owners will be unable to change regions and use multiple currencies after they’ve registered a Nintendo Network ID.

The official notice reads:

After registering a Nintendo Network ID, you will be unable to change regions and use multiple currencies – for instance, pounds and euros – in Nintendo eShop. The funds in the currency that corresponds to the country setting of your Nintendo Network ID will remain, and any funds in other currencies will be deleted and no longer usable. Please make sure to use up any other currencies before registering a Nintendo Network ID to your Nintendo 3DS system.
