Nintendo has confirmed the exact closure dates for its 3DS and Wii U eShops.
Per updated support pages, Nintendo will be permanently closing its 3DS and Wii U eShops for users in the West on March 27, 2023. That will be followed by the closure of their Japanese counterparts, which will occur a day after on March 28, 2023.
3DS and Wii U eShop purchases will no longer be possible following these dates, but as Nintendo explains, existing balances can still be used to purchase content before the closure date in March.
Users who link their Nintendo Network ID wallet (used with Wii U and the Nintendo 3DS family of systems) with their Nintendo Account wallet (used with the Nintendo Switch family of systems) can use the shared balance to purchase content on any of these systems until March 27, 2023. After that, the balance can only be used to purchase content for the Nintendo Switch family of systems.
Some of the 3DS and Wii U eShops’s related services have already ceased to function. These include the ability to “use a credit card to add funds to an account in Nintendo eShop on Wii U or the Nintendo 3DS family of systems,” which stopped being possible on May 23, 2022.
And starting on August 29, 2022, users will no longer be able to “use a Nintendo eShop Card to add funds to an account in Nintendo eShop on Wii U or the Nintendo 3DS family of systems,” although download codes can continue to be redeemed until March 27, 2023.
Nintendo has clarified that no changes are planned for the Nintendo Switch eShop, and that users will be able to “redownload games and DLC, receive software updates, and enjoy online play on Wii U and the Nintendo 3DS family of systems” even after March 27, 2023.
