Nintendo Support: Nintendo Network ID FAQ

A Nintendo Network ID is an ID required to use some of Nintendo’s network services. On Nintendo 3DS family systems, registration is necessary to download free software or demos on Nintendo eShop.

Nintendo Accounts and Nintendo Network IDs are used for different purposes on different systems. For more information, please read What Is the Difference Between a Nintendo Account and Nintendo Network ID?

No, this is not possible. Your Nintendo Network ID is tied to your software and/or additional content you have purchased and downloaded. As the rights of usage for software you have purchased apply only to a single Nintendo 3DS family system, you can only register your Nintendo Network ID on one system.

If you have registered a Nintendo Network ID on a Nintendo 3DS family system, you can transfer this to a new system along with the usage rights to data saved on your SD card, Nintendo DSiWare, your Nintendo eShop user history and balance, any save data from software pre-installed on the system, and Nintendo DS software settings.

However, please note the following restrictions:

• Content cannot be transferred from a New Nintendo 3DS XL system to a Nintendo 2DS, Nintendo 3DS, or Nintendo 3DS XL. Once the NNID is associated to a New Nintendo 3DS XL, it can only be transferred to another New Nintendo 3DS XL.
• If the target system already has a Nintendo Network ID registered on it, you will be unable perform a system transfer.

Pre-installed software on the SD card can be re-downloaded from the Nintendo eShop after a system transfer is performed.
