What is a Nintendo Network ID (NNID)?
A Nintendo Network ID is a unique identifier made up of 6 to 16 characters that allows you to access Nintendo Network services, such as Miiverse and Nintendo eShop, on Wii U and Nintendo 3DS family systems. On Wii U, players can use Nintendo Network IDs to register each other as friends on the friend list.
By registering a Nintendo Network ID to your Wii U or Nintendo 3DS, you can enjoy a wide range of network services. You can post about your game experiences on Miiverse, our unique network communication service, get access to great downloadable content from Nintendo eShop, and much more!
As of 10th December 2013, it is also possible to register a Nintendo Network ID on Nintendo 3DS family systems.
If you have registered a Nintendo Network ID on your Wii U, you can register the same Nintendo Network ID on Nintendo 3DS family systems. Using the same Nintendo Network ID on both systems will allow you to use your Nintendo eShop funds on both your Nintendo 3DS family system and a Wii U console.
For more information, please visit our Nintendo Network ID Support section.
When creating an NNID, the user must provide their date of birth, gender, country, region, time zone and email address.
