Nintendo Support: What Is a Nintendo Network ID?

The Nintendo Network is the service that provides games and content via the Internet (Nintendo eShop, etc). It gives access to a wide range of network services, such as playing games with people from around the world, downloading software and content, and exchanging images and messages.
