Please check to see if one of the following issues applies:
The date of birth listed for the Nintendo Network ID must match the date of birth for the Nintendo Account you're trying to link to.
You cannot link a Nintendo Network ID if the country of residence setting does not match that of the Nintendo Account you're trying to link to.
You cannot link a Nintendo Network ID if the NNID is set to restrict off-device usage. Access your NNID settings on a Wii U or Nintendo 3DS family system, and verify that the NNID is set to allow "Usage from PCs and Other Devices".
If you do not remember your NNID sign in information, use the "Forgot your NNID?" or "Forgot your password?" links on the screen for assistance.
