Click on the Address Book to the right side of the screen. Your address book should open to the first page. You should see your Wii's console number displayed here as a 16 digit number (e.g. 9999 9999 9999 9999).

Alternatively, you can click on the small arrow to the left side of the screen to flip to the cover page.


Write down this number. Give this number to your friend.;

This step is optional.
