How to Check Your Wii Serial Number
- 1). Unplug the audio/video cable and the power cable from the back of your Wii. Set the Wii console on a flat surface with the CD drive facing you.
- 2). Turn the Wii console around so you are looking at the back of it. Notice the bar code on the center of the back of the console.
- 3). Look directly underneath the bar code. You should see the words "Serial No:" followed by 12 letters and/or numbers. Write down the sequence of letters and numbers. This is your Wii's serial number.
