Things You'll Need
Instructions
Turn off your Nintendo Wii. You don't want to accidentally unplug the Wii while you are locating its serial number.
Find your serial number on the bottom of your console. It is the 12-digit number located directly underneath the bar code.
Dial 1-800-255-3700 (as of August 2010). Select the option to speak with a customer service representative.
Provide the representative with your serial number. Inform the rep that you would like to know the manufacturing date of your Wii. The Nintendo rep can provide that information for you.
