Things You'll Need
Instructions
Look for the serial number. Every Nintendo Wii has a serial number on the side of the console beneath the UPC (Universal Product Code) and next to the console's fan.
Write down the serial number. The number will begin with LAH and end with an eight-digit number. Your Nintendo Wii serial number cannot be below 10000000.
Determine your version. If your LAH number is between 10000000 and 10160000, your Wii is a first-generation model, or V1. If your LAH number is between 10160000 and 10875000, your Wii is a second-generation model, or V2. If your LAH number is 10875000 or higher, your Wii is a third-generation model, or V3.
