This number is unique to each and every Gamecube and Wii ever produced. It would be very interesting if we found out what the bits in it are. For example, it might show manufacture date (year, week, month, day), and other cool things like where it was produced, etc.
Please post them here with the relevant info, such as:
Console purchase date
First few numbers of the serial if it's a Wii
Full serial if it's a GC
Console Region
Console Color
If you have many consoles, run it on all of them - the more data the better
If you want to remain private about the info, please submit them to me via PM and I will not make them public.
Should be interesting to see if we can extract some useful data from this number
