This database is to correlate Wii U serial numbers to firmware versions.
The serial number is found on the bottom of the Wii U box and on the bottom of the Wii U system. On the box, it has it's own designated barcode with "PRODUCT SERIAL NUMBER" printed below it. The serial number is two letters followed by nine numbers. Please only post the two letters and first FIVE numbers of the serial number with four X's following.
The firmware that your Wii U is on is found in the Settings menu. Please only log the firmware that your Wii U came on, not what you're on after updating via internet or game disc. Please do not post if you are not 100% certain, as this could throw off all of the data.
Enter your Wii U's serial number and starting firmware version under the correct region in which it belongs. Your region can be found in the Settings menu directly after the firmware version number.
With many entries, it may be possible to find a cutoff point for where each firmware started being loaded onto the systems.

If you're trying to find a match in the table for a serial number you have found, please expect to do some deductive reasoning. If your serial number is a lower number than one in the table, it can be implied that your system has the same or lower firmware.
*If anyone knows how and wants to spruce anything else up, please do. I tried and couldn't figure some of the stuff out lol.*
