About this Site
How does it work?
Did you know that it's possible to determine the age of your Nintendo Switch by its serial number?
Our website allows you to check if your Switch is a patched unit by simply entering the first 10 characters of your serial number (including the prefix).
Rest assured that we do not collect your full serial number on our website.
If you've found this website useful, consider making a small donation so that I am covered with hosting/domain expenses.
Your support is greatly appreciated!
All of the serial numbers data used on our website is publicly available on the GBATemp forums .
