About
A free tool for checking Nintendo Switch patch status by serial number, running since 2019.
Privacy: we don't collect or store your full serial number. The checker only reads the prefix and first 6 digits you enter, client-side.
Where the data comes from
Every serial range on this site is publicly collected on the GBATemp forums . Thanks to the homebrew community for testing consoles and reporting results over the years — none of this exists without that thread.
