Unrecognized Serial Number | Razer Insider
Skip to main content

Unrecognized Serial Number; when i try to register my mouse and I add S/N or not; whenever I change the “1” or the letter i in caps or not, same as the 0 and the letter o in caps or not, always says:

Please double-check similar characters such as:

"I" and "1"

"O" and "0"

If you have Synapse 4 (beta) you can actually copy the serial number and just paste it to register with RazerID.
