How can I find my 3DS serial number without the tags?

I got a 3DS during certain times in 2015, and is currently aging along with me. Now I never realized this, but my younger sister got ahold of it and tore up the tags on both the box and the system. I want to sign up for Club Nintendo and see if my device is still redeemable there, but this is the only Nintendo handheld device I own. What should I do?


Solution 1:

Club Nintendo was discontinued in 2015, so there is currently no way to register the serial number of 3DS consoles.
