Help! I lost my 3DS pin#! Somebody please tell me how I can still register my 3DS without the pin. Thanks!
You can still register the serial number to get the 90 day warranty extension. If you want the coins, however, you will need that PIN#. If you really lost it, maybe Nintendo can help you out. You can call them at 1-800-255-3700.
I know this is an old issue, but I had the same problem but it was for a game.
Nintendo just had me mail in the UPC code on the box and they added my coins manually. Did you get your problem solved yet?
