Interested in buying a few Switch Lite systems in September. We have Nintendo Network IDs that were merged with Nintendo Accounts. The question is when you first set up a Switch does it auto generate the 12 digit code or is the 12 digit code generated after you link a Nintendo Account? Curious to know if the Switch friend code is locked to the Nintendo Account or the system itself. You have multiple Switch systems and you link your Nintendo Account to them does the Switch friend code remain the same for all devices?
