Issues Registering Razer Blackshark V2 x

I’ve recently recieved a Razor Blacksark V2 X from my aunt, while attempting to activate 7.1 i’ve been requested to provide a activation code, i searched it everywhere i could but could not find one. i then attempted to use Razer ID to register the product however it required shipping information, my aunt bought it at a store in person so i don’t have shipping information.
