D2B el. D2C, vilket har jag?

Tjena!
Har precis köpt en amerikansk nintendo wii och serienummret på den verkar inte vara i samma nummerföljd som dom europeiska. Är det någon som vet vilka serienummer som gäller för amerikanska versioner eller känner till någon sida där man kan hitta sån information? Måste jag skruva upp den för att kolla upp det?
