I’m auctioning off out/away (? Non native speaker 😅) my old-ish gaming consoles and this person is asking about a unit’s serial number. Why? I mean, I put up more than ten images of the console from various angles and such… What’s the significance?
Serial numbers are also used by pawn shops for the prevention of buying stolen goods. Only works if you report an item stolen and know its serial number, of course, and this is usually done with bicycles since they’re expensive and the most commonly stolen item there is.
