>Additionally, Amazon is offering an optional product serialization service for companies that would have them put a unique, Amazon serial code on their products during manufacturing that will then allow Amazon to scan and confirm that a given products is authentic before it ever leaves a warehouse.

If the manufacturer opts in to this serialization, as a customer, co-mingling wouldn't be an issue. If a co-mingled counterfeit item gets picked, it wouldn't leave the warehouse. The Amazon worker would then put the counterfeit item to the side and find a genuine one.

For the manufacturer/Amazon, it would still be difficult to find who shipped the fake item.

Amazon should be doing this to ALL of their inventory, marking where particular item came from for the purpose of following up post fake discovery.

Instead Amazon gets to point finger and blame bad bad manufacturers not bothering to do Amazons job.

But this is only for a select few companies , isn't it?

... because it's impossible to just copy the serial code, too?

Maybe it's a use-once uuid-like code like things like gift cards use?
