Not true. Commingled inventory does not get a unique barcode for each seller, it just uses the default UPC. So there's no way for Amazon to even tell who sent it. This is why many sellers avoid commingled inventory altogether, because you end up selling something that's counterfeit and getting a hit to your account when you didn't even send it to Amazon. Over time, I think this probably means that commingled is really becoming a market for lemons, with counterfeits making up a higher and higher percentage. Source: very casual FBA seller

Your house/apartment doesn't have a UPC on it either, but nobody's confusing it with mine. Location matters. Amazon keeps different sellers inventory in different bins, which are tracked. I agree that some sellers are avoiding it, but I know several big sellers that are all commingled. Most of my business was merchant fulfilled, but I still sold over six figures worth FBA last year. Never had an issue from commingled.

  Commingling is an odd term to use for items kept in separate bins where there is accurate tracking as to which bin it came from. Commingled and separate? Heh. If it's very accurate, and keeps things separated, you have to wonder why Amazon offers "Stickerless Commingling" and "Stickered Commingling". What does the sticker add if the bin system is working so well?

    https://www.amazon.com/gp/help/customer/display.html?nodeId=200243180 https://www.amazon.com/gp/help/customer/display.html?nodeId=... That may be why they stopped calling the option commingled. They still use the word, but the option is just called "manufacturer barcode". It used to be called stickerless commingled inventory. There's no stickered commingled option. There's stickerless commingled and stickered separate inventory. One reason amazon keeps the stickered option is because some people might want to be able to get the exact inventory they send in back. And some items don't make sense to be commingled, like used items, items with experation dates, etc.

      Hmm. They also don't allow commingled for DVD, Blueray, etc. That sort of feels like a nod to the sticker tracking being more accurate, since those are highly lucrative to counterfeit. Maybe for returns though?

        I think they won't accept it for any category that requires approval.
