I have searched and searched for information about this topic. I have had no luck. I am trying to add inventory to the FBA under manage inventory. These are listings we already have listed on Amazon. Can anyone point me in the direction I need in order to get these listings under my “fba inventory”? I am also looking to buy the UPC labels from Amazon. Thanks in advance.
You cannot buy UPC labels from Amazon. UPCs are issues by GS1. Getting them from any other source risks them not working as they will not be registered to your brand/product.
I would suggest going through seller university and then the help files as there is plenty of information on how to send inventory to FBA.
