Fulfilment by Amazon uses barcodes to identify and track inventory throughout the fulfilment process. Each item that you send to an Amazon fulfilment centre requires a barcode.
There are three kinds of barcodes for identifying products:
By default, Amazon will use the manufacturer barcode to track eligible inventory throughout the fulfilment process, unless you change your barcode setting. When more than one seller has inventory with the same manufacturer barcode, Amazon may fulfil orders with the inventory that is closest to the customer, for faster delivery. Using the manufacturer barcode means that you will not need to apply an additional Amazon barcode sticker to each item.
To send to Amazon with the manufacturer barcode, go to Using FBA virtual tracking.
If your product is not eligible to track with only a manufacturer barcode, an Amazon barcode will be required in place of the manufacturer barcode. Unless you are the brand owner and have enrolled the ASINs to Amazon Brand Registry, you may use the manufacturer barcode for that brand while non-brand-registered sellers are required to apply Amazon barcodes.
Amazon barcodes must be applied to all products that are not tracked using the manufacturer barcode. These products include the following:
You can print Amazon barcodes and apply them to your products yourself, or you can have Amazon print and apply them for a per-item fee. For more information, go to Use an Amazon barcode to track inventory and FBA Label Service.
Transparency codes are item-level authentication stickers that help protect brand owners and customers from counterfeit. Transparency codes are accompanied by a Transparency “T” logo and must not cover or be covered by any other label. To learn more and see a sample sticker, go to Transparency.
