FBA product barcode requirements
FBA uses barcodes to identify and track inventory throughout the fulfillment process. Each item you send to an Amazon fulfillment center requires a barcode.
There are three kinds of barcodes for identifying products:
Manufacturer barcodes (eligible barcodes include GCID, UPC, EAN, JAN, or ISBN)
Amazon barcodes (such as FNSKU)
(Brand owner only) Some products may require an additional Transparency authenticity code to help prevent counterfeit
Note: As of April 17, 2018, GCIDs can no longer be used in place of a UPC, EAN, JAN, or ISBN to create ASINs. If your brand has been approved for the Brand Registry program and you don’t have UPCs, EANs, JANs, or ISBNs for your products, apply for GTIN exemption.
Amazon will always use the manufacturer barcode to track inventory throughout the fulfillment process, unless you change your barcode setting. If more than one seller has inventory with the same manufacturer barcode, Amazon fulfills orders with inventory that’s closest to the customer. We do this to facilitate faster delivery.
If you do not have an eligible barcode for your product, an Amazon barcode can be used in place of the manufacturer barcode.
For more information, see Using the manufacturer barcode to track inventory.
Amazon barcodes must be applied to all products that are not tracked using manufacturer barcodes. This category is comprised of:
Products with an expiration date
Topical products such as skin creams, shampoos, and cosmetics
Products that are prepped so that the barcode cannot be scanned
You can print Amazon barcodes and apply them to your products yourself, or Amazon can print and apply them for a per-item fee. For more information, see Use an Amazon barcode to track inventory and FBA Label Service.
Transparency authenticity codes
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 be covered by any other label, nor cover any other label. To learn more and see a sample sticker, see the Transparency page.
