Amazon systems are barcode-driven. Each product you send to a fulfilment centre requires a barcode so that it can be tracked throughout the fulfilment process.
Label Products is the third step in the six-step shipment creation process:
Products that do not qualify for Stickerless, Commingled Inventory must have FBA labels in order to be received at Amazon's fulfilment centres. By selecting the Labelling required filter on the Label Products page, you can view the products in your plan that require labels.
For products that require Amazon barcodes, you must apply a barcode to each unit of the product and cover any existing barcodes. When applying a barcode label, cover the original manufacturer barcode (UPC, EAN, ISBN). Failure to cover these barcodes can cause errors in receiving and may result in misplaced inventory. Do not cover any serial number barcodes which uniquely identify the item (for example, IMEI barcodes on mobile phone packaging). If the proximity of multiple barcodes prevents you from applying a label without obscuring the serial number barcode, then place the item in a transparent poly bag and apply the Amazon barcode to the outside of the bag. Serial numbers must also be clearly visible as Amazon may record them. Obscured serial number barcodes may result in unplanned prep fees or classifying the item as unsellable.
You have several options for printing product labels:
If you have selected Amazon in the Who prepares? column of the Prepare Products page for a given product, then you will be required to use the FBA Label Service, and "Amazon" will be automatically applied to the Who labels? column. If you are prepping a product yourself, then you may still use Amazon Labelling by selecting "Amazon" in the Who labels? column on the Label Products page. Labelling fees will apply to all units that Amazon labels.
Amazon can only label products that have an product identifier (UPC, EAN or JAN) on the product itself. Refer to FBA Label Service and FBA Prep Service for additional information and fees.
