Amazon systems are barcode-driven. Each unit you send to a fulfillment center requires a barcode so that it can be tracked throughout the fulfillment process.
Products that do not use a manufacturer barcode for tracking require an Amazon barcode. You can print Amazon barcodes from within your seller account and apply the barcodes yourself.
If you do not want to apply the barcodes yourself, you can sign up for the FBA Label Service and have Amazon apply the labels for you for a per-item fee. For more information, see FBA Label Service.
For eligible products, you can use the manufacturer barcode to track your inventory. For more information, see Use the manufacturer barcode to track inventory.
Any item that requires an Amazon barcode that arrives at a fulfillment center without one will be subject to an unplanned prep service fee. For more information, see Unplanned Prep Services.
You can print Amazon barcodes for your products from the Label Products page when you create a shipment, or at any time from the Manage Inventory page.
If you use a thermal printer, labels are printed immediately. For laser printers, a PDF is generated that you can use to print labels using standard label paper.

For laser printers, the tools in your seller account support the following label sizes:
If your printer attempts to scale the PDF print area when you print your labels, make sure that the printer scaling is set to None or 100%.
