> If you are using Amazon’s FBA program, you need to apply Amazon’s Fulfillment Network Stock Keeping Unit (FNSKU) label. FNSKU labels uniquely identify each unit of your product within Amazon’s fulfillment network.
> Place the FNSKU label on each individual unit of your product. Amazon provides guidelines for label placement, such as making sure the label is scannable. Make sure labels are high quality, legible and can be scanned correctly by Amazon’s systems.
> Use laser printers or thermal printers to print labels for best quality.
