Amazon FWS uses two types of labels and a packing slip:
Item label— the label that you place on each individual item you send to the Amazon fulfillment center. You do not need to place labels on items that will be commingled.
Shipping label—the label you affix on the outside of the box or carton you ship to the Amazon fulfillment center.
Packing slip— is the single sheet of paper contained in each box or carton you ship to the Amazon fulfillment center.
If you plan to design your own labels and packing slip, be sure to submit printed samples of the designs to FBA. FBA will test your designs for both scannability and rigor (smudging, fading, or smearing).
We recommend that you implement pixel shaving to remove one pixel from each barcode combination. This will increase the readability of the barcode itself and will not affect its symbology.
