Amazon requires that you affix clear and correct labels to each carton (package) with certain shipment details so that they can receive your shipment effectively at their fulfillment centers.
You must use a shipping (ASN) label that includes the shipment level information of the ASN/BOL number in text and barcode. You can use the label printing option in Vendor Central to print shipping (ASN) labels or print your own.
Even if you print the provided AMZNCC/SSCC labels and stick them on each package, you must also print and stick ASN labels on each small parcel shipment, and on each pallet when sending palletized shipments.
Pallet labels should be placed squarely (not on an angle) on two sides of the pallet on the forklift entry sides. If the pallet is wrapped in plastic, the pallet labels must be placed on the outside of the plastic wrap.
