Using 2D barcodes for box content information

You can use 2D barcodes to provide the product quantities and expiration dates (if applicable) for each box in your shipment. If you use 2D barcodes, you do not need to provide box content information through Seller Central. Instead, you can select Use 2D barcodes in the shipment creation workflow and then apply a 2D barcode to each of your boxes. We can then simply scan your barcodes to determine the contents of a specific box.

Providing box content information helps reduce the time needed between your products arriving at the fulfillment center and your products being available for sale. 2D barcodes are especially useful for sellers drop shipping inventory directly from suppliers. Your supplier can provide box information without having access to the details of your FBA shipment. If you manage high-volume operations, 2D barcodes will scale to larger shipments more easily.

Important: To enable the 2D barcode option in Seller Central, go to your Fulfillment by Amazon settings, then to your Inbound Settings page. Please note that you will need to use a third-party application or website to generate 2D barcodes. 2D barcodes do not replace Amazon shipping labels. Amazon shipping labels are still required.

  2. FBA Shipment ID (also referred to as the PO) (Code: PO)
  3. Item ID (Code: ASIN, UPC, EAN, ISBN, or FNSKU)
  4. Quantity (Code: QTY)
  5. Expiration date, if applicable, in YYMMDD format (Code: EXP)

A colon should be used between a code and its value. Each segment should be separated by a comma.

Please note the following:

  • Use uppercase letters for all data, as shown above.
  • Do not enter any spaces in the data.
  • Enter a value for each field. Null or zero values are not valid.
  • Do not list an ASIN with a quantity of 0. Exclude the ASIN from the data.
  • Do not pack more than 100 different ASINs in a single box.
  • Provide expiration dates in YYMMDD format.
  • Pack each box with only one expiration date per ASIN. If you have units of an ASIN with multiple expiration dates, then those units will need to be packed in different boxes so that each box only has one expiration date per ASIN.
