Use an Amazon barcode to track inventory

Amazon systems are barcode-driven. Each unit you send to a fulfilment centre requires a barcode so that it can be tracked throughout the fulfilment 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, then you can sign up for the FBA Label Service and have Amazon to 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 fulfilment centre without one will be subject to an unplanned prep service fee. For more information, see Unplanned Prep Services.

Important: Failure to comply with FBA product preparation requirements, safety requirements, and product restrictions may result in the refusal of inventory at the Amazon fulfilment centre, disposal or return of inventory, blocking of future shipments to the fulfilment centre, or charging for preparation or for non-compliance at the fulfilment centre.

How to Label Products (PDF)

Print Amazon barcodes

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, then labels are printed immediately. For laser printers, a PDF is generated that you can use to print labels using standard label paper.

To print Amazon barcodes from the Label Products page:

Select the shipment that you want to work on from the Shipping Queue page.
In the Items column, verify the number of each product that you want to send.
At the bottom of the page, click Print labels. For thermal printers, the labels will be printed automatically. For laser printers, a PDF will be generated for use with label paper.

To print Amazon barcodes from the Manage Inventory page:

Select the products in the left column.
Select Print Item Labels from the Action on Selected Item(s) drop-down menu.

Amazon barcode requirements

When printing Amazon barcodes on labels, make sure that the printed labels include:

Sufficient white space around the Amazon barcode and related text: (0.25 inch on the sides and 0.125 inch on the top and bottom)
ASIN or FNSKU
Product name
Item condition

Note: Amazon barcodes that have been printed directly onto the product packaging must meet these requirements as well.

If you are the product manufacturer or brand owner and you want to print barcodes directly onto the product packaging, then apply for your own GS1 standard UPC barcode. For more information, see GS1.

Label placement requirements

When you are ready to affix barcodes to your products, make sure that you:

Put the correct barcode on each item.
Cover all other visible barcodes, except for any serial number barcodes or Transparency authentication code labels.
Place the barcode on the outside of any prep materials.
Do not place the barcode on a curve or corner of the package.
Allow 0.25 inch between the edge of the label and the edge of the packaging.
Ensure that each item in a case pack has an Amazon barcode and any barcodes on the case have been removed.

Important: Failure to follow label placement requirements can cause delays in processing and may result in unplanned prep service fees.

Printer requirements

The tools in your seller account are optimised for thermal printers. You can also use laser printers. Do not use inkjet printers to print Amazon barcodes.

Tip: Amazon fulfilment centres currently use Zebra GX430t model printers with a direct thermal setting.

Each label must be readable and scannable for 24 months. The following guidelines will help to ensure that the label you print will not smudge or fade:

Periodically test your Amazon barcodes by scanning them
Use a printer with a print resolution of 300 DPI or greater
Periodically test, clean, and replace your printer heads

Label paper requirements

All Amazon barcodes must be printed in black ink on white, non-reflective labels with removable adhesive. Dimensions must be between 1 inch x 2 inches and 2 inches x 3 inches (for example, 1 inch x 3 inches or 2 inches x 2 inches).

For laser printers, the tools in your seller account support the following label sizes:

21 labels per page (63.5 mm x 38.1 mm on A4)
24 labels per page (63.5 mm x 33.9 mm on A4, 63.5 mm x 38.1 mm on A4, 64.6 mm x 33.8 mm on A4, 66.0 mm x 33.9 mm on A4, 70.0 mm x 36.0 mm on A4, 70.0 mm x 37.0 mm on A4)
27 labels per page (63.5 mm x 29.6 mm on A4)
30 labels per page (1 inch x 2 5/8 inches on US Letter)
40 labels per page (52.5 mm x 29.7 mm on A4)
44 labels per page (48.5 mm x 25.4 mm on A4)

If your printer attempts to scale the PDF print area when you print your labels, then make sure that the printer scaling is set to None or 100%.
