Use an Amazon barcode to track inventory

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.

For eligible products, you can use the manufacturer barcode to track your inventory. For more information, see Use the manufacturer barcode to track inventory.

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, 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:

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

To print Amazon barcodes from the Manage Inventory page:

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

Amazon barcode requirements

Amazon barcodes must remain scannable for a minimum of 24 months. Following the printer and label requirements will help ensure the longevity of your Amazon barcode.

When printing Amazon barcodes onto 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 SKU
• Product name
• Item condition

Label placement requirements

All other barcodes on the package must be covered, including the manufacturer barcode. Failure to do so can cause delays in processing and may result in unplanned prep service fees.

• Put the correct barcode on each item.
• Cover all other visible barcodes.
• 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.

Printer requirements

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

We also recommend that you:

• 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 1inch x 2 inches and 2 inches x 3 inches (1 inch x 3 inches or 2 inches x 2 inches, for example).

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, make sure that the printer scaling is set to None or 100%.
