Item label specifications

When labeling your items, follow these guidelines to ensure that your items can be processed in a timely manner after they reach the fulfillment center:

  • Cover all existing barcodes. Unless you are sending stickerless, commingled inventory, be sure to cover the existing barcodes on each item.
  • Use the proper print media for your printer. Each label must be readable and scannable for at least 24 months. This means that the label must not smudge or fade over that period of time. Using laser paper and laser toner with a laser printer, for example, can help keep labels readable and scannable.

Item label example

Item label

The label that you place on each item must include the following information:

  1. Barcode, with appropriate quiet zone areas (the clear area surrounding a bar code).
  2. String identifier for the barcode.
  3. Title and description.
  4. Condition (for example, USED).
Note: You can include optional, seller-specified information at the bottom of the item label. This area is reserved for text only. Do not use any additional barcodes. Any information that you provide in addition to the label information listed here could have a negative impact on the accuracy and speed of inventory tracking.
