Correct labelling is crucial for smooth delivery to Amazon and helps reduce lead times and costs.
Why are barcodes important?
- Reduces lead time by up to 18%
- Increases sales and customer reach
- Enables tracking of items throughout the shipping process
Types of barcodes:
- Manufacturer Barcode: EAN, UPC, GTIN, ISBN (for commingled inventory)

- Amazon Barcode: ASIN (BASIN) for commingled inventory, FNSKU (XASIN) for labelled inventory
- Transparency Labels: Contain both EAN and ASIN/FNSKU

Where can I print Amazon barcodes?
- In the “Send to Amazon” workflow
- Under “Manage Inventory” or “Fulfilled by Amazon Inventory”
