UCC-128 Labels in Amazon FBA: What Sellers Need to Know

UCC-128 labels, now more commonly known as GS1-128 labels, play a crucial role in Amazon's Fulfillment by Amazon (FBA) program. These standardized shipping labels contain essential information that helps Amazon efficiently receive, track, and manage inventory in their fulfillment centers. Here's what FBA sellers need to understand about UCC-128 labels:

What is a UCC-128 Label?

A UCC-128 label is a type of barcode label used for shipping and logistics purposes. It encodes important details about a product or shipment using a series of Application Identifiers (AIs) and corresponding data fields. The label includes information such as:

  • Serial Shipping Container Code (SSCC)
  • Global Trade Item Number (GTIN)
  • Quantity
  • Batch/lot number
  • Production date
  • Expiration date

Why UCC-128 Labels Matter for FBA

Amazon requires UCC-128 labels on shipments to their fulfillment centers for several reasons:

  1. Efficient receiving: The labels allow Amazon to quickly scan and process incoming inventory.
  2. Accurate tracking: Each label contains unique identifiers that help Amazon track items throughout their fulfillment network.
  3. Inventory management: The encoded information aids in managing stock levels and product details.
  4. Order fulfillment: Proper labeling ensures the right items are picked and shipped to customers.

Creating UCC-128 Labels for FBA

To create compliant UCC-128 labels for Amazon FBA:

  1. Use Amazon's label generator or approved third-party software.
  2. Ensure labels include required information like FNSKU (Fulfillment Network Stock Keeping Unit) for non-commingled inventory.
  3. Print labels on high-quality, self-adhesive paper with a thermal or laser printer.
  4. Adhere to Amazon's size and placement guidelines for labels on products and shipping cartons.

Commingled vs. Labeled Inventory

FBA sellers have two options for inventory management:

  1. Labeled Inventory: Each item receives a unique FNSKU label, ensuring it's attributed to your seller account.
  2. Commingled Inventory: Eligible new products with standard UPC/EAN barcodes can be pooled with identical items from other sellers. This option may expedite order fulfillment but has specific requirements.

Best Practices for UCC-128 Labels in FBA

To maximize efficiency and avoid issues:

  • Double-check label accuracy before applying
  • Ensure barcodes are scannable and not obscured
  • Follow Amazon's guidelines for label placement
  • Consider using label printing services for large volumes
  • Regularly update your inventory management software

By mastering the use of UCC-128 labels in your FBA operations, you can streamline your shipping process, reduce errors, and improve your overall performance as an Amazon seller. Remember that while creating compliant labels may seem complex at first, it's a crucial step in running a successful FBA business.
