Navigating FBA Labeling: Essential Guidance for Private Label Sellers

For private label sellers leveraging Amazon’s FBA (Fulfillment by Amazon) program, understanding the intricacies of FBA labeling is crucial. FBA labeling refers to the process of affixing unique product labels to items sent to Amazon’s fulfillment centers. This practice ensures efficient inventory management, order fulfillment, and adherence to Amazon’s guidelines. Here’s a comprehensive guide outlining key aspects of FBA labeling that every private label seller should know.

Labeling Requirements and Guidelines

Amazon has specific labeling requirements that sellers must adhere to when sending products to FBA centers. Each unit must display a scannable barcode, either a UPC (Universal Product Code), EAN (European Article Number), or an Amazon FNSKU (Fulfillment Network Stock Keeping Unit) barcode. FNSKU barcodes are unique to each seller’s account and are essential for inventory tracking within Amazon’s network.

Labeling Methods

Sellers have two primary options for labeling their products:

  1. Manufacturer Barcode (Commingled Inventory):
    • Some sellers choose to use the manufacturer’s barcode, allowing their items to be commingled with identical products from other sellers. However, this method may pose risks, as the inventory could be mixed with other sellers’ stock, potentially leading to issues with item condition or authenticity.
  2. FNSKU Label (Stickered Inventory):
    • Using FNSKU labels involves affixing Amazon-specific labels with the unique FNSKU barcode directly onto each unit. This method ensures that your inventory remains separate and distinct within Amazon’s fulfillment centers, reducing the risk of inventory commingling and potential issues related to other sellers’ products.

Labeling Process and Best Practices

To properly label products for FBA, sellers should follow these best practices:

  1. Generate and Print FNSKU Labels:
    • Generate FNSKU labels through the Amazon Seller Central platform and print them using a high-quality printer on adhesive label sheets.
  2. Correct Placement:
    • Affix the FNSKU label on a flat, clean surface of the product packaging where it’s easily scannable. Avoid covering important product information or barcodes provided by the manufacturer.
  3. Quality Control:
    • Ensure labels are applied accurately and securely to prevent damage or peeling during transit. Conduct regular quality checks to confirm that labels are readable and scannable.
  4. Packaging Requirements:
    • Comply with Amazon’s packaging guidelines, including using suitable packaging materials to protect products during shipment to FBA centers. When handling shipments for larger or more complex items, such as vehicles, it’s essential to use a specialized service like to ensure safe and efficient transportation.

Importance of Accurate Labeling

Accurate FBA labeling is vital for seamless inventory management and order fulfillment. Incorrect or missing labels can result in delays, misplacement of inventory, or even rejection of shipments at Amazon’s fulfillment centers, leading to disruptions in sales and customer dissatisfaction.


For private label sellers utilizing Amazon’s FBA program, understanding and implementing proper FBA labeling practices is fundamental. Adhering to Amazon’s guidelines, choosing the appropriate labeling method, and ensuring accurate and consistent labeling across products are key to streamlining operations, maintaining inventory integrity, and delivering a positive customer experience. By prioritizing FBA labeling compliance, private label sellers can optimize their FBA experience and contribute to successful sales on the Amazon platform.
