FNSKU Labeling Services

FNSKU labeling is a mandatory step for most products sent to Amazon Fulfillment Centers under the FBA program. Each unit must be labeled with a unique FNSKU barcode that links the product to your seller account. Incorrect or missing labels can lead to receiving delays, relabeling fees, or rejected inventory at Amazon warehouses.

This service is essential for Amazon sellers sourcing products from US retailers, wholesalers, or private suppliers. When items arrive without proper FNSKU labels-or with manufacturer barcodes only-professional relabeling ensures full compliance with Amazon’s inbound requirements.

Fulfillment Hub provides accurate and consistent FNSKU labeling as part of a structured FBA prep workflow. We apply labels according to Amazon standards, ensuring scannability, correct placement, and unit-level consistency before inventory is shipped to Amazon.

How FNSKU Labeling Works

After your inventory arrives at our warehouse, each product unit is checked in and matched to your prep instructions. FNSKU labels provided by you-or generated based on your shipment plan-are printed and applied to each unit in accordance with Amazon guidelines.

Labels are placed to fully cover existing barcodes when required, preventing scanning conflicts at Amazon Fulfillment Centers. This step is critical for accurate receiving, inventory tracking, and order fulfillment within the Amazon ecosystem.

Once labeling is completed, products are prepared for the next stage of FBA prep, such as polybagging, bundling, or shipment to Amazon. This streamlined process helps reduce inbound errors and keeps your inventory moving without unnecessary interruptions.

Who Benefits from FNSKU Labeling

FNSKU labeling is required for most Amazon sellers using FBA, especially those sourcing from retail arbitrage, online arbitrage, wholesale suppliers, or private label manufacturers. It is particularly important when products are shipped directly from third-party sellers or stores that do not support Amazon-specific labeling.

Sellers managing multiple SKUs or frequent inbound shipments benefit from outsourced labeling by maintaining consistency and reducing the risk of costly Amazon receiving issues.
