What Is a Fulfillment Network Stock Keeping Unit (FNSKU)?

A Fulfillment Network Stock Keeping Unit (FNSKU) is a unique identifier used by Amazon to distinguish and track products within its fulfillment network. Each product that is enrolled in the Fulfillment by Amazon (FBA) program is assigned a specific FNSKU, which is a unique alphanumeric code. The FNSKU is vital for accurate inventory management, order fulfillment, and to ensure that the correct product is associated with a seller's listing on the Amazon platform.

The FNSKU is typically applied as a barcode label to each unit of a product before it is sent to an Amazon fulfillment center. This barcode assists in automating the tracking and identification of products as they move through the fulfillment network. It plays a key role in the order picking and packing process, allowing Amazon's systems to match the physical product with the corresponding listing and customer order, ensuring accuracy and efficiency in the fulfillment process.

One significant advantage of using FNSKU is that it helps prevent commingling of inventory. Commingle is a feature where identical products from different sellers are mixed in Amazon's fulfillment centers. By using unique FNSKUs, sellers can ensure that only their specific inventory is associated with their listings, reducing the risk of confusion or fulfillment errors that could arise from commingled inventory. The FNSKU system is an integral part of Amazon's commitment to maintaining the accuracy and integrity of its vast and diverse product catalog.

FAQs

No. Amazon requires products enrolled in the FBA program to be labeled with the assigned FNSKU. This unique identifier is vital for accurate tracking, inventory management, and preventing commingling within Amazon's fulfillment network.

Yes, you can print FNSKU labels at home. Amazon provides the option for sellers to print their FNSKU labels, and it is a common practice for sellers to generate and affix these labels to their products before sending them to Amazon's fulfillment centers.

In general, FNSKU labels are required for each unit of a product sent to Amazon's fulfillment centers. However, certain items, such as books, music, and video products with scannable barcodes, may be eligible for Stickerless, Commingled Inventory (SCI). In such cases, the decision to use FNSKU or participate in SCI depends on the seller's preferences and product category.
