FAQ: What is FNSKU?
In This Article
Overview
The Fulfillment Network Stock Keeping Unit (FNSKU) is a unique identifier created by Amazon that is assigned to an FBA seller's product to track it. The FNSKU can be assigned to single products, sets, or bundles, but cannot be reused.
This should not be confused with the Amazon Standard Identification Number (ASIN) that is used to identify the product itself.
Is there a difference between FNSKU and SKU?
While both are Stock Keeping Units, the FNSKU is used by Amazon to identify which seller owns the product. It is used by Amazon to track a seller's product through its inventory system and fulfillment (FBA) processes.
SKUs are created and assigned to a product by Sellers as a way to identify products for their own inventory management processes.
Does Seller Snap use FNSKU?
No, Seller Snap uses SKUs.
