FNSKU (Fulfillment Network Stock Keeping Unit)

Is FBA Dead?

The FNSKU is an acronym for Fulfillment Network SKU or Fulfillment Network Stock Keeping Unit. The FNSKU is the way that Amazon identifies a product as unique to the seller that has sent it to the Amazon fulfillment center.

Every product that is processed through an Amazon fulfillment center is given this unique identifier. The FNSKU is printed on product-level labels. When the FNSKU and the ASIN match, this is an indication to Amazon that the items are Stickerless, Commingled Inventory.
