FNSKU (Fulfillment Network Stock Keeping Unit) is Amazon's internal barcode that identifies your specific product in the FBA network. Unlike a UPC/EAN, it ties inventory to your seller account — preventing commingling with other sellers' stock.
Go to Seller Central → Inventory → Manage Inventory. Click the product, then "Print item labels" — your FNSKU is displayed there. It always starts with X followed by 9 alphanumeric characters (e.g., X001234567).
Required if you've opted for 'Seller-labeled' inventory instead of Amazon-labeled. FNSKU-stickered products must have the label covering the original UPC/EAN barcode before being sent to an Amazon fulfillment center.
Amazon recommends 1" × 2.625" labels (Avery 40403 or equivalent). At minimum, labels must be at least 1" × 1". Always print at 300 DPI for reliable scanning by Amazon warehouse staff.
