Amazon FBA Barcode Generator Guide

What is an FNSKU?

The Fulfillment Network Stock Keeping Unit (FNSKU) is the way Amazon identifies a product as unique to the seller who has sent it to the Amazon fulfillment center. If you are shipping home goods, textiles, or beauty products to an Amazon warehouse, this label is mandatory.

FNSKU Label Requirements

  • Barcode Format: Code 128A
  • Label Size: Must be between 1" x 2" and 2" x 3" (Our 50x30mm preset is perfect).
  • Required Text: The FNSKU alphanumeric code, the Title/Description, and the Condition (e.g., "New").
Pro Tip for FBA Sellers: When uploading your Excel file to our generator, use the "Product Name" column for your Title, and put the word "New" in the "Color" column. Our system will print it perfectly above the Code 128 barcode!
