2. ISBN (International Standard Book Number):

  • A unique identifier for books, used worldwide.
  • A 10 or 13-digit number that identifies a specific book, an edition of a book, or a book-like product (like an audiobook).

3. EAN (European Article Number):

  • Similar to UPC but used internationally.
  • Consists of 13 numeric digits.
  • Used mainly in Europe but accepted globally.

4. ASIN (Amazon Standard Identification Number):

  • Unique blocks of 10 letters and/or numbers that identify items on Amazon.
  • Amazon assigns the ASIN to products when they are created in its catalog.

5. FNSKU (Fulfillment Network Stock Keeping Unit):

  • An Amazon-specific identifier used for inventory management.
  • Assigned to products that are being fulfilled by Amazon (FBA - Fulfillment by Amazon).
  • Unique for each product and seller combination.

6. GTIN (Global Trade Item Number):

How to Obtain Barcodes for Amazon

  • Each barcode is unique and ensures your product's authenticity on Amazon.

2. Using Existing Barcodes:

  • If selling a product that already has a UPC/EAN, you can use the existing code.

3. Requesting an Exemption:

  • For products that don't have a UPC/EAN, you can request a GTIN exemption from Amazon.
  • Requires a valid reason, such as handcrafted items.

Using Barcodes on Amazon

1. Listing Products:

  • When listing a product on Amazon, enter the product’s UPC, EAN, ISBN, or ASIN.
  • This ensures the product is correctly cataloged.

  • Amazon provides a service to label products with an FNSKU for a fee.

3. Labeling Products:

  • Barcodes must be printed and affixed to the product packaging.
  • Must be easily scannable and meet Amazon’s size and quality requirements.
