If you plan to sell your products on Amazon, you may want to be wary of some of the most common pitfalls that sellers unknowingly fall into. Keep these Amazon selling errors and oversights in mind so you they don’t end up biting you later:

  • No ISBN for Books/Audiobooks. Most books and audiobooks need to have an associated ISBN in order to be on Amazon. Many authors and publishers get these ISBNs themselves, but you can learn more about them at
  • Trying to Sell Large Brand Products. In order to protect consumers from scammers who try to pass off fake products as something from a major brand, Amazon won’t let sellers use a new GTIN for it. The barcode that you purchased might be valid on its own, but it can’t be attached to a product that already has a barcode from that major brand.
  • Brand Registry – Seller Program. It's common for new sellers who are part of brand seller programs to receive an error like this when they first start trying to sell on Amazon. The documents that you receive from will be enough to whitelist you as a reputable seller. Simply open a support ticket with Amazon and provide the documents to customer service.
  • Legacy Brand Registry Sellers. Past listings of branded products tend to be grandfathered into Amazon’s new program, but this isn’t true for new listings created after Amazon’s recent GTIN policy changes. You may need to check the new policy’s wording to determine if your new listings will be affected.
  • Brands Names in Product Bundles. Sellers who offer certain brands’ products in a bundle may find that their listing gets blocked initially. This is Amazon trying to prevent sellers from appearing as though they directly represent the brands included in the bundle. To get around this issue, your business’s name needs to go in the “brand” field of the listing as a whole, while the individual products can have the major brand’s name as part of its description.
