This blog post covers what to do if your Amazon listing has been pulled due to GS1 UPC issues. Sometimes, when creating a new listing or adding a new offer to an existing listing, you may run into this issue. This blog post will cover the specific issue of the error message “This ASIN has GTIN codes that do not match the brand associated with the ASIN.” It is vital as a seller to clear this error so you can activate your listing and start selling on Amazon. It is important to have active and compliant listings so customers can find your products. Amazon enforces issues like GTIN compliance to ensure Amazon is a fair marketplace, and to avoid any fraudulent listings. If you do not provide GTIN proof and clear this error with Amazon, you will not be able to list your product. This can result in disappointment among customers looking for your products. If Amazon did not enforce this rule, there could be many fraudulent sellers on Amazon using UPC GTIN codes that do not belong to them, which would cause a lot of errors and confusion on the platform. This post will cover what causes this error, what to do when you face this error, and the necessary items to appeal it.
