I get an “8541 – Product Already Exists” error or an “5461 – ASIN Creation Violation” error when listing on Amazon. What should I do?

If you are the product brand owner, or have the right to assign a GTIN, you should first open a ticket with Amazon Selling Partner Support. In the ticket you should include the following information from the first communication, to ensure that the ticket ends up in the correct ticketing queue.

Your GS1 license certificate for the prefix
Your trademark certificate (if applicable)
Statement that this is a GTIN hijacking scenario with the text of the error message and error code from Amazon (error code: 8541)
A screenshot of the product that is misusing the GTIN
If possible, the ASIN/link for the product that is misusing the GTIN

If the response from Amazon Selling Partner Support is not helpful, close the ticket and re-open it with all the information listed above. The ticket may have ended up in the wrong ticket queue.

If you encounter this error, it means someone else is likely already using the same GS1 GTIN on Amazon and that the product data you entered does not match with the product already online. We call this “GTIN hijacking”.
