Hello @Seller_tCnjximGNbnXq,

Thank you for your Post. I wanted to share some additional reference information with our help pages in case you wanted to learn more about the Product ID (GTIN) requirements for Books and the Books ISBN Requirements – FAQs help page.

Lastly, you may be interested in looking into Author Central to see if that is a way that you would like to have your book listed on Amazon.

Please let me know if you have any additional questions or concerns.

Cheers,

Micah
