About us & Policies

The website isbn-international.com is an independent scientific organization dedicated to verifying the authenticity and legitimacy of published books and issuing official publication certificates. Its services are provided free of charge, with no fees required to obtain a certificate. The organization is financially supported by international scientific institutions. All issued certificates include a unique certificate number that can be verified through the website.
This organization does not issue any certificate without a certificate number, and any certificate issued without such a number shall be deemed invalid.

The International Certificate of Book Publication is distinct from an ISBN. While all books are required to have an ISBN, not all publishers are eligible to obtain this certificate for their publications. If you require an ISBN, please visit isbn-international.org to obtain it.
