FreeISBN serves as a distinctive identifier assigned to each book title by its publisher. It acts as a tracking tool for sales and provides insights into the book's distribution channels. FreeISBN numbers are universally acknowledged as a means of book identification and are standardized by the International Organization for Standardization (ISO) to distinguish between various editions and formats of a book. Comprising 13 digits, an ISBN begins with a country code, followed by the publisher code, and then the title code, along with any additional codes representing specific book information.
