ISBN Assignment

ISBN (International Standard Book Number) is a 13-digit numeric code that serves as an internationally applicable unique identifier for books. The code captures information regarding the book’s publisher, title, language, edition, and version. Magazines, academic journals, and other periodicals do not get ISBNs. Instead, they are issued 8-digit ISSNs (International Standard Serial Numbers).

The ISBN helps customers identify and order the exact book they want to purchase. Libraries, bookstores, online retailers, distributors, and wholesalers depend on this unique identifier to track purchases and sales too.
