What is an ISBN?
An ISBN (International Standard Book Number) is a unique numeric identifier for books. Introduced in 1970, it helps publishers, booksellers, libraries, and readers locate and order specific titles. Each edition and variation (like hardcover, paperback, or ebook) of a book requires its own distinct ISBN.
Originally 10 digits (ISBN-10), the standard expanded to 13 digits (ISBN-13) in 2007 to increase capacity. Our tool works with both formats.
