Frequently Asked Questions
What is an ISBN?
ISBN stands for International Standard Book Number. It's a unique 10 or 13-digit numeric identifier assigned to books worldwide to make them easily identifiable.
Where can I find ISBN on a book?
The ISBN is typically found on the back cover above the barcode, or on the copyright page inside the book. Digital books also display their ISBN in the product details.
What's the difference between ISBN-10 and ISBN-13?
ISBN-13 is the current standard (13 digits starting with 978 or 979). ISBN-10 is the older format (10 digits) used before 2007. Our system automatically converts between formats for your convenience.
Example of ISBN and barcode
Here is a standard EAN-13 barcode commonly found on the back of books. The 13-digit ISBN is printed above the bars, while the barcode itself encodes this number for scanning by retailers and libraries.
