About ISBN Barcodes
The International Standard Book Number (ISBN) is a unique numeric commercial book identifier assigned to each edition of a publication. The modern ISBN format uses 13 digits (ISBN-13) and always begins with the prefix 978 or 979. ISBN barcodes are encoded using the EAN-13 barcode standard, making them scannable at retail points of sale worldwide.
