FAQ

• What is an ISBN?

  An ISBN is an International Standard Book Number, which consists of 10 digits or 13 digits. It uniquely identifies books published internationally.

  Every ISBN consists of 5 parts: an EAN prefix, a registration group, a registrant, a publication and a check digit.

• What is the difference between an ISBN-10 and ISBN-13?

  The main difference is that ISBN-10 is the older system whereas ISBN-13 is the new system. So ISBN-13 has an EAN prefix, but ISBN 10 doesn't, and the check digit is also different.
