How an ISBN is structured

An ISBN-13 has five parts, for example 978-1-4028-9462-6:

  1. Prefix — 978 or 979 (the EAN 'Bookland' prefix).
  2. Registration group — a country, region or language area (1–5 digits).
  3. Registrant — the publisher or imprint (variable length).
  4. Publication — the specific edition and format.
  5. Check digit — calculated from the other twelve digits.

Because group and registrant lengths vary, hyphens can only be placed correctly with the official range table — which our ISBN converter uses.
