ISBN Barcode Generator

Understanding ISBN Barcodes

An ISBN (International Standard Book Number) is a unique commercial book identifier used worldwide. Our generator creates high-quality, standards-compliant barcodes with correct hyphenation based on the official International ISBN Agency dataset.

Why Hyphens Matter

ISBN hyphens aren't random - they follow a specific structure defined by the ISBN Agency. They separate the ISBN into meaningful parts: prefix, registration group, publisher, title, and check digit. Correct hyphenation helps identify the book's country of origin and publisher instantly.

Benefits of Correct Barcodes

  • • Ensures accurate book identification worldwide
  • • Speeds up inventory management
  • • Reduces errors in book distribution
  • • Facilitates sales tracking and reporting
  • • Improves compatibility with book databases

Where to Buy ISBNs

ISBNs can be purchased from your country's official ISBN agency. In the United States, Bowker is the official ISBN agency. For other countries, you can find your local agency through the International ISBN Agency's website.
