What is an ISBN Hyphenator?
An ISBN Hyphenator is a tool that formats an ISBN-13 by inserting hyphens in the right places. The hyphens separate the ISBN into meaningful parts: the prefix, registration group, registrant, publication, and check digit. These divisions aren’t arbitrary—they’re determined by the latest ISBN range data from the International ISBN Agency.
Our hyphenator ensures your ISBN-13 is presented in a standardized, professional format, making it easier to read, share, and use.
How to Use the ISBN Hyphenator
Hyphenating your ISBN-13 is simple with our tool:
- Enter Your ISBN-13: Type or paste your unhyphenated ISBN-13 (e.g., 9780747532699).
- Click Hyphenate: Press the “Hyphenate” button to process it.
- Get Your Result: See your ISBN-13 with hyphens added correctly (e.g., 978-0-7475-3269-9).
Note: The tool works with ISBN-13 numbers only (starting with 978 or 979) and supports ISBNs from all registration groups worldwide.
Why Hyphenate an ISBN?
Hyphens in an ISBN serve a purpose beyond aesthetics:
- Readability: Breaks the 13-digit number into clear, manageable sections.
- Professionalism: Properly formatted ISBNs meet industry standards for publishing and distribution.
- Accuracy: Reflects the official structure of the ISBN, reducing confusion in catalogs or databases.
- Global Compatibility: Ensures your ISBN aligns with international formatting rules.
Whether you’re an author, publisher, or bookseller, a correctly hyphenated ISBN enhances your book’s presentation and credibility.
How Our Hyphenator Works
Hyphens in an ISBN-13 aren’t placed randomly—they follow a structure defined by the International ISBN Agency:
- Prefix: The first 3 digits (e.g., 978 or 979).
- Registration Group: Identifies the country or language area (e.g., 0 for English-speaking regions).
- Registrant: Assigned to the publisher.
- Publication: Specific to the book or edition.
- Check Digit: The final digit for validation.
Our tool uses the latest ISBN range data to determine where hyphens belong, ensuring precision for ISBNs from any registration group—tested and verified by book publishing experts using diverse examples from the List of ISBN Registration Groups.
Example:
- Input: 9780306406157
- Output: 978-0-306-40615-7

No, our hyphenator is designed for ISBN-13 only. For ISBN-10 needs, try our ISBN Converter.
