Thinking of publishing a book?
One of the first questions authors ask is — what is an ISBN and do I need one to publish my book?Here’s a clear, experience-based guide to help you understand what an ISBN is, why it matters, and how to get one in India.
What is an ISBN?
An ISBN (International Standard Book Number) is a unique 13-digit code assigned to every published book edition and format.
It helps booksellers, libraries, and online retailers identify and manage your book efficiently for ordering, cataloguing, and sales tracking.
If your book is available in any of the three formats — paperback, hardcover, and eBook — each format will need its own ISBN.
Why is an ISBN Important?
An ISBN is essential if you want your book to be:
- Listed on platforms like Amazon, Flipkart, and Google Books
- Distributed through bookstores and libraries
- Professionally recognized and trackable
Without an ISBN, your book cannot be distributed or catalogued by most retailers and libraries.
Is ISBN Mandatory in India?
An ISBN is not legally mandatory, but highly recommended.
Without it, your book won’t appear in official catalogues or searchable databases, limiting its reach and visibility.
Do eBooks Need an ISBN?
While it is optional, an ISBN for eBooks is strongly advised.
It improves discoverability across platforms like Kindle and Google Play Books and helps track sales accurately.
How to Get an ISBN in India
You can obtain an ISBN in two ways:
- Through Your Publisher – Your publisher (like Zorba Books) can apply for and assign an ISBN as part of the publishing process.
