Every published book has something in common — a unique identifier called the ISBN. But how to get an ISBN is something that scares writers.
Whether you’re self-publishing your first novel, distributing academic research, or launching a poetry collection, getting an ISBN number is one of the most important steps in taking your book to the world. It helps ensure your book is correctly listed, searchable, and trackable across bookstores, libraries, and online platforms.
In this guide, you’ll learn exactly how to get an ISBN number, wherever you are in the world — with a special section on how the system works in India, one of the few countries where ISBNs are provided free of cost.
An ISBN (International Standard Book Number) is a 13-digit code that gives every version of your book a distinct identity. It tells booksellers, distributors, and readers everything they need to know about your book — including the title, author, edition, language, format, and publisher.
Think of it like a digital fingerprint for your book. Without it, your book may not be taken seriously by retailers, libraries, or even many readers.
Here’s why ISBNs matter:
Whether you’re in the U.S., the UK, India, Australia, or elsewhere, if you plan to sell or distribute your book, you need an ISBN.
From ghostwriting and editing to publishing and promotion, we take care of every step—including your ISBN.

Here’s a quick overview:
We help you write, polish, publish, promote, and register your ISBN—ensuring your book is ready for global shelves.
Publish ProfessionallyWhile every country has its own forms and procedures, here’s what most authors and publishers need before applying:
Even though every national agency has its own portal and rules, most follow a similar basic process:
Visit the website of your country’s official ISBN body. Create an account as an individual author or registered publisher, depending on how you’re publishing your book.
Upload a photo, valid government ID (or company document), and fill in your address and contact information. Some agencies require verification before you can apply for ISBNs.
Once your account is active, you can apply for one or multiple ISBNs. Each ISBN application usually requires you to enter:
Some agencies may request a copy of your manuscript or book cover to confirm the book exists.
Once approved, you’ll receive a PDF certificate or email with your assigned ISBN(s). You can now:
Our team ghostwrites, edits, formats, designs, registers ISBNs, and markets your book with precision and care.
Bring Your Book to LifeWhile ISBNs are essential, the application process isn’t always intuitive — especially in countries like India where government portals can feel outdated or slow.

Empower My BookWhether you’re publishing from Mumbai, Melbourne, or Montreal, one thing is clear: an ISBN number is your book’s global identity.
It’s what allows your work to be listed, tracked, sold, and discovered — not just by readers, but by retailers, librarians, and academics. It’s not just a formality; it’s the gateway to a more professional publishing experience.
In India, the process is free but may require patience. In other countries, it may require an investment — but one that pays off in long-term visibility and credibility.
If you’re unsure where to begin or just want to publish smarter, support services like Estorytellers can help you do it right — without taking control away from you.
