What Is an ISBN and How to Get One for Your Book

If you’re planning to publish a book, whether in print or as an eBook, one of the most important steps is obtaining an ISBN. But what exactly is an ISBN, and why is it so crucial for your book’s success? An ISBN (International Standard Book Number) is a unique identifier that helps booksellers, libraries, and distributors track and manage your book in the marketplace. Without one, your book may struggle to get noticed.

In this guide, we’ll explain what an ISBN is, why you need it, and how to get one for your book. Whether you’re self-publishing or working with a traditional publisher, understanding the ISBN process will ensure your book is properly registered and ready for distribution.

What Is an ISBN?

An ISBN (International Standard Book Number) is a unique identifier for books, designed to make it easier for publishers, booksellers, and libraries to track and catalog books. Think of it as a digital fingerprint for your book. Each ISBN is specific to a particular edition and format, so a hardcover version, paperback, and eBook would each have a distinct ISBN.

Purpose of an ISBN

The main purpose of an ISBN is to provide a standardized way of identifying books across the globe. When your book has an ISBN, it becomes part of a larger international system that helps booksellers and libraries manage inventory, process orders, and locate books in catalogs.

Having an ISBN is essential if you plan to sell your book through major retailers like Amazon, Barnes & Noble, or libraries. It allows these entities to track your book’s sales and make it easily discoverable to readers.

Components of an ISBN

An ISBN is made up of several components that together uniquely identify your book. Here’s a breakdown:

• Prefix Element: A 3-digit number (usually “978” or “979”) that indicates the book’s international status.
  
• Registration Group: This identifies the country, geographical region, or language area of the publisher (e.g., U.S. publishers will have “0” or “1”).
  
• Publisher Code: This identifies the publisher or imprint associated with the book.
  
• Title ID: This identifies the specific title, edition, or format of the book.
  
• Check Digit: A single digit that ensures the ISBN is correctly formatted and valid.

Each of these parts plays a crucial role in helping booksellers and distributors locate your book and track its sales accurately.

Why Do You Need an ISBN?

An ISBN is more than just a number, it’s a vital tool for ensuring your book is properly cataloged, distributed, and sold. Here’s why having an ISBN is essential for any serious author looking to publish and sell their book.

1. Unique Identification

The ISBN provides your book with a unique identifier that sets it apart from others in the global market. This ensures that booksellers, libraries, and distributors can easily identify your book in a catalog, making it more likely to be found by readers.

2. Retail and Distribution

If you want your book to be available in major bookstores, online retailers, or libraries, an ISBN is necessary. Retailers like Amazon, Barnes & Noble, and other bookshops require an ISBN to list and sell your book. Without one, your book may not be accepted by these platforms, limiting its potential reach.

3. Tracking Sales and Royalties

An ISBN is crucial for tracking your book’s sales and royalties. Through your ISBN, you can monitor how your book is doing across various platforms and ensure you’re paid accurately for every copy sold. It also helps to track inventory and manage your book’s availability, which is especially important if you’re selling through multiple channels.

4. Professionalism and Credibility

An ISBN signals professionalism and shows that you’re serious about publishing. It provides a level of credibility and helps distinguish your work from self-published books that may not have an ISBN. Having an ISBN on your book makes it easier for potential readers, publishers, and retailers to take you seriously.

5. International Reach

If you plan to distribute your book internationally, an ISBN is necessary for global recognition. It ensures that your book can be tracked and sold not just locally but also across the world. The ISBN system is recognized in over 150 countries, making it a key tool for reaching a broader audience.

How to Get an ISBN for Your Book

Now that you understand the importance of an ISBN, let’s break down the steps to get one for your book. The process is relatively simple, but there are a few key things to keep in mind to ensure you do it correctly.

Step 1: Determine Whether You Need an ISBN

Before you proceed with obtaining an ISBN, it’s important to determine if you actually need one:

• Self-Publishing: If you’re self-publishing your book, you will need to acquire an ISBN to ensure it’s properly cataloged and distributed.
• Using a Publisher or Platform: If you’re using a platform like Amazon KDP or IngramSpark, they may provide you with a free ISBN, but be aware that this ISBN will be registered to the platform, not to you as the author. If you want to retain full control over your ISBN, it’s better to purchase one yourself.

Step 2: Registering Your ISBN

You can obtain an ISBN by purchasing it directly from the official agency in your country. In the United States, the official provider is Bowker, while other countries have their own designated ISBN agencies (e.g., Nielsen in the UK, ISBN Canada for Canada).

Here’s how to register your ISBN:

• Visit the Official ISBN Agency Website: Go to the ISBN agency’s website for your country (e.g., www.myidentifiers.com for U.S. authors through Bowker).
• Create an Account: You’ll need to set up an account to purchase and manage your ISBNs.
• Purchase Your ISBN: You can buy a single ISBN or a package of ISBNs if you plan to publish multiple books. A single ISBN usually costs around $125, but you can get bulk discounts if you’re purchasing a larger package.

Step 3: Choosing the Right ISBN Package

When purchasing an ISBN, you can choose between buying a single ISBN or a bulk package:

• Single ISBN: Ideal for authors publishing just one book. It’s a straightforward and cost-effective option.
• Bulk ISBNs: If you plan to publish several books, you can save money by purchasing a bulk package (e.g., 10, 100, or 1,000 ISBNs). This is useful for authors who anticipate releasing multiple titles or formats in the future.
• Different Formats: Keep in mind that each format of your book (print, eBook, audiobook, etc.) will require a separate ISBN. For example, if you publish your book as both an eBook and paperback, you’ll need two ISBNs—one for each format.

Step 4: Assign Your ISBN to Your Book

Once you’ve purchased your ISBN, you’ll need to assign it to your book. This involves entering specific information about your book into the ISBN registry, such as:

• Book Title and Subtitle
• Author’s Name
• Publisher Information (if applicable)
• Book Format (eBook, paperback, hardcover, etc.)
• Genre and Keywords
• Price (if required)

Ensure the information you provide is accurate, as this will be used to track your book across various platforms.

Step 5: Keep Track of Your ISBN

After you’ve registered your ISBN and assigned it to your book, make sure to keep track of it. You may need it when distributing your book through retailers or when making updates to your book’s listing. If you ever need to change details like your publisher or author name, you can update the information in the ISBN registry.
