The ISBN (International Standard Book Number) is a global standard for identifying books, used worldwide since the 1970s. For any author, publisher, or self-publisher, an ISBN is essential if the book is to be sold in bookstores, through distributors, or online. But what exactly is an ISBN?
It’s a unique 13-digit code assigned to a specific publication. It identifies the title, publisher, language version, and binding type. ISBNs are used for both printed books and some digital formats.
What Is the Purpose of an ISBN and Who Needs One?
The question of what the ISBN is for usually arises when a book reaches the production stage. It’s not just an organisational tool – it’s a requirement for professional distribution. The ISBN simplifies the work of booksellers, librarians, wholesalers, and search engines. It makes it easier to locate a specific title, prevent confusion, and automate logistics.
That’s why anyone planning to print a book should secure an ISBN early in the project to avoid issues with distribution and promotion down the line.
ISBN vs. Book Barcode – What’s the Difference?
Although often used interchangeably, the ISBN and the book barcode are not the same. The ISBN is a number – a sequence of digits identifying the publication. The barcode is a graphic representation of this number. Thanks to the barcode, the book can be quickly and accurately scanned by sales systems.
Once you’ve obtained your ISBN, you’ll need to generate its barcode. Our book printing website offers a free ISBN barcode generator that allows you to create a ready-to-use graphic file in seconds, perfect for placing on the back cover of your book. It’s a convenient, fully compliant solution with current retail standards.
How to Get an ISBN Before Printing a Book
In the United Kingdom, ISBNs are issued by Nielsen ISBN Agency and must be purchased via the official portal. In the United States, ISBNs are managed by Bowker and are available for purchase through www.myidentifiers.com. In both countries, ISBNs come in single units or bulk packages, depending on your publishing needs.
In Canada, ISBNs are assigned free of charge by Library and Archives Canada. Authors and publishers can register and request ISBNs via the official site. In Australia, ISBNs are distributed by Thorpe‑Bowker and must be purchased through www.myidentifiers.com.au.
Across all four countries, the steps are similar: register with your national ISBN agency, choose or request the number(s), then assign them to your book editions. Once obtained, you can integrate the ISBN into your book files and generate a barcode for print and distribution.
It’s best to integrate the ISBN into your book production process right away to avoid delays and unnecessary corrections. If you’re working with a modern digital printing house, you can combine barcode generation with the entire production workflow, streamlining preparation and reducing the risk of errors.
Does Every Book Need an ISBN?
Surprisingly, not every publication requires an ISBN. If you’re printing a book strictly for personal use or private distribution, you can skip the ISBN without consequence. However, if your goal is to sell the book in bookstores, libraries, on e-commerce platforms, or via distribution networks, having an ISBN becomes essential.
Without it, your distribution options are limited, and retailers may refuse to carry the book. That’s why it’s essential to account for the ISBN and barcode early in the design process. It’s an industry standard that facilitates future marketing and sales efforts.
Print-on-Demand – Complete Support for Authors
In the age of self-publishing and short-run printing, more creators are turning to print-on-demand. This model requires flexibility, fast turnaround, and the ability to update content frequently. A modern book printing service offers end-to-end support – from file preparation and format selection to production. The ISBN barcode generator is a bonus, allowing authors to focus on content without worrying about technicalities.
Thanks to tools like the ISBN barcode generator, your book can be fully prepared for market launch, with professional identification and ready for sale.
ISBN – A Cornerstone of Professional Publishing
Though it may seem like just a sequence of numbers, the ISBN plays a crucial role in the book world. It’s the foundation of professional publishing, enhancing credibility, discoverability, and access to the market. Whether you’re publishing a novel, a how-to guide, or a textbook, the ISBN should be part of your project from the beginning. With services like digital printing and barcode generation, the entire process becomes faster, simpler, and more accessible for any author. ISBNs are more than a formality – they’re a practical tool for making your book a success.
