Does a Self-Published Book Need an ISBN?

All books, including self-published ones, need a 13-digit ISBN number that allows booksellers, libraries, and publishers to identify it worldwide. It’s a system that began in the United Kingdom in 1967 with nine-digit numbers and over time grew to be a global system embraced by all in publishing, book sales, and libraries.

The system allows each book to be uniquely identified compared to the tens of millions of others in existence. Having a number is required to get your book into bookstores, libraries, and many other distribution channels. It’s a worldwide and industry-wide system used and embraced by everyone.

Free ISBNs from Self-Publishing Platforms

If you only plan to publish your work as an eBook on Amazon, you may be able to get by only with the ASIN number they’ll issue. For everything else, you need an ISBN number for books. Other self-publishing platforms will offer a free or low-cost ISBN but make sure you read the fine print for any limitations.

On-demand and self-publishing companies such as IngramSpark, Drafe2Digital, and Smashwords provide free of low-cost numbers, but there are limits. For example, if your self-published book has a number assigned by one platform and your want to sell books through another channel, it may not accept the free number. But if you register your own ISBN number directly, it can be used anywhere which is a significant advantage.

An ISBN Agency Exists for Virtually Every Country

The United States and the United Kingdom have appointed Bowker (U.S.) and Nielsen (UK) as the ISBN agency of record. Each charges authors and publishers a fee for numbers with volume discounts available that seriously reduce the cost for each number. In Canada and other countries, numbers are free.

In countries like the U.S. and UK, volume discounts can bring down the cost per number significantly. As you’re weighing how to get an ISBN number, keep in mind that each version of your book needs a distinct number – published copies, ebooks, audiobooks. It’s easy to see how buying in bulk can make sense. Also, if you don’t use all the numbers immediately, they never expire. Lastly, because it’s a worldwide system, your number(s) will be recognized and valid globally.

The ISBN vs. Bar Code: What’s the Difference?

How to get an ISBN number. Step by step instructions for authors looking for information on how to get an ISBN number.Every book needs a unique ISBN, and to be sold, a book needs a separate bar code. The ISBN identifies the book by title, author, genre, its properties, and the location of the publisher. A bar code is completely different and is used for retail and inventory purposes.

Different from ISBNs, bar codes include sales information such as the retail price and the currency in which it’s being sold. The ISBN remains the same throughout the life of a book, but the bar code may change. For example, if you increase or decrease the retail price, the book needs a new bar code.

ASINs and Libraries – Some Final Details to Remember

If you’ve received an ASIN from Amazon for your self-published book or audiobook, it is different from the ISBN number for books. You still need an ISBN to do anything other than selling your work as an eBook on Amazon. Getting one also is a sign of professionalism and that you are focused on the business side of publishing your work.

For some authors, it comes as a surprise that most libraries also require ISBNs. But they have similar book identification needs and the ISBN system is well-suited to their need also. Therefore, it’s in your interest as an author to understand how to get an ISBN number and to do it for your printed books, eBooks, and audiobooks.
