ISBN Numbers: 9 Mistakes to Avoid When Making Your Purchase

Are you planning to self-publish or release your next book? If so, securing an ISBN is a critical step you can't overlook. But while buying one seems straightforward, it’s easy to stumble into mistakes that could cost you time, money, or even control over your book's identity.

Have you wondered why some books have multiple ISBNs? Or why do some authors regret choosing the wrong provider? Knowing the answers to these questions is crucial for making informed decisions. When it comes to an ISBN number purchase, understanding the potential pitfalls can save you from unnecessary headaches.

To help you navigate this process smoothly, we’ve outlined nine common mistakes people make when purchasing ISBNs—and how to avoid them.

1. Failing to Purchase ISBNs from the Right Source

Purchasing an ISBN from unofficial or less reputable vendors can lead to counterfeit numbers or unreliable support. It is essential to buy ISBNs from trusted sources, such as the International ISBN Agency or your country’s ISBN agency, to ensure the authenticity and proper management of your book's identifier.

2. Not Understanding the Number of ISBNs Needed

Many authors purchase a single ISBN, assuming it covers all formats of their book. However, different formats—such as print, digital, or audiobooks—require separate ISBNs to avoid confusion during distribution.

3. Failing to Match ISBN to Publication Format

Using the same ISBN for multiple formats, such as print and eBook, can cause confusion for readers and distributors. Each format of your book requires a unique ISBN to ensure accurate identification.

4. Overlooking the Importance of Ownership

ISBNs tied to publishing platforms may not grant full ownership rights, limiting your control over future publishing or distribution. It’s crucial to retain full ownership to have the flexibility to use your ISBN as needed.

5. Using ISBNs Tied to Publishing Platforms

ISBNs purchased through online publishing services might come with restrictions, making it difficult to switch platforms or manage your book independently. By opting for ISBNs, you can fully control and prevent being locked into one service.

6. Not Paying Attention to ISBN Pricing

Cheaper ISBN options might lack essential features or reliable support. Researching different ISBN packages and their pricing helps ensure you get what you need without sacrificing valuable services.

7. Failing to Update Information When Necessary

Metadata linked to ISBNs must remain accurate. Outdated or incorrect information can cause misidentification of your book, leading to issues with distribution and sales.

8. Not Preparing for Multiple Distribution Needs

ISBNs are geographical identifiers, and failing to plan for future distribution channels can lead to complications. Books distributed in different regions or formats may require additional ISBNs.

9. Overlooking ISBN-Associated Fees

Some ISBNs may come with ongoing maintenance fees or other charges. Failing to account for these additional costs could impact your budget and publishing strategy.

Conclusion

Purchasing an ISBN number is a crucial decision for authors, but it comes with its fair share of challenges. Avoiding common mistakes—such as purchasing from unreliable sources, mismanaging format pairings, or neglecting ISBN-related costs—will help ensure a smoother publishing process. By staying informed and mindful, you can navigate the ISBN purchase confidently and set your book up for success.
