Okay, I've been seeing more questions pop up about ISBNs. Many people think they must buy one before publishing a book, but that isn't always true.
Here's a simple breakdown:
📚 You probably DON'T need to buy an ISBN if:
✅ You're publishing only on Amazon KDP
✅ You are okay with Amazon showing as the publisher
✅ You're testing a book idea before investing more money
✅ You're creating low-content books, journals, or books under a pen name where publisher branding isn't important
Amazon will actually give you a FREE ISBN for paperbacks and hardcovers.
Now here is when buying your own ISBN may make more sense:
💡 Consider buying your own ISBN if:
✅ You want to publish your book beyond Amazon (Barnes & Noble, bookstores, IngramSpark, libraries, etc.)
✅ You want YOUR name or publishing company listed as the publisher instead of Amazon
✅ You're building a long-term publishing brand
✅ You plan to expand into multiple distribution channels
One thing many people don't realize:
❌ One ISBN does NOT cover everything.
Each format typically needs its own ISBN:
• Paperback = 1 ISBN
• Hardcover = 1 ISBN
• Ebook = usually not required on KDP
For beginners, I usually suggest keeping costs low and using the free KDP ISBN while learning the process. You can always invest more as your publishing business grows.
Question for you: Did you buy your own ISBN, or did you use the free KDP option?
