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?
