I get so many questions regarding ISBN’s because it’s a confusing subject. Each book format (print, audio, eBook) needs a different ISBN and I explained why in an earlier post. Some will even argue that a separate ISBN is needed for different eBook formats. This is a gray area.
The most confusing is ISBN vs. ASIN.
I attempt to untangle the difference here.
When you publish on Amazon they give you an option for a free ASIN.
Is an ASIN the same as an ISBN? No!
Is this important? Yes!
Before you publish you need to think about where and how you want to sell your book. Which online and/or brick and mortar options you chose will guide you to the correct search number option you will want to use.
ASIN stands for Amazon Standard Identification Number. This number is a unique block of 10 letters and/or numbers that identify items within Amazon’s system. This number is not a searchable number outside of Amazon. If you plan to sell your print books and eBooks outside of Amazon you will want to use an ISBN for each format because an ISBN is searchable worldwide.
In my opinion, if you are ONLY going to sell your book on Amazon an ASIN is just fine.
