While over 90% of book sales move through Amazon book sales, there’s a hitch that many first-time authors and newbie writers are unaware of - the limitations of using an Amazon ISBN number for your self-published book.
Because a “free” ISBN can be a significant incentive for using an Amazon ISBN, you should know that you’re severely limiting yourself on how and where you can sell your book when you use an Amazon ISBN.
What is an ISBN Number?
An ISBN is a unique 13-digit number that most published books have assigned to them. Usually, an ISBN number in the United States typically starts with 978 or 979. Your ISBN number for your book identifies various attributes about a book, such as a book edition, publisher name, page count, and other elements of a published book.
