Why Every Book Needs a Barcode
Whether you’re publishing a paperback, hardcover, eBook, or audiobook, barcodes are a crucial part of the publishing process. They make your book trackable, sellable, and professional—allowing bookstores, libraries, and online retailers to identify and catalog your work.
Two of the most common identifiers are ISBN and ASIN. While they may seem similar, they serve different purposes, and as an author you need to know the difference.
What is an ISBN?
ISBN (International Standard Book Number) is a unique identifier for books. It’s required for most publishing formats and is used by bookstores, distributors, and libraries worldwide.
- Each format of your book needs its own ISBN (print, eBook, audiobook, etc.).
- ISBNs also come with barcodes, which are printed on the back cover of physical books.
- Without an ISBN, you cannot publish professionally outside of Amazon, and your book will not be stocked in stores or catalogs.
👉 ISBNs are not free. They must be purchased, and pricing varies depending on whether you’re publishing a single book or a series. At Books N Ink Publishing, we help authors secure ISBNs and barcodes quickly and correctly—so your publishing process is seamless.
What is an ASIN?
ASIN (Amazon Standard Identification Number) is Amazon’s internal tracking code for products—including books.
- Every book published on Amazon automatically gets an ASIN.
- ASINs are free and come as part of the publishing process.
- They are used only within Amazon’s system to list and track your book.
- ASINs are not a substitute for ISBNs if you want worldwide distribution.
In other words: if you’re publishing only on Amazon, your book will still have an ASIN. But if you want your book in bookstores, libraries, and global platforms, you’ll need an ISBN as well.
ISBN vs ASIN: The Key Difference
- ISBN = Universal book identifier, purchased separately, required for bookstores, distributors, and professional publishing.
- ASIN = Amazon’s free identifier, automatically assigned when publishing on Amazon.
📌 Think of it this way:
- ASIN = Amazon’s “ID card” for your book.
- ISBN = The passport that lets your book travel worldwide.
Do You Need Both?
Yes—if your goal is to reach the widest audience possible.
- If you’re publishing only on Amazon Kindle, your ASIN is enough.
- If you want to publish in print, libraries, bookstores, or internationally, you must have an ISBN.
