What is a Kindle Book ASIN?
Why do you need an ASIN?
An ASIN, which stands for Amazon Standard Identification Number, is a unique 10-digit code that Amazon assigns to all products for sale on its site. Each ASIN is a unique identifier that Amazon uses internally to track inventory, sales, rankings, make recommendations for other products and much more. If you sell your book or anything else on Amazon, your product has already been assigned an ASIN. This brief guide will explain ASINs for authors.
1) Kindle Book ASIN in the URL
You can find your book’s ASIN by going to your book’s detail page on Amazon and looking at the URL in your web browser. Your Kindle book ASIN appears in the book’s detail page URL on Amazon and it begins with B00 or B01.
https://www.amazon.com/…/dp/B00XXXXXXXX/…2) Physical Book ASIN (paperback or hard cover)
Your physical book ASIN also appears in the book’s detail page URL on Amazon and it is a 10 or 13-digit string of numbers. For physical books Amazon uses your book’s ISBN number as the ASIN.
https://www.amazon.com/…/dp/0123456789/… ← ISBN-10 as ASIN https://www.amazon.com/…/dp/9780123456789/… ← ISBN-13 as ASIN3) ASIN in the Product Details Section
You can also find your ASIN if you scroll down your book’s detail page. For Kindle and physical books, as well as all other products, simply scroll down to the Product details section. You will find the ASIN mid-way through the product detail listings.
