How to convert ISBNs
Use the bulk ISBN converter tool to convert ISBNs in bulk. You can enter multiple ISBN-10, ISBN-13, ASIN, EAN, or UPC codes, and they'll be automatically converted to the appropriate formats.
Conversion Options
- Convert ISBN-13 to ISBN-10
- Convert ISBN-10 to ISBN-13
- Convert UPC to EAN
- Convert ISBN-13 to ASIN
How to Use
Enter your ISBNs, separated by spaces, tabs, or commas. The tool will ignore any non-ISBN text.
Example
9780735211292, non-isbn text is ignored, 0735211292
After conversion, the updated ISBNs will appear in the same text area, replacing the original values inline.
ASIN Conversion Details
Our tools can convert ISBN-13s to ASINs. However, please be aware of the following:
- Reliability: ASIN conversion relies on data from Amazon, which may not always be 100% accurate or up-to-date.
- New ISBNs: When a new ISBN is released, it can take some time for its corresponding ASIN to be populated in Amazon's systems and, consequently, in our conversion tool. You might experience delays or an inability to convert some ISBNs to ASINs.
We strive to provide the most accurate ASIN conversions possible, but these factors are outside of our direct control.
What is the difference between an ASIN and an ISBN-10? While both are 10-character identifiers, an ASIN (Amazon Standard Identification Number) is Amazon's proprietary system for identifying products within its marketplace. An ISBN-10 (International Standard Book Number) is a globally recognized identifier specifically for books. If a book has an ISBN-10, that ISBN-10 is also its ASIN on Amazon; this conversion is direct and reliable. However, not all ASINs are ISBN-10s (e.g., for products other than books), and many books on Amazon (especially those published after 2007 or Kindle-exclusive versions) will have an ASIN that is different from their ISBN-13 and will not have an ISBN-10. These non ISBN based ASINs are where we have to use other methods to convert the ISBN-13 to ASIN which are not 100% reliable.
