# ASINs and ISBNs

Every product on Amazon has an ASIN that uniquely identifies that product. Until recently, the ASIN for print books was the 10-digit version of the book's ISBN. Although 13-digit ISBNs have been the standard since 2007, until recently they were compatible with 10-digit ISBNs. A 13-digit ISBN with a 978 prefix can be converted to a 10-digit ISBN, which Amazon would then use as the book's ASIN.

Kindle books have never used ISBNs as their ASINs, so if the ASIN in an Amazon link was a valid 10-digit ISBN, the link pointed to a print book. From version 2.0, Local Links used this to determine whether an Amazon link was to a print book or something else.

Recently Bowker, the ISBN agency in the US, have started [issuing ISBNs with a 979 prefix](https://www.ingramspark.com/blog/a-quick-guide-to-979-isbns). These cannot be converted to 10-digit ISBNs, so if a print book has a 13-digit ISBN starting with 979, Amazon assigns it an ASIN that is not based on the ISBN. This means that Local Links can't always tell whether an Amazon link points to a print book or a Kindle book.

For most Amazon stores, this doesn't matter. But some Amazon stores \([Amazon Singapore](https://www.amazon.sg/) for example\) sell print books but not Kindle books.

In versions 2.0 to 3.5, if an Amazon link was to a Kindle book and the user's local Amazon store did not sell Kindle books, the user was directed to [Amazon.com](https://www.amazon.com). If the link was to a print book, the user would be directed to their local Amazon store.

From version 4.0, the user will always be directed to their local Amazon store, since as 979-prefix ISBNs become more and more common it gets increasingly difficult to determine whether an Amazon link points to a Kindle or print book.
