Usage and structure[edit]

Although ASINs used to be unique worldwide, global expansion has changed things so that ASINs are only guaranteed unique within a marketplace.["citation needed] The same product may be referred to by several ASINs though, and different national sites may use a different ASIN for the same product.["citation needed] In general, ASINs are likely to be different between the country sites unless they are for a class of product where the ASIN is based on an externally defined and internationally consistent identifier, such as "ISBN for books.["citation needed]

Each product sold on is given a unique ASIN. For books with 10-digit "International Standard Book Number (ISBN), the ASIN and the ISBN are the same.[2] The "Kindle edition of a book will not use its ISBN as the ASIN, although the electronic version of a book may have its own ISBN. In most cases, it is possible to convert an ASIN to obtain a corresponding "EAN code.["citation needed]

ASINs are also used for other items used by (and subsidiaries), such as businesses in the yellow pages (on " and "OpenSearch feeds.["citation needed]
