Amazon Standard Identification Number

An Amazon Standard Identification Number (ASIN) is a 10-character alphanumeric unique identifier assigned by and its partners for product identification within the Amazon organization.[1] They were originated in 1996 by Rebecca Allen, an Amazon software engineer, when it became clear that Amazon was going to sell products other than books. The 10-character format of the ASIN was adopted so that Amazon databases and software, which were designed to expect a 10-character ISBN field, would not have to be changed to accommodate the new identification format.[2]

Usage and structure

Each product sold on is given a unique ASIN. For books with a 10-digit International Standard Book Number (ISBN), the ASIN and the ISBN are the same.[3] 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. The ASIN forms part of the URL of a product detail page on Amazon's website.[4]

If one knows the ASIN of any product on Amazon, one can access its Amazon page easily by appending it (adding it to the very end) of the following URL:[ASIN]

Note that the above is not a valid URL; a correct ASIN must be inserted at the location of the [ASIN] placeholder.
