From Wikipedia, the free encyclopedia.
The Amazon Standard Identification Number (ASIN) is a product identification number used by Amazon.com.
Each item in Amazon.com is given a unique ASIN number. For books that have an ISBN, the ASIN and the ISBN are the same. Books without an ISBN and other materials are also given an ASIN by Amazon.
