The acronym ASIN stands for Amazon Standard Identification Number, that is, the standard Amazon identification number. It is a unique alphanumeric code (numbers and letters) that each product has within the Amazon portal in order to identify it correctly.
Each ASIN is unique and is always associated with a single product or a variation of it. It is a basic requirement without which no product can be activated on Amazon. In the case of books, the ASIN exactly matches the ISBN.
Amazon Standard Identification Numbers (ASIN) are unique blocks of 10 letters and/or numbers that identify a particular product. The ASIN can be found on the product information page in Amazon.com. For books, the ASIN is the same as the ISBN, but for all other products a new ASIN is created when the item is uploaded to the Amazon catalog. You will find an item’s ASIN on the product detail page along with more related item details, which may include information such as size, weight, and etc.
ASIN barcodes can be used to search for items in the Amazon catalog. If you have the ASIN of the product, you can search in the search box (which is located at the top of the Amazon pages), press the “Go” button, and if the item appears in the catalog list, it will appear in the search results.
