Definition & Meaning of "asin"

What is an "ASIN"?

An ASIN, or Amazon Standard Identification Number, is a unique identifier used by Amazon to catalog and track products sold on its platform. Each ASIN is a 10-character code made up of letters and numbers that helps Amazon and its users quickly find specific products. Unlike ISBNs, which are used for books and other publications, ASINs can be assigned to any type of product, including electronics, clothing, and more. The ASIN is used within Amazon's system to manage inventory, process orders, and facilitate searches on the site.
