Amazon Standard Identification Number

Amazon Standard Identification Number (ASIN) is a unique code given to every item on Amazon.com. It's like a product's address. That way, Amazon knows what product you're talking about when you order something or look at a product page. An ASIN looks like this: B018F07SI2. So, next time you're on Amazon, check the ASIN of your product to make sure it's the one you're looking for!
