ASIN · Amazon Standard Identification Number
An ASIN (Amazon Standard Identification Number) is the unique 10-character code Amazon assigns to every product in its catalogue.
You'll find an ASIN in a product's URL, just after /dp/, and in the product details section. It points to one specific listing, so it's the handle that almost every research tool uses to pull data about a product.
Each product variation and each marketplace can have its own ASIN.
Why it matters
The ASIN is the key that links a product to its sales rank, reviews, keywords, and competitors, so it's where most research starts.
