What is ASIN?

ASIN stands for Amazon Standard Identification Number.

An ASIN is the 10-character ID Amazon assigns to each product in its catalog (for example B0XXXXXXXX). One product page = one ASIN.

Example

When you create a new product on Amazon it gets an ASIN; other sellers of the same item list under that ASIN.

Why it matters

You need the ASIN to look up a product, run ads on it or check its performance.
