What Is an ASIN and Why It Matters for Sellers

An ASIN (Amazon Standard Identification Number) is the unique 10-character ID Amazon assigns to every product. It is the backbone of product research.

What an ASIN looks like

Modern ASINs start with "B0" followed by eight characters, e.g. B08N5WRWNW. You can find it in the product URL after /dp/.

Why ASINs matter

• They uniquely identify a product across tools and marketplaces.
• Reselling tools import products by ASIN.
• Product research means building and filtering ASIN lists.
