Barcode/ASIN on boxes

Amazon is a forever-growing online marketplace with over 350 million products for shoppers to choose from. But how can anyone identify a single product through the millions in its catalogue? It’s all thanks to the ASIN number.

By using an ASIN , Amazon users can easily track down a specific product they are after instead of wading through a list of items using a general search. Even better, the ASIN number can give you more secret information about a product if you’re using Amazon seller software.

But what exactly is an ASIN number and where can you find it? We’ll answer those question in this guide, along with offering a few tricks on what you can use an ASIN for.

What is an ASIN number?

Amazon Standard Identification Number (ASIN) is a ten-digit alphanumeric unique code that identifies products on Amazon. When sellers create a new product in Amazon’s product catalog, the product is given a unique ASIN number.

This helps Amazon users identify products on Amazon easily. Nearly every product in Amazon’s catalogue has an ASIN number, except for books, which have an International Standard Book Number (ISBN). The number should look like this: “B0BRWYFGYT.”

An ASIN is essential in order to sell a product on Amazon. Sellers can either create a new ASIN or use an existing one when putting up a product to sell.

How to find an ASIN number?

The ASIN of any product can be found on the Amazon product listing page of that product. It is under the Product Information section of the page.

1. On, search for a product you want to know the ASIN number of in the search box.

2. Click on the product.

3. Scroll down to the Product Information section and check the ASIN number.
