What is an ASIN?

ASINs are Amazon's unique identification number for products (Amazon Standard Identification Number). It is a 10-character alphanumeric (so just numbers and letters from A to Z) code that is assigned to each and every product listed on Amazon.

Why do I need an ASIN?

If you are a wholesaler, then you need to know the ASIN(s) for the products you sell. This allows you to list the product you have for sale, ultimately, make money! However, finding these ASINs, particularly if you have a lot of products, can be time consuming. That's where a bulk ASIN lookup tool, like Rocket Source comes in. You can simply upload a list of your UPC codes and get back a list of ASINs.

Features of a good UPC to ASIN converter

Accuracy and reliability are important factors in finding a good lookup tool. But, you need more than just that. You need a tool that moves as fast as you do and can process your supplier files quickly, helping you to find profitable products to sell before your competitors.

Compatibility with different types of product codes (such as EANs or ISBNs) is also crucial, depending on the types of products you sell.
