Amazon Standard Identification Number (ASIN) is a ten-digit alphanumeric code that identifies products on Amazon. It’s unique for each product and is assigned when you create a new product in Amazon’s catalog. Almost every product on Amazon has an ASIN except books (they use the ISBN or International Standard Book Number in place of an ASIN). Getting this Amazon identifier for your products is necessary before you can sell them on Amazon. While many use the Amazon scraping tool to extract data, it does not give the best result.
For any single product sold on Amazon, there should only be one ASIN and one product detail page. This makes it easier for customers to navigate Amazon’s massive catalog. Any duplicate products and their ASINs are eventually merged. Before you sell an item on Amazon, check if an ASIN already exists for that product. If there is one, you can start trading by creating an offer under that ASIN. When you do this, you share the ASIN with every other seller offering the same product. This is generally the case for resellers, retailers, and products with wide distribution.
