ASIN
ASIN stands for Amazon Standard Identification Number. It is a unique identifier assigned to each product on Amazon. ASINs are used to track products, identify them in search results, and create product listings.
UPC
UPC stands for Universal Product Code. It is a 12-digit barcode used to identify products in the United States and Canada. UPCs are required for selling products on Amazon.
EAN
EAN stands for European Article Number. It is a 13-digit barcode used to identify products in Europe and other parts of the world. EANs are also accepted on Amazon.
The main difference between ASINs and UPCs/EANs is that ASINs are specific to Amazon, while UPCs/EANs can be used in any store that sells products with barcodes. Another difference is that ASINs are 10 characters long, while UPCs/EANs are 12/13 characters long.

Why Do You Need to Convert UPC to ASIN?
Amazon sellers doing online arbitrage, wholesale sellers, and dropshippers who make money on the price difference of the products from different suppliers must be able to convert UPCs or EANs to ASINs. Here’s why that is necessary.
Product matching
You must be able to match products on Amazon and other websites. UPCs and EANs are unique identifiers for products, but they are not always displayed on Amazon product pages. By converting the UPC to an ASIN, sellers can quickly and easily identify the product on Amazon.
Example. An online arbitrage seller finds a product on a retail website that is listed at a lower price than it is selling for on Amazon. To see if the product is a profitable deal, the seller must convert a UPC to ASIN to look up the product on Amazon and check the sales and performance data. If the seller determines the product is profitable, they can purchase it from the retail website and list it on Amazon for a higher price.
Profitability estimation
You must estimate if a product is a profitable deal. Amazon provides sellers with information about the product’s Best Sellers Rank, ratings, and other product performance metrics, but this data is only available for products with ASINs. By converting the UPC or EAN to an ASIN, sellers can get a better idea of how well a product is selling and whether it is likely to be profitable.
Example. A wholesale seller gets a list from a supplier with 1000 products. The supplier provides the seller with the UPCs for the products. The wholesale seller must search the Amazon ASINs that match UPCs or EANs and find their product listings. They compare the product average Buy Box prices to the wholesale prices of the products they get from the supplier. They sort out the products having a lower wholesale price than the average selling price on Amazon. These products are the candidates for profitable deals.
