What is an ASIN and a UPC?

When entering the realm of eCommerce, it isn’t always easy to figure out the various factors at play, especially when it comes to ASIN, UPC, and EAN product identifiers. We’ve put together a brief guide so you can enhance your knowledge and begin to see sales climb.

ASIN stands for Amazon Standard Identification Number and is a product identifier which is used by Amazon. It is ten characters long and includes letters as well as numbers.

The UPC (Universal Product Code), is a 12-digit code which is unique for every product. You can find it in the barcode. As implied by its name, this code is universal.

While both ASIN and UPC help retailers quickly find a specific product, there is a big difference between them. While UPC identifiers work worldwide, Amazon’s ASIN is unique within a particular Amazon marketplace. This means that the ASIN for a given product in the U.S. can be different than that on Amazon U.K.

The role of UPC and ASIN for a seller

Product Identifiers, like UPC and ASIN, help retailers to keep an overview of their stock, track products, and quickly obtain product details. Online sellers also need these identifiers to more efficiently order and move inventory.

When selling on Amazon, your product must have an ASIN to be listed. Without an ASIN, your product will not be searchable, and you will end up with one big sad pile of deadstock. To make matters easier, when you provide the UPC to Amazon, they will automatically add the correct ASIN to your product listing.

Since the UPC is universal, most retailers, like Walmart and Amazon, will need it to identify the item and determine if the same item is sold elsewhere. When selling on eBay, you also need to provide the UPC because it will allow buyers to find products more quickly. Providing the Universal Product Code is crucial as it will improve your product’s placement on eBay and search engines like Google.
