Adding UPCs, EANs, and ISBNs for Your Products


Most categories require sellers to use a product identifier to create new product pages and offer listings on the website. The most common identifier used by sellers is a UPC.

If you don’t provide a UPC, EAN, or ISBN, you will generally receive an error message. When this occurs, you will need to add the product’s identifier in order to create a new product detail page in the catalog or complete your inventory offering. (If you don’t have a UPC, EAN, or ISBN for your product, see How to Obtain a Product Code.)

The UPC field is supported in the Add a Product tool and in Inventory File templates.

Add a Product

The Add a Product tool will allow you to create new product detail pages and offerings one at a time. If you search for a product and find it in our catalog, the UPC, EAN, or ISBN will be automatically entered for you and you can continue to create your offering. If you create a new product detail page, you can enter the UPC or EAN on the “Add This Product to Our Catalog” page after completing the product classification step.

What’s the difference between UPCs and EANs?


UPCs were invented in the 70’s by George Laurer while working for IBM. The first item scanned using UPC technology was a ten pack of juicy fruit gum on June 26, 1974 for 67 cents. Since then, millions of items have been using UPCs throughout North America, the United Kingdom, Australia, and New Zealand.

UPC’s consist of twelve digits and EANs (European Article Numbers) use thirteen numbers. While both systems identify a product to their manufacturers, the EAN’s extra digit reveals the manufacturer’s locale. While initially used in Europe, EANs are now recognized internationally and have been renamed to International Article Number. When you order from you get both a UPC and an EAN number enabling you to sell your products globally! Sites like Amazon will accept both UPCs and EANs.
