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 Amazon.com 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.
