Universal Product Codes are used in the United States and Canada on almost everything that is sold by a retail store. UPCs are divided into two different lengths--2-digit codes or 8-digit codes. There are websites and smart phone apps that will allow you to enter a UPC and identify the item to which that code is referring.
Click on the UPC resource link in the resources section of this article.
Enter the UPC into the search section. The search section will be directly to the left of Look Up UPC. Enter the entire 8-digit or 12-digit UPC.
Click on Look Up UPC after you have entered the all the digits. The name, description and country of issue of the product will be displayed.
