How to Enter a UPC code
Universal Product Codes (UPCs) are 12-digit numbers used to identify products. Find your UPC code on your product's packaging or back cover.
When entering a UPC Code for a listing using Pre-Filled Item Information, be sure to enter the entire number at the bottom of the bar code, including the smaller numbers on the left and right hand sides.
In many cases, eBay only has access to the information relating to the latest version of the product. Older versions or editions may have different UPCs. As a result, you may be unable to find an item by UPC.As always, you can list any item the ordinary way, without using Pre-Filled Item Information.
