Starting on June 29th eBay will make it optional that any new items include the product brand as well as identifiers such as the manufacturer part number (MPN), global trade item number (GTIN), Universal Product Code (UPC) to complete new listings and manual relists. Product identifiers make it even easier for buyers to find and purchase your items.  We have exposed these fields in both the add and edit item pages as well as included them in the Item Specifics section of the eBay listing tool.  You can read the official eBay announcement by visiting this link: eBay Product Identifier Update
