MPN = Manufacturers Part Number

ebay need you to put this number in the item specifics, if the item doesn't have one you have to put does not apply

eBay uses an item's brand, manufacturer part number (MPN), and global trade item numbers (GTINs)—such as Universal Product Codes (UPCs) and International Standard Book Numbers (ISBNs)—to help buyers quickly find the items they're looking for.
