Product identifiers

With 134m active buyers shopping on eBay, there are huge opportunities for you to take advantage of our buyer data. We are constantly monitoring buyer browsing behaviour to see how they search for products and use eBay filters to find what they are looking for. We are using this data to help you list your items in a way that will help them be found faster and increase the chances of making more sales.

Product identifiers are essentially unique codes that can be used to identify a specific product. They work like barcodes and include: European Article Numbers (EANs), International Standard Book Numbers (ISBNs) and Manufacturer Part Number (MPN).
