What is a product identifier?

A product identifier is just what it sounds like: it’s a way to clearly identify a product for sale. Product identifiers are usually a series of numbers, or letters and numbers. For product identifiers to be useful and helpful in today’s world, they must be unique, and they must be verifiable, everywhere in the world, forever, and no matter whether the item is for sale online or in physical stores. And that is exactly what the GS1 GTIN™ offers: your GS1 GTIN™ will be different to the billions of GS1 GTIN™ we’ve already issued, recognised by all major retailers, supermarkets and marketplaces around the world and they will be verifiable thanks to Verified by GS1, our global database.
