The GS1 system

The GS1 standards are designed to help you identify, capture, share and use information – wherever you are in the world. Our standards are the global language of business, supporting real-world supply chain business processes.

The standards



Identification numbers

In the GS1 System, numbers are used to identify anything from products to invoices and warehouses. They make it easier to identify, track and share data in your supply chain.
