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.

Around the world, GS1 works with industry to maintain and create the GS1 standards.
The GS1 system is a set of standards for the unique identification of all trade items, services, logistic units, consignments, assets, documents, relationships, parties and locations at every point in the supply chain.
GS1 and ISO share the same values and the same beliefs in the vital importance of neutral, voluntary, consensus-based, market-relevant global standards.
