GS1 Standards

The Global Language of Business

GS1 Standards provide a common language and help to create seamless work processes that allow businesses to identify, capture, and share information the same way all over the world.

Through the power of GS1 Standards, organizations can use accurate, robust information that makes it possible for the right product to be in the right place at the right time as well as allow consumers to find the products they are looking for.

Think of GS1 Standards as a product’s data “DNA”—the building block for connecting an item with all the information about it. From that foundation, small to large companies are building even better ways to do business. For instance, GS1 Standards enable:

  • Consumers to follow the food they eat—from the farm to the table
  • A shopper to access detailed product information from their mobile device
  • Companies to save through greater product and item visibility in their supply chain
