GS1 Source is a framework for sharing standardized product information digitally. It was developed in response to the growing need for brands and retailers to communicate accurate product data to online consumers. GS1 Source works by having brand owners provide standardized data to certified third-party aggregators, who then make the information available to application developers and consumers. The system aims to overcome challenges around inconsistent and low-quality product data online. GS1 Source uses established GS1 standards and provides a scalable and interoperable way for all stakeholders in the supply chain to access and exchange critical product information in the digital marketplace.
