Why is the GS1 Global Registry useful?
The GS1 Global Registry serves as the single point of truth by serving as the central repository for catalogue items and parties and for facilitating the publication and subscription of product and location information. Broad scale interoperability is not achievable without a Global Registry. Catalogue Item Uniqueness: The GS1 Global Registry efficiently guarantees the uniqueness of the catalogue item (GTIN + GLN + target market) for a particular data source.
