• Identify

    GS1 standards begin with GS1 Identification Numbers, used to uniquely distinguish all products, logistics units, locations, assets and relationships across the supply chain from manufacturer to consumer. GS1 Identification Numbers provide the link between an item and information about it.They are the foundation for all GS1 standards. As the global supply chain has evolved, GS1 Identification Numbers have extended to include assets, documents and more to keep pace with business developments.The 11 GS1 Identification Numbers include: GTINs for products, SSCCs for shipping containers, GIAIs and GRAIs for assets, GLNs for company and location identification, and GDTIs for documents.


GS1 Data Carriers for automatic identification and data capture (AIDC) are capable of holding varying amounts of data for different business processes and trading requirements. The data encoded in GS1 Data Carriers not only uniquely identifies products at every level of packaging, it provides access to product information and visibility of product movement through the supply chain.The 9 GS1 Data Carrier families include: EAN, UPC, ITF-14, GS1-128, GS1 Databar, GS1 QR Code and GS1 Data Matrix barcodes, as well as standards for EPC-enabled HF and UHF RFID tags.
