GS1 Global Traceability Standard (GTS2) introduces two key concepts for interoperable
traceability: 1) Critical Tracking Events (CTEs), these are the actual events, such as receiving,
packing, shipping, transporting, that occur to the traceable object during its lifecycle, and 2)
Key Data Elements (KDEs), these are the elements of data that describe the actual instances
of the CTEs.
GS1 identification standards Global Trade Item Number® (GTIN) and Global Location Number
(GLN) uniquely identify the objects that are moving throughout supply chains and the
locations to which and from which they travel. Identification keys enable the connection of
physical and information flows within a trading partner’s processes as well as across different
trading partners’ processes.
Barcodes and EPC/RFID, data capture standards, along with data sharing standards the
Global Data Synchronisation Network® and EPCIS (Electronic Product Code Information
Services) enable automated processing and sharing of information between and across
trading partners. EPCIS is a critical component for traceability systems. EPCIS enables
trading partners to share information about the physical movement and status of products
across supply chains.
GS1 provides sector-specific traceability standards that enable traceability across and within
industry sectors. Explore our standards for traceability in Healthcare, Retail and Rail.
