Logistics traceability is the capability to track the location, status, and custody of goods or parcels at every stage of their journey through a supply or distribution network. It provides a complete, auditable record of each event from origin to final delivery, enabling visibility, accountability, and rapid incident resolution. In regulated industries such as pharmaceuticals and food, traceability is a compliance requirement under GxP standards and EU regulations. Smart locker systems contribute directly to traceability by recording every parcel interaction with a timestamped digital log. Columat provides end-to-end traceability for all parcels and assets managed through its smart locker network. Related concepts include GxP compliance and parcel management.
