Serial number

A serial number is a unique identifier for an individual product, component or object within a series. It is important for traceability because it allows identical items to be distinguished not only as a group but as individual units. This makes it possible to track when a unit was manufactured, moved, inspected or processed. In automated identification systems, the serial number is often stored on an RFID tag or within the Electronic Product Code and linked with process data. This allows each tagged object to be identified clearly and assigned to a specific history. The serial number provides the basis for tracing individual workpieces, containers or products reliably throughout the entire process.
