Serial number tracking

What is serial number tracking?

Serial number tracking is a tracking method that uses unique identifiers to trace and monitor individual items.

Rather than being grouped by batch, each unit is treated as a distinct entity. Important information such as attribute data and movement history can therefore be recorded at a more granular level.

Serial number tracking in the supply chain

Serial number tracking offers complete traceability from manufacturing through to customer delivery. It supports:

  • Warranty management

  • Quality control

  • Theft prevention

  • Regulatory compliance

Certain industries—for example, electronics, medical devices and pharmaceuticals—rely on serialized inventory systems to meet compliance requirements and manage product lifecycles.

Serial number tracking and inventory management

Serial number tracking plays an important role in warehouse inventory management:

  • Operators enter manufacturer-assigned serial numbers into the warehouse management system (WMS)

  • The system then creates individual records for each unit

  • When units are moved between locations, the system updates records in real time

  • The unit is scanned during picking and shipping

  • The WMS creates an audit trail showing which serial numbers fulfilled which orders

Benefits of serial number tracking

Warranty management

Serial number tracking simplifies the warranty management process. Each item's purchase date, previous repairs and warranty expiration information can be verified instantly, preventing fraudulent claims.

Recall efficiency

Serial number traceability allows manufacturers to recall specific items rather than entire production runs. This minimizes disruption and costs without compromising safety.

Theft prevention

The WMS documents each unit's movements and handlers using serial numbers. This chain of custody helps to deter internal theft and supports investigations when inventory discrepancies arise.
