Warehouse reference · Inventory & traceability
Serial number control
A serial number identifies an individual unit within an agreed identification scheme. Serial tracking differs from lot tracking because the unit-level relationship must be preserved. Processes vary in when serials are captured and verified.
How it works in practice
Define serial uniqueness and the events requiring capture: receipt, packing, shipment, return, or other transitions. Validate that recorded serials belong to the correct item and quantity and that duplicates are handled deliberately.
A warehouse example
A shipment of five serialized units needs five valid unit identities when the process requires outbound serial capture. A quantity confirmation alone does not establish which units left.
Illustrative scenario, not a claim about a client engagement.
What to watch for
Scanning a serial at one stage does not ensure it remains linked through repacking or substitution. Test the relationship across the full workflow, including returns.
A useful question
What happens if the scanned unit’s serial is already associated with another shipment?
