Define electronic-product serial-number rules: issue source, assembly association, readable data, manufacturing records, duplicates, failed marks and rework.
Define the serial-number source, required format and the event that associates the number with an assembly. Record where the identifier is applied or read and which manufacturing results must remain linked to it. Set explicit decisions for duplicate numbers, failed marking, rework and replacement labels so the physical product and record do not become ambiguous.
Connect the issue-to-record process with the serial-identification brief. Keep readable data, correct assembly association and record reconciliation as distinct acceptance questions.
Plan serial identification of electronic products around your identifiers, substrates, production events, system interfaces, exceptions and verification records. Discuss a practical data-flow approach with Oxford Traceability. Use this guide to resolve identifier and data rules for serial identification of electronic products before it limits the final system.

Record the number-issuing source, actual identifier examples, required format and association event for the assembly. Identify mark/label location, read points and the manufacturing information retained through assembly and testing.
Include representative assemblies, normal and difficult substrate/presentation conditions and the production events at each handover. Add actual duplicate, failed-mark, rework and replacement-label examples to the trial set.
Map each exception to a controlled action and responsible owner. Check that the physical assembly keeps the intended serial identity and that agreed manufacturing records remain associated and reconciled. Retain unresolved decisions separately from demonstrated results.
Define where serial numbers are issued, the required format and the event that associates a number with an electronic assembly. Identify the authoritative information source and the production records that must retain that association.
Provide representative assemblies and proposed mark or label locations, including difficult surfaces and access. Trial the actual readable data and its presentation using the proposed method; a readable sample does not establish that the number belongs to the correct assembly.
Describe the production pattern and where the identifier must be read during assembly and testing. Include normal and difficult presentation, available access and the point at which the result is checked against the intended production record.
Map the events from issuing a serial number to marking, reading and retaining manufacturing results. Identify which system or person owns each decision and how the physical assembly is kept associated with its record at each handover.
Challenge duplicate numbers, rework, failed marking and replacement labels. Agree the controlled response for each case, including how the identity of an existing assembly is preserved and how conflicting physical identifiers are avoided.
Retain the issued serial, the assembly association and the agreed marking/read and manufacturing records. Check readable data separately from record correctness and reconciliation; let the responsible organisation define retention and access rules.
