Unique Identification (UID) is often associated with defence and aerospace programmes, but the underlying need arises in many types of system deliveries. UID becomes relevant when individual identification of products or components is formally required, for example through customer specifications, contractual obligations, or regulatory frameworks.
In a typical UID implementation, each relevant item is assigned a unique identifier that remains stable throughout the product’s lifecycle. This identifier is physically marked on the product and represented in machine-readable form, often using DataMatrix codes. The purpose is to ensure unambiguous identification across documentation, logistics, maintenance, and configuration control.
The challenge is rarely the marking itself, but rather how UID is integrated into existing processes. Questions often arise around what level of the product structure should be identified, how identifiers are generated and managed, and how data quality is ensured over time. A controlled approach to UID focuses on interpreting requirements, selecting appropriate marking methods, and ensuring that the implementation is both compliant and practically usable in daily operations.
