GS1 Global Individual Asset Identifier

GIAI is a globally unique identifier for individual assets — production machinery, vehicles, IT equipment, instruments, returnable transport items. The GIAI persists across the asset's operating lifetime and is the primary handle for asset-level lifecycle events (maintenance, retrofit, decommission) recorded in DTEs.
