Identification Marking Process


Unique Identification (UID) and Item Unique Identification (IUID) are part of the identification marking process mandated by the United States Department of Defense (DoD). The U.S. Government calls for unique and specific numbers to be assigned to all government-owned and government-purchased tangible equipment, in accordance with established rules and guidelines as set forth by MIL-STD-130.
The UID compliant marking must be applied to the asset or directly marked on the asset for its lifecycle through the use of two-dimensional (2D) Data Matrix ECC 200 Symbols. UID and IUID marking is required for all military property and equipment with an acquisition cost over $5,000, equipment that is mission essential, controlled inventory, or serially-controlled. The number associated with UID marking is the unique item identifier, or UII, which is designed to be globally unique.
