Item Unique Identification is a system of establishing globally ubiquitous unique identifiers within the Department of Defense, which serves to distinguish a discrete entity or relationship from other like and unlike entities or relationships. Tangible items are marked with a unique identifier in the form of a character string, number or sequence of bits assigned to a discrete entity or its associated attribute which serves to uniquely distinguish it from other like and unlike entities. Each unique identifier has only one occurrence within its defined scope of use.
IUID is physically marked on tangible assets using a 2D data matrix in the format of ISO 15434.
