Providing DoD with improved readiness, asset visibility, life cycle item management, and accountability

Item Unique Identification (IUID)

WHAT IS IUID?

IUID or Item Unique Identification, is a system of marking items delivered to the Department of Defense (DoD) with unique item identifiers UIIs), that distinguish the items from all other like and unine items. The data from which the UIIs are derived is encoded in machine-readable data matrix symbols and the UIIs are employed in life-cycle management of the items.


WHY USE IUID?

The UII serves as a primary data key to access information about the item across DoD business systems. Encoding the data in a data matrix symbol enables an error-free, automated data transfer capability, eliminating issues inherent in manually-entered data. Army serialized item management (SIM) policy mandates that items designated for SIM within the Army be marked with IUID.


HOW DOES IUID WORK?

Item Unique Identification (IUID) tag
  • Acquiring activities contractually designate items requiring IUID, based on criteria codified in DoD and Army policies.
  • Suppliers assign each of the items designated for IUID a UII and encode the data from which the UII is derived in a data matrix mark on the item.
  • The supplier enters that data and additional pedigree data into the Receiving Report module of Wide Area Workflow (WAWF).
  • When the item receives government acceptance, the WAWF data flows automatically to the DoD IUID Registry.
  • Upon receipt, the Army uses the item marks and UIIs to automate management of the IUID-marked item, using bar code imagers to transfer data encoded in the data matrix to Army automated systems.
  • AMIS helps Army customers deal with the details of IUID.
