Item Unique IDentification (IUID) is an asset identification system generated by the United States Department of Defense (DoD). IUID compliance requires all tangible items, including assets and personal property owned by the DoD, to be marked with a unique serialized identification number (UID). IT became effective January 1, 2004 for legacy and newly requisitioned government furnished property (GFP), with the goal of placing 100% of GFP in the new UID Registry. The markings should be applied directly to the surface of the item or shall be applied to an identification plate, tag or label securely fastened to the item. The UII is intended to be a permanent mark and cannot be changed over the life of the item.
The purpose of the UID mandate is to achieve visibility of all assets for continuous reporting to the military’s Wide Area Work Flow (WAWF) system. It’s goal is to enable better management of components of complex DoD systems over their complete life cycle, ensuring that all maintenance, transportation and supply-related processes are captured electronically in order to provide intelligent data for knowledge-enabled logistics. The collected data will also satisfy GAO requirements for cost containment and spending accountability. IUID standards affect DoD contractors and suppliers, requiring them to mark and track government deliverables and property and report their data frequently to maintain IUID compliance. The markings should be applied directly to the surface of the item or shall be applied to an identification plate, tag or label securely fastened to the item and is intended to be a permanent mark that cannot be changed over the life of the item.
