The DoD IUID registry provides access to and storage of data of all these properties under the possession of the department. The property under the possession of contractors includes both Contractor Acquired Property and Government Furnished Property. The DoD assigns an IUID to each of these items for the easier maintenance. The IUID has also simplified the methods of keeping tracks of the items.



There are certain rules to guide the assignment and marking of IUID to the property that are under the possession of the contractors.

?In case there is an existing IUID for the property, the contractors are required to use the same IUID for marking and reporting purpose.

?In case the Government Furnished Property provided to the contractors doesn't have a previously established IUID, the contractors must establish an IUID according to the business rules and submit the IUID information to the DoD IUID registry.

?A concatenated IUID should be created for the property using Construct#1, Construct#2, or IUID equivalent recognized by DoD.

?For the incoming Government furnished property, the asset identification number may be used in place of serial number of the item to assign IUID.

?The IUID should include enterprise identifier along with serial number and unique property control number.

?For the items provided to the contractors by the Government for repairing, the Government should mention in the repair contract that the items should be marked with IUID before they are delivered to the Government.

?A virtual IUID is assigned to the property if the property has a unique identification but not physically marked with DoD compliant 2D data matrix symbols. The virtual IUID become permanent when there is necessary of physical marking of the item with a 2D data matrix code.

?While physically marking the property with the 2D data matrix symbols, it is important to note that they comply with the MIL-STD-130 standards. The contractors are required to maintain integrity in case the IUID of the property needs to replace a lost, damaged or destroyed mark with a replacement mark. It should contain the same IUID data elements as the previous one.

?The required IUID marking should be directly applied to the surface of the items or should be securely affixed to the items as identification tag, identification band or identification plate.

?If the items are provided to a contractor in bulk and they are low value items, a single IUID for the total quantity of item can be established. In such cases, prior to the deliver of the items from the contractor's plants to a subcontractor or other location of the contractor, the contractor will conform to the specific procedure of traceability for future use.

?The main contractors are responsible for ensuring that the properties that are under the possession of the subcontractors are recorded in the IUID Registry of the Department of Defense.

As the IUID is the strategic system of the DoD to enhance the traceability of the property, it is the responsibility of the contractors to stick to the guidelines structured by the Department of Defense.
