Tangible items are distinguished from one another by the assignment of a unique identifier in the form of a unique data string and encoded in a bar code placed on the item. An item unique identifier is only assigned to a single item and is never reused. Once assigned to an item, the IUID is never changed even if the item is modified or re-engineered. IUID is similar to social security numbering used to distinguish citizens of the United States from one another.
In the case of a lot or batch of items that are not individually serialized, the entire lot or batch may have a unique identifier assigned. For example, a manufacturer might place a unique IUID physical mark on the exterior of a kit or container that holds a gross quantity of mission critical items. The government would refer to this IUID at the point of acceptance. The entire gross quantity in this case is treated as a single item. In this case, the IUID is no longer useful after the items are separated, and the individual items from the batch or lot are never uniquely identified.
IUID is physically marked on tangible items or assets using a two-dimensional (2D) Data Matrix symbol with the data formatted in accordance with specified standards. The encoded data is identified by the use of data identifiers, application identifiers or text element identifiers. The choice of which identifier to use is based upon normal industry practices of the organization assigning the serialization. The formatted data is called a Unique Item Identifier (UII). The Data Matrix symbol is a machine-readable representation of the UII.
When DoD requires this marking it shall 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.
To create a compliant unique item identifier, all required information about the part and the organization producing it is linked together – concatenated – into a single data field of up to 50 numeric, alphabetic or alphanumeric characters. This data must be entered into the IUID Registry to “ensure uniqueness” of each item submitted for listing in the registry. This unique item identifier can also see use within manufacturing, maintenance and logistics organizations for any number of varied purposes.
Marking of tangible items or assets in accordance with IUID policy is mandated by incorporating Defense Federal Acquisition Regulation Supplement (DFARS) clause 252-211-7003 in DoD contracts.

Famous quotes containing the word description:
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (17431826)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“It is possibleindeed possible even according to the old conception of logicto give in advance a description of all true logical propositions. Hence there can never be surprises in logic.”
