TheItem Unique Identification (IUID) system plays a critical role in theidentification and classification of items that are to be submitted to theDepartment of Defense (DoD). Treated asa universal method of parts identification by the DoD, theIUID helps in locating, controlling and valuing all the defense relatedqualifying assets. IUID requirements criteria are now integrated in the DoDfinancial improvement and audit readiness plans.
Asper the UID Compliance norms, the IUID of items is mandated to be marked with anon erasable 2-dimensional data matrix for each qualifying item. A globallyunique and unambiguous Unique Item Identifier (UII) is constructed to beencoded in the IUID data matrix. As the IUID marking is machine-readable, thereis minimal chance of human error. The acquisition records and inventory is alsoimproved.Apart from easy identificationof items as per the UID Compliance setting, the IUID marking also helpsaccelerate the receipt and acceptance process, thereby making it easy for theDoD to submit payment to its vendors at appropriate time without making anyfurther delay. The UID compliance has mandated all defense items to beregistered with the IUID registry.
Criteria forsubmitting in the IUID Registry:
Before registering with the IUID Registry, All the government manufacturing activities as well as commercial manufacturers are mandated to be registered with the Central Contractor Registration (CRR) system.
All users are required to register themselves to have login credential access rights of the IUID Registry. But for that, you need to be an U.S. Government employee or a Contractor with approval from the DoD Program Manager to obtain the login access to the IUID Registry.
For those who plan to conduct business with Government Furnished Property, submitting detailed info to the IUID system is a must.
Asper the UID compliance, of the several standards used in IUID marking, the MILSTD 130 is the most fundamental item identification marking standard. Of late,certain changes were made to the original MIL STD 130. On December 17th2007, a new version of the standard (MIL-STD-130N) was officially released. Asper the new MIL-STD-130N, specific criteria have been issued for markingrequirements and identification methods of military items produced, stored,stocked, and issued by the Department of Defense.
Rules of the newMIL-STD-130N standard:
Henceforth, the UID will be restricted to 50 characters only.
For item identification marking, the MIL-STD-130N standard has criteria for both free text and machine-readable information (MRI) marking.
Now labels which include name plates, data plates, and ID plates can be made up of metallic or non-metallic materials.
The standard clearly states that a label may be of any similar or can also be of different material than that of the item to which it is affixed. This basically means that label of one material can be affixed to the identified item of another material.
The verification is defined in the new MIL-STD-130N standard as ?Confirmation by examination, and provisions of objective evidence, that the item identification marking requirements specified in this standard and the associated contract have been fulfilled.?
A contractual warranty between the Government and the contractor expressing the nature, usefulness, or condition of the items in terms of hours, days, months, number of operations has to be according to the MIL-STD-130N standard.

The DoD UID labels are one of the ways of marking the DoD items with unique identification so as to enhance their traceability. The Department of Defense has mandated that the labels should be MIL-STD-130 N compliant so that all markings of the items should maintain a standard. As the marking and serialization process of the items are the essential aspect of item management and tracking, the UID marking that doesn't comply with the standards are rejected by the department. The DoD UID labels are marked with 2D Data matrix codes that are machine readable either by direct part marking or by applying permanent UID labels.
Apart from the feature that the unit acquisition cost of the items should be more than $5000, the other criteria that enables the items to have unique identification are
?The items are controlled inventory
?Serially managed
?Mission essential
?The item is customable where permanent identification is necessary.
As the basic identification marking standard of the DoD UID labels are regulated by the MIL-STD-130 N, it is mandatory for the contractors to obey the instructions provided in the standard. The standard has issued some specifications for the marking requirements and the marking methods of the UID.
Depending on the requirement of the UID marking of the item, the labels (nameplates, ID plates or Data plates) can be constructed with either metallic or non-metallic materials.
The DoD UID labels of the items are made of material either same or different that that of the material of the item. It is essential that the material of the labels shouldn't cause any damage to the items and should get affixed to the material of the items or parts.
The standard has limited the number of characters of the UID marking of the labels to 50.
The criteria for machine-readable and human readable information of the UID data on the DoD UID label are declared by the MIL-STD-130 N.
The validation and verification of data are mandatory for each submitted data.
The warranty of contract between the government and the contractors states about the nature, utility and condition of the objects.
The drawbacks of the MIL-STD-130 have been rectifying for the convenience of the contractors and better management of the UID items. The latest version of the MIL-STD-130 N, which was released on December 17 2007, has mentioned the criteria for DoD UID labels, validation and verification. According to the standard, different lighting methods should be used for the different part marking. The contractors are required to follow the instructions provided for marking of UID and manufacturing UID labels.
The DoD UID labels are verified according to the cell modulation, cell size, cell contrast, print growth, reference decode, fixed pattern damage, unused error correction, axial non-uniformity, minimum reflectance, and grid non-uniformity. When the outsourcing of UID is considered, the DoD should ensure that the service should follow all the steps mandated by the standard. Even, the DoD UID label generating software must comply with the standards of MIL-STD-130 N.
