UID labels are important part of the UID marking procedure of the DoD. The data that are required to be etched on the UID labels are provided by the DoD so that contractors can mark the labels as per the requirements of the organization. Moreover, it is mandated that the marking methodologies should be so that the marking should be readable throughout the functional life time of the item. Again, the labels should be affixed to the part or item permanently so that it would help the item tracking process of the DoD.
Verification of UID labels
Primarily, it is the responsibility of the contractors to assure that the UID labels are manufactured according to the UID standards. If the contractors purchase the labels, nameplates or the decals from the vendors, the DCMA is required to assure that the machine readable markings of the items are developed in accordance with the requirements of MIL-STD-130. If the contractors procures the UID labels form the vendors, he should provide a certificate of conformance from the vendors that mentions that the UID labels are manufactured according to the MIL-STD-130 standard. The DoD has recommended that the grade of marks is stated by the COC at the time of construction of the labels. The SAE or the ISO standards is used to determine the grade of the marking. Although the vendors present a Certificate of Conformance assuring that the labels are marked as per the UID standards, the contractors need to investigate the markings and their compliance as per the specific requirements.

Specification of Materials
There is no specification about the materials of the UID labels in the MIL-STD-130. It only requires that the materials should ensure durability. The contractors are allowed to use any metallic as well as non-metallic materials for the construction of the labels. However, the contractors need to make sure that the material of the labels doesn’t affect the item or its performance. When it comes to durability, the UID labels should be able to withstand environmental changes, heat and other cleaning process and chemicals.
Compliance for the UID Marking
The DoD instructions for UID marking informs that the UID data should be engraved on the UID labels in the form of 2D data matrix code. The standard has mentioned about the font type, and size of the symbols that are etched on the plates. The contractors should try to print as large mark as possible to ensure that the codes are readable. Although the barcodes are machine readable symbols, the MIL-STD-130 requires that there should be human readable information on the labels along with the machine readable codes.
The UID labels are verified while submitting the data to the UID Registry. Some of the products are checked during construction, while others are checked during the delivery. But the UID Registry has the right to reject the application if it finds the marking or the manufacturing of the labels not meeting the standard. Moreover, the contractors need to make sure that all the labels are manufactured according to the UID standard so that they get accepted in the UID Registry.
