UID Labels and Nameplates

About UID and IUID Marking

Unique Identification (UID) and Item Unique Identification (IUID) are part of the identification marking process mandated by the United States Department of Defense (DoD). UID and IUID are permanent marking methods used to give military property and Government-Furnished Property (GFP) a Unique Item Identification (UII).

UID and IUID marking is a systematic process to globally and unambiguous distinguish property and ensure data integrity throughout an item’s lifecycle through the use of two-dimensional (2D) Data Matrix ECC 200 Symbols.

UID and IUID marking is required for all military property and equipment with an acquisition cost over $5,000, equipment that is mission essential, controlled inventory, or serially-controlled.

DoD Standards and Specifications

Labeling is required for DoD vendors. Express UID and IUID nameplates satisfy the following DoD standards and specifications:

• MIL-STD-130 – this standard specifies the marking requirements and methods for identification of military property produced, stocked, stored, or issued by or for the DoD. This standard further provides information for the implementation of machine-readable information (MRI) processes for item identification marking and facilitating automatic data capture.
• MIL-STD-13231 – this standard specifies the DoD’s uniform marking requirements for electronic items.
• MIL-STD-129 – this standard specifies the DoD’s marking requirements for shipment and storage.
• GG-P-455 – this specification covers the requirements for photosensitive anodized aluminum sheets and foils. For purposes of this specification, foils referred to in this specification are defined as material 0.010″ and thinner.
• MIL-DTL-15024 – this performance specification covers the physical characteristics of plates, tags, and bands (identification devices) used for identification of equipment. Examples of information to be marked on the identification devices are covered in the applicable specification sheets.
• MIL-P-19834 – this detail specification covers adhesive-backed metal foil identification or instruction plates for use as internal and external equipment identification or instruction.
• MIL-A-8625 – this specification covers the requirements for 6 types and 2 classes of electrolytically formed anodic coatings on aluminum and aluminum alloys for non-architectural applications. This includes chromic acid anodizing, non-chromic acid anodizing, sulfuric acid anodizing, and hard anodic coatings.
• A-A-50271 – this commercial item description covers identification plates for attachment to equipment to provide identification and other miscellaneous data.
• SSP50007 – this document establishes the Inventory Management System (IMS) barcode label specifications and requirements for the International Space Station (ISS) Program.
