DOD UID MARKING

2D Code

Unique Identification Marking, or UID marking, is a part of the UID Compliance process mandated by the United States Department of Defense. It is a permanent marking method used to give equipment a unique ID. Marking is essential for all equipments with an acquisition cost of over $5,000, equipment which is mission essential, controlled inventory, serially-controlled, orconsu consumable. UID-marking is a set of data for assets that is globally unique and unambiguous. The technology used to mark an item is 2D Data Matrix ECC 200 Symbol. UID marking ensures data integrity and data quality throughout life; it also supports multi-faceted business applications. DoD is enabled by UID marking standard to reach established goals and objectives by enhanced total asset visibility, improved lifecycle item management and accountability and clean financial audits.

As per the memorandum issued by the Department of Defense (DoD), UID-marking is a must for all solicitations issued on or after Jan. 1, 2005. Also the US Department of Defence has made it mandatory for all federal contractors to have UID-marking on their government furnished military and non-military equipments by September 30, 2007. Only after the products have UID-marking containing uniquely identified numbers, they are eligible for IUID Registry.

Application

Per the UID standard, a 2D Data Matrix bar code that is applied with either direct part UID-marking techniques or labels must also prove to be generated to a level of quality that meets the standards set by the Internatioonal Organization for Standardardization (ISO) and the Society of Automotive Engineers (SAE). UID Markings and 2D Matrix Barcode Symbols can be created on a variety of surfaces. Generally UCC.EAN, ANSI MH 10.8.2 or ATA style descriptors are used for UID-marking symbol. Vendors supplying parts to the Department of Defense are required to supply parts with UID Data Matrix Symbols conforming to MIL-STD 130M standard. By using a Data Matrix Symbol laser etching system to engrave a UID onto each part, items can be uniquely identified by manufacturer, part number and serial number.

Marking Methodology

UID bar code must be maintained as a readable bar code throughout the entire life of the item; hence strong consideration must be given to the UID-marking methodology. Metal tag with a permanent adhesive or durable polyesterlabel are suitable for many environments but other marking items such as laser etch, dot peen, chemical etch or ink jet can also be used for direct part Unique Identification.
