|Basics of UID|
|We at William Frick & Company are experts at navigating the complex terrain of unique identifier (UID) codes for military contracts. Veteran-owned Frick has more than 35 years of experience in the field of asset identification, so our experts understand what you need to do to meet UID, MIL STD 130 and MIL-STD-139 requirements.|
|UID: Unique Identification Code|
|Regulations for the Department of Defense (DoD) spell out which items delivered to them under contract have to be labeled with a Unique Identification (UID) code. DoD uses this information to manage logistics, replace and repair assets, and for financial accountability.
Most of the items that DoD obtains must adhere to a specific five-step process from cradle to grave:
1. Contract Requirement: DoD contracts indicate which equipment, property, plants, operating materials and supplies need to be marked with a UID code.
2. Create/Generate: Industry suppliers and manufacturers throughout the supply chain assign and apply UID codes to ensure the uniqueness of their products. These UID markings must be machine readable.
3. Capture: DoD establishes the “birth” record of the asset by capturing the component data elements to create the UID in the Automatic Identification Technology (AIT) /Automated Information System (AIS).
4. Use: Functional stakeholders use UID as a primary or alternate key in the AIS to access or update item information based on its UID.
5. Disposal: DoD / GSA records the “termination” of the UID at the time of the item’s disposal.
Rules Governing UID
|What Must be Marked?|
|According to DFARS Clause 252.211-7003 Item Identification and Valuation (JUN 2005), the following items require UID markings:
|Regardless of value, the following items need a UID mark:
|What are the Benefits of UID?|
|The use of machine-readable marks provides significant benefits to DoD. These marks improve data quality. They make data capture faster and more precise. They ensure integration and interoperability across organizational boundaries. They facilitate item tracking in DoD’s business systems. Plus they provide reliable and accurate data for program management, engineering and accounting purposes.|
|What Does the Mark Look Like?|
|Items must be marked with machine-readable information (MRI). The minimum requirement for DoD is the Data Matrix ECC200 symbol per ISO 16022. The data matrix code needs to use syntax of ISO/IEC 15434 and semantics of ISO/IEC 15418 or ATA Common Support Data Dictionary (CSDD). The ensuing code can then be translated into a 2D machine-readable matrix code, which is applied to the hardware via label, etching or other means.|
|There are several advantages to using a 2D data matrix symbol:
|Formatting UID Data|
|How Should Items Be Marked?|
|The UID is constructed from its discrete component data elements:|
|UID Construct 1||UID Construct 2|
|If the serial number is unique within the enterprise identifier||If the serial number is not unique within the enterprise identifier but is unique within the part number|
|UID = EID+SN||UID = EID+PN+SN|
|The Enterprise Identifier (EID) portion of the UID is determined by the person who assigns the serial number to the item:|
Original Part Number
|(EID) = 15090
(PN) = 1234567-1
(SN) = 10001
|The standard data capture mechanism for transmitting UID data from contractors to DoD is Wide Area Work Flow (WAWF). It is an electronic application designed to reduce paperwork at DoD.|
RFID Tags Key to Our Asset Management, February 21 2011
We have found that our RFID asset management system is especially useful for tracking portable tools within our facility, as well as for keeping them from mysteriously walking out the front gate. We also use RFID labels in our inventory and shipping systems, and have found them more versatile than our old barcode system.
New to Military Contracts and UID Codes, February 21 2011
Our experiences dealing with military contracts have actually made all of our operations more efficient. We pay a lot more attention now to using custom labels and nameplates on our products. We have started using RFID tags as asset tagging labels so that all of our manufacturing, inventory management, and shipping operations can be integrated into a single computer-monitored tracking and accounting system.
