The DoD UID Program began in 2004 to track all items purchased by the Department of Defense (DoD.) Each UID number must remain unique unto itself for accurate tracking. Minimally, every UID label must contain a CAGE Code (Commercial and Government Entity) or DUNS Number (Data Universal Numbering System) and a Serial Number. Including other information is optional. We’ll show you how to choose the right information for your labels…
Choosing a Construct:
If your label does not contain a part number at all, or if the part number is not encoded into the Data Matrix with the Cage Code/Duns Number and Serial Number, it is Construct 1. If your label contains a Part Number in addition to the Cage Code/Duns Number and Serial Number, it is Construct 2.
Choosing a Format:
There are two formats to choose from: Format 6 and Format 12. The Formats are differentiated by the two different types of text used to identify the Cage Code, Serial Number, and Part Number (if applicable.)
Tip: If you are providing UID labels for the Air Transport Association, you will use Format 12.
Choosing a Layout:
As some items for the Department of Defense (DoD) may have tight space constraints, there are several options for the layout of the label.
DoD’s preferred layout is 2.400″ x 1.250″, contains three linear barcodes, one data matrix barcode, and “human readable” text.
If a smaller label is needed, the linear barcodes can be removed leaving just the data matrix code and human-readable text for the Alternate Layout #1. This label would measure out to exactly 2.000″ x 0.750″.
If there are extreme space limitations, the “human-readable” information may also be eliminated to leave a properly encoded data matrix. This is the Alternate Layout #2 and would measure out to exactly 0.625″ x 0.625″.
Note: If your item is still too small to label, the Mil-Std-130 specification does allow for a “Bag & Tag” solution to label the packaging for the item.
An Expanded Layout is also available if needed. For this layout, any additional information added to the label will not be encoded in the data matrix, but will be separated by its own identification. Some of the additional data that can be included on the UID label includes an NSN Number, Contract Number, and even a Company Logo.
If you have any specific questions regarding your layout or what information should be included on your labels, we recommend contacting your Contract Administrator directly.
Choosing a Material:
As with all other labels, it is extremely important to pick the best material for the environment the label will be in. UID labels should last the lifetime of the item they are identifying.
The most popular materials for UID labels are:
