It’s a question we get a lot when being asking for 2D Data Matrix Codes to be marked or engraved into a product. So where did UID come from? The United States Department of Defense (US DoD) requires as of September 2007 all acquisitions over $5,000 for mission critical, controlled inventory, serial number controlled and consumable items to have UID codes. The UID mark is a specific type of 2D Data Matrix Code, the difference being a 2D UID is a unique string of data points that the US DoD has deemed critical to attain its goals for asset visibility and product life-cycle management and accountability.
The preferred method of applying 2D UIDs is a type of Machine Readable Medium called a 2D Data Matrix ECC 200 Symbol, and requires a verification process to ensure the UID meets the MIL STD 130 requirements. Additionally, once a UID code has been created and place on a product provided to the US DoD, that unique string must be entered into the IUID Registry. This registry is the single source of data tracking all assets meeting the minimum criteria that are sold to the US DoD.
The preferred tool to apply a 2D UID is with the use of a laser. Lasers provide a permanent mark that can withstand the test of time and wear which is essential for military applications. Accubeam Laser provides services to apply the 2D UID directly to a part or on product tags that can be affixed to your products during the production cycle. Contact Accubeam via phone or the Request a Quote option at the top of the page to learn more about the process.
