What is Unique Identification (UID)?

The following is condensed from the UID support webpage, www.uidsupport.com, which is maintained by the RVSI Symbology Research Center.

Laser bonding and marking are MIL spec methods for meeting the requirements of UID.

UID is a new globally unique "part identifier" containing data elements used to track DoD parts through their life cycle.

UID Data is encoded into Data Matrix symbols that are applied to parts using Direct Part Marking processes (DPM). The DoD has moved to this transformation technology to facilitate electronic data capture and transmission.


UID is a mandatory DoD requirement for all solicitations issued on or after Jan. 1, 2004. The DoD Download --- The DoD Guide to UID - Version 1.5 requires the application of Data Matrix symbols to parts in the following categories:

• Costs over $5,000.
• Serially managed.
• Mission essential.
• Controlled inventory.
• A consumable item or material where permanent identification is necessary.
