What is UID Marking?

UID (Unique Identification) marking has become a critical requirement in the U.S. Department of Defense (DoD) supply chain. It allows for the permanent, machine-readable identification of items, enabling full traceability throughout the lifecycle of each asset — from production to deployment to disposal.

Each item is marked with a unique Data Matrix code that ties directly to key item information stored in the IUID Registry, allowing for real-time tracking and accurate asset management across defense operations.

The Role of MIL-STD-130 and DLA Compliance

All UID marking must comply with the DoD’s MIL-STD-130 standard, which outlines the rules for durable marking, data formatting, and verification procedures. According to this standard:

• A compliant UID must include a 2D Data Matrix barcode
• Marking must be permanent (e.g., laser etching, chemical etching, UV printing)
• Data structure must follow ISO/IEC 15434 and 15418 standards
• All markings must pass quality verification tests and be readable under MIL-STD-130 guidelines

For vendors supplying the Defense Logistics Agency (DLA) or any other DoD agency, UID compliance is no longer optional — it is a mandatory prerequisite for many NSNs (National Stock Numbers).

Why UID Marking Matters More Than Ever

As global defense systems become more complex and interconnected, traceability is now a matter of both logistical efficiency and national security. UID marking enables:

• Automated inventory and maintenance tracking
• Reduction in counterfeit parts and unauthorized substitutions
• Streamlined audits and inspections
• Long-term cost savings in lifecycle management

UID marking also plays a key role in predictive maintenance, asset redeployment, and contract compliance.
