How Can I Generate a UID Code?

UID Codes are used as a permanent marking method in order to give equipment a unique ID. UID Codes utilize the Data Matrix ECC200 bar code symbology - this standard is supported by TEC-IT.

Beside selecting Data Matrix as bar code type the encoded data structure has to comply with the rules outlined in the „MIL Std 130“ specification (see also this FAQ).

Creating the world wide unique UID number can be achieved by the following methodologies (constructs) and approved equivalents:

• UID Construct 1, composed of Issuing Agency Code, an Enterprise Identifier, and a Serial Number unique within the Enterprise
• UID Construct 2, composed of Issuing Agency Code, an Enterprise Identifier, a Part Number and a Serial Number (unique within the Part Number)
• The following IUID Equivalents are also approved: Vehicle Identification Number (VIN), Global Returnable Asset Identifier (GRAI), Global Individual Asset Identifier (GIAI), Electronic Serial Number (ESN, typically assigned to cell phones)

Accepted Issuing Agencies:

• DoD and NATO
• D-U-N-S (Dun & Bradstreet)
• GS1 (formerly EAN/UCC)

After getting a world wide unique enterprise ID from one of the listed Issuing Agencies, suppliers can number their products with UID Construct 2. Often an existing serial number management can be re-used for that process. Suppliers in the US can use the CAGE code as enterprise ID. In other countries the NATO or GS1 can issue enterprise IDs. If a company already owns a DUNS number it can be used as well.
