UID Overview

UID Overview

The Department of Defense (DoD) now requires Unique Identification (UID) numbers

for all products sold to the DoD by private vendors. A UID number can be thought of as

a Social Security number for each part. The UID number must be encoded in an ECC

200 Data Matrix symbol that conforms to the data structure defined in the DoD’s “Guide

for Uniquely Identifying Items.”

UID Elements

UID numbers come in two forms, called Construct 1 and Construct 2. The following is

an example of Construct 2. Construct 1 is identical, except that it doesn’t include a part

number. Construct 2 is composed of three basic elements:

UN ABCD 98/76 123-AC

Encoding a UID

The information in a Data Matrix UID also includes a compliance indicator, data qualifiers,

and data element separators. None of these elements are part of the final UID number.

When UID-Only Mode is enabled in the MS-Q, the characters that are not part of the UID

number are removed from the decoded symbol data. Only characters that make up the UID

number are passed on to the host computer. Otherwise, the symbol is rejected.
