UII Overview

UII Overview

The Department of Defense (DoD) now requires Unique Item Identifiers (UIIs) for all
products sold to the DoD by private vendors. A UII can be thought of as a Social Security
number for each part. The UII must be encoded in a Data Matrix ECC 200 symbol that
conforms to the data structure defined in the DoD's "Guide for Uniquely Identifying Items."
UII Elements
UIIs 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:
(1.) Enterprise
Identifier (EID):
A number
assigned and
controlled by a
specific agency
(e.g. Dunn and
Bradstreet or
GS1 US).
Encoding a UII
The information in a Data Matrix UII also includes a compliance indicator, data qualifiers,
and data element separators. None of these elements are part of the final UII . When
UII-Only Mode is enabled in the imager, the characters that are not part of the UII are
removed from the decoded symbol data. Only characters that make up the UII are passed
on to the host computer. Otherwise, the symbol is rejected.
