Overview of IUID and UII
Overview of IUID and UII
The Department of Defense (DoD) now requires “Item Unique Identification” (IUID) for all
products sold to the DoD by private vendors. A Unique Item Identifier (UII) is like 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:
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 is
enabled in the Quadrus EZ, 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 com-
puter. Otherwise, the symbol is rejected.
