IUID Equivalents

IUID Equivalents are unique identifiers that meet established criteria to allow for their usage as UIIs. This link provides an overview of the criteria and indicates that accepted IUID Equivalents identified thus far.

The Final DFARS Rule on 'Unique Item Identification and Valuation' was published in the Federal Register on April 22, 2005. Paragraph 211.274-2(a) states that unique item identification, or a DoD recognized unique identification equivalent, is required for situations enumerated in subparagraphs (1), (2), (3), and (4) of 211.274-2(a). A commercial identifier can be considered by the DoD for use as a DoD IUID Equivalent if it meets all of these criteria.

  1. Must contain an enterprise identifier
  2. Must uniquely identify an individual item within an enterprise identifier, product or part number, and
  3. Must have an existing Data Identifier (DI) or Application Identifier (AI) listed in American National Standard (ANS) MH10.8.2, Data Identifier and Application Identifier Standard.

The commercial unique identifiers meeting these criteria that the Department recognizes as DoD IUID equivalents are the:

  • EAN.UCC Global Individual Asset Identifier (GIAI) for serially-managed assets,
  • EAN.UCC Global Returnable Asset Identifier (GRAI) for returnable assets, and
  • ISO Vehicle Identification Number (VIN) for vehicles.
  • Electronic Serial Number (ESN) for cellular telephones only
  • Mobile Equipment Identifier (MEID) for cellular telephones only
  • Cellular Mobile Telephone Identifier (CMTI) for cellular telephones only

In addition to these equivalents, the data requirements of 14 CFR Part 45, Identification and Registration Marking, for only aircraft, aircraft engines, propellers, and propeller blades and hubs are consistent with the data elements required by our IUID constructs.
