    Is the serial number the equivalent to the unique-item identifier?


    Answer

    Please review the information below at http://dodprocurementtoolbox.com/site-pages/unique-id-overview.
     
    " The DoD recognizes six commercially used unique identifiers as IUID equivalents: the vehicle identification number, or VIN; the cellular mobile telephone identifier, or (CMTI); the mobile equipment identifier, or MEID; the electronic serial number, or ESN; the Global Individual Asset Identifier, or GIAI; and the Global Returnable Asset Identifier, or GRAI. These IUID equivalents may be used in lieu of assigning a new UII."
     
    An item serial number is a part of the construct of a unique-item identifier.
     
    " A Construct 1 UII is made by connecting three pieces of data: an issuing agency code designating what kind of enterprise is ensuring the uniqueness of the UII, an identifier for that enterprise, and finally a serial number the enterprise has uniquely assigned to that item. A Construct 2 UII is made by connecting four pieces of data: an issuing agency code designating what kind of enterprise is ensuring the uniqueness of the UII, an identifier for that enterprise, the original part number of the item, and finally the serial number uniquely assigned to that item within the part number."
