Item Designator Number

Item Designator Number (IDN) is used to control the item subsystem and referred to for reportable items only.

The IDN is used for the control and identification of equipment and its repair parts. Marine Corps personnel use the IDN to identify principle end items, major components, secondary item repairable, and modification kits. The Marine Corps Logistics Command (MARCORLOGCOM) is responsible for the IDN.
