The Management Control Number (MCN) is a 13-character number similar to the national stock number except for the alpha code in the seventh position, which represents the major Army command or activity that made the assignment. Characters 8 through 13 will be assigned in ascending serial sequence independent of the federal supply classification (FSC). Activities assigning MCNs should ensure that the proper FSC is used for each item.
