a nine-digit national item identification number (NIIN),
The NIIN consists of a two-digit national edification
bureau (NCB) code (which will be discussed
separately) and seven digits which in conjunction with
the NCB code, uniquely identify each NSN item in the
Federal supply distribution system. Figure 4-2 shows
the elements of an NSN in the order they are written.
Cognizance Symbol
A two-part cognizance symbol is used by the Navy
to provide supply management information. Then are
94 cognizance symbols currently in use. The majority
of stock transactions aboard ship use cognizance
symbols 1H, 9C, 9G, 9N, 9Q, and 9Z. The first part is
a single number that tells in what the stores account the
material is carried in the supply system. Briefly, the
numerical part of the cognizance symbol indicates the
following:
1,3,5,7
9
2,4,6,8
Material is held in the Navy Stock
Account (NSA). When this material
is issued, it must be paid for by the
requisitioner.
Material purchased by the Defense
Stock Fund and held in NSA. When
this material is issued, it must be paid
for by the requisitioner.
Material held in the Appropriations
Purchases Account or nonstores
account. This material is issued
without charge to the requisitioner.
The second part of the cognizance symbol is a
single-letter code that designates the inventory manager
or inventory control point (ICP) that has cognizance, or
control, of the material. These inventory managers may
be Navy or Defense activities.
Material Control Code
The material control code (MCC) is a single letter
code assigned by the inventory manager to indicate the
rate of usage or to designate those items having special
reporting and/or control requirements. The MCC is
discussed further in the latter part of this chapter.
National Codification Bureau (NCB) Code
An NCB code is a two-digit code which is included
as the fifth and sixth digits of an NSN or a NATO stock

number. It identifies the country that assigned the stock
number or it indicates that the stock number is used by
two or more countries. The NCB codes currently
assigned are listed in the NAVSUP P485.
National Item Identification Number
The national item identification number (NIIN) is
a nine-digit number which identifies each item of
supply used by the DOD. The NIIN indexes or relates
to identification data information which makes it
different from every other item. The amount and type
of identification data depends on the item and its
intended use. Although the NIIN is part of the NSN, it
is used to independently identify an item. Except for
identification lists, most Federal supply catalogs are
arranged in NIIN order.
Stock records are also maintained in NIIN order as
are load lists and consolidated allowance lists.
Navy Item Control Numbers
Items of material that are not included in the Federal
Catalog System, but stocked or monitored by the Navy
Supply System, are identified by Navy item control
numbers (NICNs). NICNs are 13-character item
identification numbers. They are assigned by ICPs or
other Navy item managers for permanent or temporary
control of selected non-NSN items under their
