4. Explanation of Columns (Section IV).
a. National Stock Number (NSN) Index.
(1) Stock number column. This column lists the NSN by National Item Identification Number (NIIN)
NSN
sequence. The NIIN consists of the last nine digits of the NSN (i.e., 5305-01-674-1467). When using this column
NIIN
to locate an item, ignore the first 4 digits of the NSN. However, the complete NSN should be used when
ordering items by stock number.
(2) Fig. column. This column lists the number of the figure where the item is identified/located. The
figures are in numerical order in section II and section III.
(3) Item column. The item number identifies the item associated with the figure listed in the
adjacent FIG. column. This item is also identified by the NSN listed on the same line.
b. Part number Index. Part numbers in this index are listed by part number in ascending alpha-
numeric sequence (i.e., vertical arrangement of letter and number combination which places the first letter
or digit of each group in order A through Z, followed by the numbers 0 through 9 and each following letter
or digit in like order).
(1) CAGEC column. The Commercial and Government Entity Code (CAGEC) is a 5-digit numeric
code used to identify the manufacturer, distributor, or Government agency, etc., that supplies the item.
(2) Part number column. Indicates the primary number used by the manufacturer (individual,
company, firm, corporation, or Government activity), which controls the design and characteristics of the
item by means of its engineering drawings, specifications standards, and inspection requirements to
identify an item or range of items.
(3) Stock number column. This column lists the NSN for the associated part number and
manufacturer identified in the PART NUMBER and CAGEC columns to the left.
