STANDARD SUBJECT
IDENTIFICATION CODES
Basic guidelines for categorizing cor-
respondence in the Navy and Marine Corps is set
forth in SECNAVINST 5210.11 (Standard Sub-
ject Identification Codes). This instruction is
divided into three sections and is designed to meet
the needs of the entire Department of the Navy
in order to have a standardized system for
classifying, arranging/filing, and referencing
various types of Navy and Marine Corps
documents by subject. The three sections contain
the following information:
Section I (List of Standard Subject Identi-
fication Codes). A convenient numerical
classification outline consisting of 14 major
numerical series which are subdivided into
primary, secondary, and tertiary subjects is pro-
vided in this section. Figure 3-5 shows an
example of a page extracted from this section.
Section II (Name-Title Subject Identifica-
tion Codes). This section provides alphabetic or
alphanumeric codes for names and titles which
are used frequently in the Navy Department.

Section III (Alphabetical Guide to
Standard Subject Identification Codes). This
section provides an alphabetical list of all primary,
secondary, and tertiary codes which are listed in
Section I. Figure 3-7 shows an example of a page
