In this chapter, we will discuss the physical
security provided to all mail and the Navy Information
and Personnel Security Program as it applies to
classified material sent in the mail. We will also
discuss the requirements for maintaining the security
of mail and equipment, random inspections, probable
cause searches, and instructions on what to do if a
suspected letter or parcel bomb is found.
The word security has two meanings. The first
meaning applies to the internal and external security
provided to all mail. This means that when you or
anyone else entrusts an article to the postal system, you
can depend on it arriving at its destination safely and
The Military Postal Service (MPS) and the U.S.
Postal Service (USPS) rank second to none in the
security given to mail articles that are accepted for
delivery. The privacy to which every letter and parcel
is entitled is established by law, and certain articles
specifically, registered and insured mailare given
special protection against loss or damage.
The second meaning of the word security applies
to transmitting classified material through the postal
system. The relative safety from compromise is amply
illustrated by the fact that certain classified matter is
transmitted regularly through registered mail
Q1. Which agencies are rated as second to none in
providing security for military mail?
GENERAL SECURITY PROCEDURES
S e c u r i t y o f t h e m a i l i s a c o m m a n d
responsibility. Mail consigned for transmission is
always delivered into the hands of a responsible
postal agency, military or commercial carrier, or the
authorized agents of these carriers who can make a
reasonable guarantee of onward transmission to
achieve ultimate delivery as intended. You should
never turn mail over to a haphazard or makeshift
means of transmission.
In general, registered military mail may be
transported outside the Continental United States
(CONUS) and Canada, only in U.S. flag certified
cargo air carriers, and while in U.S. custody or
control. Military mail dispatching agents are
responsible for the security regulations covering the
mail route for which they are responsible as well as
the next onward transfer point. Where it appears that
security regulations will not be met, the dispatching
agent will withdraw the registered mail from
transmission and request instructions from the
Official mail containing classified material
transmitted outside CONUS should arrive safely at its
destination if the following conditions are met:
Addressed properly with complete and correct
mailing address as contained in the Standard
Navy Distribution List ( S N D L ) , O P N AV
Acceptance as registered mail into the U.S.
domestic postal system in CONUS
Acceptance as registered mail into the military
postal system overseas

P e r s o n n e l S e c u r i t y P r o g r a m R e g u l a t i o n ,
OPNAVINST 5510.1, provides all Navy activities and
personnel with detailed regulations and guidance for
classifying, marking, handling, and methods of
transmission of classified material.
Q2. What type of air carrier is used to transport
registered mail outside CONUS and Canada?
MAIL CENTER KEYS

kept to a minimum.
The OMM will maintain
accountability of all keys held by others.
As the Official Mail Manager (OMM), you are
responsible for your key and for informing your
assistants of their responsibilities for the keys assigned
