A National Stock Number is the official label applied to each item repeatedly used, bought, stocked, or distributed by the
Department of Defense (DoD). When a NSN is assigned to an item, data is assembled to describe that item. Some data elements
include information such as an item name, manufacturer's part number, unit price, and physical and performance characteristics.
NSNs are an essential part of the DoD Supply Chain used in acquisition, managing, moving, storing, and disposal of material.
Whenever a new weapon system is developed, the DoD Component responsible for the new weapon system will identify the spares
needed to maintain the weapon system throughout the life cycle. Spares that do not have NSNs assigned are identified and requests
for NSN assignment are sent to the Logistics Information Services by the DoD Component. In turn, the Logistics Information Services
processes the requests by assigning new NSNs.
Other materials, not tied specifically to a weapon system, may require the need for NSN assignment as well. Each DoD Component has
a unique process for identifying a requirement for new NSNs. It starts with a Warfighter need for an item which generates an order.
The order is typically submitted using a manufacturer's reference number on a DD Form 1348-6, through the DoD Component supply
system. It is at the discretion of the DoD Component to determine the need for NSN assignment.
Each DOD Component has designated personnel with decision making authority for NSN assignment requests:
Army, Navy, and Marine Corps - have designated provisioner's with this responsibility
Air Force designated personnel are referred to as Cataloging Managers (CATMs) or Cataloging Focal Points at each Air Logistics Center
