National/NATO Stock Number (NSN) 

Assignment

NSNis the of�icial label applied and must be assigned to any item subject to repetitive procurement, 

storage, distribution within the DOD and Federal Government. Centrally managed items will be named, 

described, identi�ied, classi�ied, and numbered (cataloged) in the Federal Catalog System (FCS) or NATO 

Codi�ication System (NCS). 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 identi�ied 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 speci�ically 

to a weapon system, may require the need for NSN assignment as well. 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 CAGE and part number (reference number), unit price, and physical and / or performance 

characteristics. NSNs are an essential part of the DOD Supply Chain used in acquisition, managing, 

moving, storing, and disposal of material. 41 CFR Subpart 101-30.3 and DoDM 4100.39 (FLIS) –

Cataloging Items of Supply, and DoDM 4140.01 – DoD Supply Chain Materiel Management Procedures, 

and NATO Manual on Codi�ication (ACodP-1).

Each DOD Component has designated personnel with decision making authority for NSN assignment

requests:

Army, Navy, and Marine Corps have designated provisioners and / or Material Master Cells with this responsibility.

Air Force has provisioners and designated personnel referred to as Cataloging Managers (CATMs) or Cataloging

Focal Points at each Air Logistics Center.
