NATO Codi�ication System

The Foundation of all Logistics Systems and the Cornerstone of 

NATO Logistics

The North Atlantic Treaty Organization (NATO) Codi�ication System (NCS) is 

governed by the NATO Codi�ication Allied Committee 135 (AC/135) and is composed of 

representatives from each NATO and partner nation along with the NATO Support and 

Procurement Agency (NSPA), which is NATO's principal logistics support management 

agency.

The AC/135 provides and promotes the NCS as the primary means of codi�ication used by 

Armed Forces, Government, and Industry in support of interoperable and effective global 

logistics operations. Through codi�ication, AC/135 manages all aspects of classi�ication, 

item identi�ication, and NATO Stock Numbers for materiel used by NATO and Sponsored

deployed in an operational scenario can be assured of getting the right items to 

successfully complete their mission.
