NATO Codification - the Global Language of Logistics

The NATO Codification System (NCS)


The NATO Codification System is the official programme under which equipment components and parts of the military supply systems are uniformly named, described, classified, and assigned a NATO Stock Number. More and more nations outside NATO recognise the benefits of adopting the NCS for internal purposes, for dealing with NATO nations and for dealing with each other...More


The NATO Codification System is managed and run by a NATO Cadre Group consisting of the National Directors on Codification Allied Committee 135 (AC/135). Mission of AC/135 is to provide participant Nations with a uniform NCS as the global reference standard for materiel identification, and as a key enabler to support NATO and multinational interoperability, and harmonised logistic systems....More


The NATO Support and Procurement Agency (NSPA) is the NATO's logistics management structure. The NSPA is the executive body of the NATO Support and Procurement Organisation (NSPO), of which all NATO nations are members. The AC/135 has signed a Memorandum of Understanding (MoU) with NSPA for the provision of specific technical and administrative support...More

Codification (Cataloguing) is a uniform and disciplined process which examines Items of Production from Manufacturers, compares the technical and functional characteristics of each item, and where these are found to be identical, allocates a unique 13-digit NATO Stock Number to each Item of Supply.

  • To establish a common supply language throughout all logistics operations;
  • To enable interoperability of materiel;
  • To optimise resource management by avoiding duplication in inventories;
  • To facilitate master data management and enhance data quality.

The NCS applies two basic rules:

  • that each item of supply will have a single unique number ONE ITEM - ONE NUMBER;
  • that the National Codification Bureau (NCB) of the producing nation codifies the items of supply produced by that nation, regardless of which nation is the end user. This applies even if the producer nation does not use the item.

The NATO Stock Number (NSN) code is the unique official label applied to an item of supply and uniformly used by logistic systems of NCS members. NSN is represented by a 13- digit number, which can be divided into 3 unique parts:


NATO Commercial and Government Entity Code (NCAGE) is a 5 character code assigned to each manufacturer and used mainly to record manufacturers' names against codified Items. More details in section... NCAGE

NCS Publications



The Allied Codification Publication No. 1 (ACodP-1) contains the basics of the NATO Codification System. The terms of reference and responsibilities of National Codification Bureaux, users and contractors are specifically defined therein. Every nation has the responsibility to implement ACodP-1 rules and procedures.



The multilingual NATO Master Catalogue of References for Logistics (NMCRL) represents the largest global logistic database, with over 18 million active NATO Stock Numbers (NSNs), 38.2 million manufacturer or vendor Reference (Part) Numbers and having over 29.5 million User Registrations.



Multilingual ACodP-2/3 online (public website) contains data on NATO Classification (the Multilingual NATO Classification structure of all groups and classes and their definitions - ACodP-2) and Item Names (Multilingual NATO IoS Name Directory - ACodP-3) with definitions in 20 different languages.

NCS - the Global Language of Logistics

NCS is based on principles and procedures described in following NATO Standardization Agreements (STANAGs):

  • STANAG 3150 : Codification – Uniform System of Supply Classification;
  • STANAG 3151 : Codification – Uniform System of Item Identification;
  • STANAG 4177 : Codification – Uniform System of Data Acquisition;
  • STANAG 4199 : Codification – Uniform System of Exchange of Materiel Management Data;
  • STANAG 4438 : Codification – Uniform System of Dissemination of Data Associated with NATO Stock Numbers (NSN).

These STANAGs are included in the NATO Manual on Codification - ACodP-1 - Chapter I.
