NATO Stock Number

A NATO Stock Number (NSN) is simply an official label applied to an item of supply. The NATO Codification System (NCS) is a uniform and common system for the identification, classification and stock numbering of items of supply.

Objectives of the NCS include:
- Facilitate interoperability between user nations
- Increase the effectiveness of user nation's logistics systems
- Minimize logistics costs of user nations
- Facilitate data handling

The NSN is recognized by the United States government, the North Atlantic Treaty Organization (NATO), and many international partners around the world.

One Item - One Stock Number

NATO Master Catalogue of Reference for Logistics
The multilingual NATO Master Catalogue of References for Logistics (NMCRL) exists as a real time database on the Internet (NMCRL-WEB) and as an offline database for use on any computer not connected to the Internet NMCRLOFFLINE). As the primary logistics tool for NATO and AC/135 sponsored countries, the NMCRL provides a catalogue of the materiel they use. NMCRL is a database containing all NSNs worldwide and varies from the FED LOG product which consists mainly of United States National Stock Numbers (NSNs) and those NSNs used by the United States. FED LOG; however, contains more information in comparison to NMCRL (e.g. management data, prices, etc.). Only a small number of the countries share their management data via NMCRL. The majority of NATO Codification System countries (i.e. NATO and AC/135 sponsored countries) do not exchange that data internationally.
