National Stock Number (NSN)
The Federal Stock Number (FSN) was an 11-Digit Numeric Code developed by the US Department of Defense in 1949 to identify items in the Army-Navy Catalog System. In 1974, the FSN was replaced with the National Stock Number (NSN) by simply adding two digits to the 11-Digit Code in positions 5 and 6 to signify the country of origin of the Numeric Code. In the instance of the USA, this code was 00. This enabled NATO Members to adopt the coding system while maintaining track of the NSNs created by that member.
The 13-digit unique NSN code is assigned to an item of supply that is repeatedly stocked, stored and issued throughout the federal supply system. It’s assigned at the request of the military services, certain federal or civilian agencies and foreign friendly countries.
The NSN is officially recognized by the United States Government, the North Atlantic Treaty Organization (NATO) and many other Governments around the world. Government Agencies, including the US Department of Defense (DOD) and NATO, use the NSN to buy and manage billions of dollars worth of supplies annually. Currently, there are over 17 Million Active NSNs in the NSN Catalog and more than 10 Million Historical NSNs that are no longer actively used. Together, these NSNs represent more than 42 Million Manufacturer’s Part Numbers from more than 2.6 Million Suppliers.
NATO Stock Number
As the coding system has been adopted by the member nations of NATO, and other non-member nations as well, the system has come to be known as the NATO Stock Number, although the term National Stock Number has stuck in the USA. Now, both National Stock Number and NATO Stock Number are interchangeable terms for the same Codification System.
