What is a National Stock Number?
The National Stock Number or commonly referred to as an NSN in the USA is used to identify supply materials that are standardized and approved by the NATO countries.
Another name for an NSN is a NATO stock number; it is a 13 digit code in which countries use NSN under the NATO standardization agreement. All countries in the treaty use NATO stock numbers. The NSN catalog consists of over 7.5 million different active items. And over 20 million different part numbers under various manufactures.
Federal Supply Group (FSG) is identify by the first two digits. The broad category in which the item belongs.
National Item Identification Number (NIIN) is the last 9 positions and identify the specific item.
The first two positions of the NIIN identify the NATO country code for the country making the number assignment.
The last seven digits of the NIIN are the item serial number.
The serial number does not follow an assignment pattern. it is merely a number for the item. A National Item Identification Number (NIIN) is a nine-digit code that identifies each item of supply. A National Stock Number (NSN) is a 13-digit number consisting of the four-digit Federal Supply Class (FSC) and the nine-digit NIIN.
The United States Department of Defense is also a part of the groups that use the NSN to purchase various supplies and materials they consume often. Countries that use NSN’s but are not members of the treaty include countries such as Japan and New Zealand. The UK uses Domestic Management Code.
