NSN Lookup

National Stock Numbers, or NATO Stock Numbers, are thirteen-digit numerical codes used by the United States Department of Defense and all members of the North Atlantic Treaty Organization to catalog and organize parts and items commercially bought and sold.

The first four numbers denote the item’s Federal Supply Classification Group, the general “family” of items the particular part belongs to, such as computer components, automobile parts, etc. The nine-digit National Item Identification Number denotes the item’s country of origin, and assigns a unique numeric identifier to the item.
