A National (or NATO) Item Identification Number (NIIN) is a 9-digit numeric code which uniquely identifies an item of supply in the NATO Codification System (NCS). As shown above, to form a National Stock Number (NSN), the NIIN is prefixed by the Federal Supply Class (FSC). However, the NIIN alone uniquely identifies the item, and the FSC merely adds context by indicating the general classification of the item. The NIIN is usually formatted with dashes, as follows 00-006-8046.
