The NSN can be further broken down into smaller subcategories, each providing individual information about the component. To begin, the first four digits of the NSN are known as the Federal Supply Classification Group. The FSCG determines which of the 645 subclasses an item belongs to. The FSCG is further split into the Federal Supply Group (FSG) and the Federal Supply Classification (FSC). The FSG is made up of the first two digits of the NSN which determines which of the 78 groups an item belongs to. The second 2 digits make up the FSC, which determines the subclass an item belongs to. In the aerospace industry a key federal supply group is FSG 15: Aircraft and Airframe Structural Components. The remaining 9 digits are made up of the 2-digit country identifier followed by the 7 National Item Identification Number (NIIN). The US for example,  has the country identifier, 00.
