Since the federal supply chain is so vast and complex, it is necessary to have a classification system in place to organize and keep track of all parts that are in use or have been previously used by the US government. The Defense Logistics Agency, the agency in the US Department of Defense that provides logistical support to all US military branches, is responsible for this classification system, known as the National Stock Number (NSN). The National Stock Number system, or NATO Stock Number as it is known internationally, is a system that uniquely identifies all parts using a 13-digit number, which is broken down into the following parts:
1. Federal Supply Classification Group- first 4 digits of the NSN (known as the FSCG)
2. National Item Identification Number- last 9 digits of the NSN (known as the NIIN)
The Federal Supply Classification Group is further broken down into 2 more specific parts, the Federal Supply Group (FSG) and the Federal Supply Code (FSC), which are the first and last 2 digits of the FSCG, respectively. The National Item Identification Number includes a National Codification Bureau (NCB), which indicates the NATO country code, and an Item Serial Number, a unique 7-digit number that is specific to every part.
