In an effort to streamline the federal supply chain process, the US government has put a standardized classification system into place, known as the National Stock Number or NATO Stock Number internationally, that categorizes all parts that are in use or have been used in the past. The Defense Logistics Agency, the agency in the US Department of Defense responsible for providing all logistical support to the US armed forces, is tasked with assigning and classifying parts using a 13-digit item identifying number. A National Stock Number consists of the following parts:
The Federal Supply Classification Group (FSCG) is further subcategorized into the Federal Supply Group (FSG), and the Federal Supply Code (FSC), which are the first and last 2-digits of the FSCG, respectively. The FSG is more general while the FSC is more specific. The NIIN is broken down into the NCB (National Codification Bureau), the first 2 digits, and the Item Serial Number, which is the last 7 digits. The NCB is simply the NATO country code while the Item Serial Number is a unique item identifying number.
