The U.S. Department of Defense created the National Stock Number system in order to create a uniform naming system for all the components that are sourced, stocked, and procured within the federal supply system. NSNs are 13 digit serial numbers that classify and describe an item. Within the NSN are the smaller classification numbers, Federal Supply Group, Federal Supply Class, country code, and National Item Identification Number. Typically in the format, XXXX-XX-XXXXXXX, the first two digits of the NSN are the Federal Supply Group. The following two digits are the Federal Supply Class. The FSG and the FSC can be referenced in the Department of Defense’s H2 handbook.
