NSN Look up

With a plethora of parts available in the aerospace and defense industries, it is of utmost importance that there is a solid and orderly structure for how parts are categorized for the ease of buyers, distributors, and beyond. An NSN, NATO stock number, or national stock number are the various names for the 13 digit numerical code that categorizes various parts and is a system recognized by all NATO countries.

The first four digits of the NSN are made up of the FSG and FSC, both being 2 digits each. These 4 digits work together to denote which group and class the part belongs to depending on the commodity type. The remaining 9 digits are the NIIN, or national item identification number. The first 2 digits of the NIIN represent the NATO country code who first coded the item. The remaining 7 digits of the NIIN have no major significance and help further sort the manufactured part.
