NSN Look up

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.
