Browse NSN Parts List

National Stock Numbers, or NSNs, refer to 13 digit numerical codes that are given to standardized materials of supply by NATO countries as an effort to establish identification and categorization of parts. NSN numbers are recognized by all NATO countries, including those outside of NATO such as Japan, Australia, and New Zealand. The first four digits of the NSN refer to the Federal Supply Classification Group which are used to group items together that provide a similar functionality. The next 9 digits are the National Identification Number (NIIN), with the first two digits of this code denoting the country that first codified the item. Meanwhile, the final 7 digits are a string that uniquely identifies that item, not holding any inherent meaning other than for categorization.
