How an NSN is Structured
Every 13-digit NSN is divided into systematic segments that reveal vital information about the part's classification and nation of origin:
$$\underbrace{\mathbf{5995}}_{\text{FSC}}-\underbrace{\mathbf{01}-\mathbf{366}-\mathbf{3703}}_{\text{NIIN}}$$
Federal Supply Class (FSC): The first 4 digits categorize the item by commodity type (e.g., 5995 represents cable, cord, and wire assemblies).
National Item Identification Number (NIIN): The remaining 9 digits uniquely identify the item:
National Codification Bureau (NCB) Code: The first 2 digits of the NIIN designate the assigning country (e.g., 00 or 01 for the United States, 99 for the United Kingdom).
Sequential Item Identifier: The final 7 digits form a non-significant serial number for the precise hardware item.

Frequently Asked Questions (NSN Procurement FAQ)
What is the difference between an NSN and a NIIN?
An NSN (National Stock Number) is a 13-digit code that includes the 4-digit Federal Supply Class (FSC). A NIIN (National Item Identification Number) consists of only the last 9 digits of the NSN, uniquely identifying the specific item regardless of changes in classification.
How do I search for parts using a CAGE Code?
You can enter any 5-digit CAGE (Commercial and Government Entity) Code directly into our lookup tool to view all cataloged NSN parts manufactured or supplied by that specific entity.
Are all parts shipped with full trace and documentation?
Yes. Every component shipped by ASAP Aero Supplies undergoes strict quality assurance and is delivered with manufacturer certifications, lot trace documentation, and compliance paperwork as requested.
