National Stock Number

What is NSN?

National Stock Number (NSN) is a unique identification code used in logistics to categorize and track items within the supply chain. It is a standardized system that enables efficient management of inventory and simplifies the process of procurement and distribution.

The NSN is a 13-digit numeric code that provides a universal identification for items across different organizations and countries. It consists of four distinct parts: the Federal Supply Group (FSG), the Federal Supply Class (FSC), the National Item Identification Number (NIIN), and the Check Digit.

The FSG is the first two digits of the NSN and represents the broad category or functional area of the item. For example, FSG 10 represents weapons, while FSG 70 represents information technology equipment.

The FSC is the next two digits and further narrows down the classification of the item within the FSG. It provides more specific information about the item's purpose or characteristics. For instance, FSC 10 represents firearms, while FSC 20 represents ammunition and explosives.

The NIIN is the following nine digits and serves as a unique identifier for each item within the FSC. It distinguishes one item from another, even if they belong to the same FSG and FSC. This ensures precise identification and tracking of individual items throughout their lifecycle.

The Check Digit is the last digit of the NSN and is used for error detection. It is calculated based on the previous 12 digits using a specific algorithm. The check digit helps verify the accuracy of the NSN and prevents errors during data entry or transmission.

The NSN plays a crucial role in logistics operations, particularly in military and government supply chains. It facilitates the standardization of item identification, simplifies inventory management, and enhances interoperability between different organizations. By using NSNs, logistics professionals can quickly locate and procure the required items, reducing lead times and improving overall efficiency.

Moreover, the NSN system enables effective cataloging, storage, and retrieval of information related to items. It allows for the creation of comprehensive databases that contain detailed specifications, maintenance procedures, and other essential data. This information can be easily accessed and shared, ensuring accurate and timely decision-making.

In conclusion, the National Stock Number (NSN) is a standardized identification code used in logistics to categorize and track items within the supply chain. It consists of four parts: the Federal Supply Group (FSG), the Federal Supply Class (FSC), the National Item Identification Number (NIIN), and the Check Digit. The NSN system enhances inventory management, simplifies procurement, and improves interoperability. It is an essential tool for logistics professionals, enabling efficient and effective supply chain operations.
