NSN (National Stock Number)

Introduction

In the world of government contracting, the National Stock Number (NSN) plays a critical role in logistics, inventory management, and procurement processes. This unique identifier streamlines the acquisition of products for the Department of Defense (DoD) and other federal agencies. In this article, we’ll discuss the definition of an NSN, provide examples, answer some frequently asked questions, and conclude with the importance of NSNs in government contracting.

Definition

The National Stock Number (NSN), formerly known as the Federal Stock Number (FSN), is a 13-digit alphanumeric code assigned to items of supply that are procured, stored, and issued through the federal supply system. The NSN is used to categorize and identify items in inventory, ensuring that they can be easily recognized and ordered by government agencies.

Key Components of an NSN

• FSN Prefix: The first four digits identify the Federal Supply Classification (FSC), which defines the category of the item.
• Item Identification Number: The next group of digits provides a unique identifier for the item within that category.
• Check Digit: The final digit serves as a verification tool to ensure the number is accurate.

Examples

To better understand the concept of an NSN, here are a few examples of items along with their respective NSNs:

1. 1-2332-0003 - This NSN might refer to a specific type of screw or fastener commonly used in military equipment.
2. 7-4444-0005 - An NSN for a designated piece of electronic equipment.
3. 8-2121-0012 - This could signify a certain type of protective clothing for military personnel.
