A National Stock Number (NSN) is a 13-digit numeric code assigned by the United States Department of Defense (DoD) to identify a specific item of supply. NSNs are used to track inventory, manage procurement, and facilitate logistics. They are essential for ensuring that the right items are delivered to the right place at the right time.
To apply for a NSN, you must first determine if your item is eligible. Only items that are used by the DoD or its contractors are eligible for NSNs. Once you have determined that your item is eligible, you can submit an application to the Defense Logistics Agency (DLA). The DLA will review your application and, if approved, will assign a NSN to your item.
