What is the National Item Identification Number (NIIN)?

The National Item Identification Number (NIIN) is indeed a nine-digit number that forms part of the National Stock Number (NSN). The first four digits of the NSN represent the Federal Supply Classification (FSC), while the last nine digits are the NIIN that uniquely identify a specific item in the supply system. This allows for efficient tracking and inventory management of military and government supplies, ensuring that items can be easily located and requisitioned as needed.

The significance of the NIIN lies in its role in logistics and inventory management. It helps ensure that every item is distinctly classified, facilitating easier procurement, distribution, and management across the military’s complex supply chain. By having a standardized identification system, it minimizes the chance of misidentification and helps maintain the accuracy of records relating to items in service.
