The National Item Identification Number consists of how many digits that identifies each item of supply used by the Department of Defense?

The National Item Identification Number (NIIN) is a crucial part of the system used by the Department of Defense for inventory management and supply chain efficiency. The NIIN is a 9-digit number that uniquely identifies each item of supply. It is part of the broader system known as the Federal Supply Classification. The NIIN is typically found within the 13-digit National Stock Number (NSN), which consists of the first two digits representing the Federal Supply Group, the following three digits representing the Federal Supply Class, and the last nine digits being the NIIN itself.

Understanding the NIIN's structure is important for properly identifying and managing military supplies, ensuring that there is accurate tracking and accountability throughout the logistics chain. This unique identification helps in preventing confusion among similar items and facilitates efficient stock management.
