How many digits does a NIIN contain?

A National Item Identification Number (NIIN) is designed to identify a specific item in the supply system and has a total of 9 digits. The first two digits of the NIIN are usually derived from the Federal Supply Classification (FSC) grouping and are intended to categorize the type of item. The remaining seven digits provide a unique identifier for the item itself. This structure ensures standardized identification across various military and logistical operations. Understanding the composition of the NIIN is essential for ensuring accurate item management and logistics within defense and military contexts.
