What is the difference between niin and nsn

During WWII, the military found it difficult to quickly and efficiently source parts from manufacturers as there was no formal naming system. A part could have multiple names depending on the manufacturer that made it.

This lack of a formal naming system led to inconsistencies in stock levels as there would be a surplus of components in one area and a deficit in another.

In response to these issues, the DoD set out to form a uniform system that could be understood across countries with language barriers. The key part of the NSN system is the digit identification number that is assigned to all components that are sourced, stocked, and procured within the federal supply chain. NSNs are made up various subcategories that each provide more information about the individual component.
