The NSN, Nato Stock Number, is a 13 digit code structured as 4 sets of numbers - a set of four, followed by a set of two then a set of followed by a set of four, like this:

1111-22-333-4444

The first four digits (1111 above) define the 'Federal Supply Class' - i.e. The Product.

The next two digits (22 above) define the country of origin.

The next seven digits (333-4444 above) are a unique number defining the exact size.


A real example is:
4710-99-923-8641

This is decoded as follows:

4710 = Pipe, tube, and rigid tubing - Including Culvert Pipes; Culvert Pipe Connector Bands; Metallic Pipes; Plastic Pipes; Tubes and Rigid Tubing and their assemblies.

99 = UK Manufacture
923-8641 = 0.25inch O/D x 0.049 inch Wall Thickness
