How many numbers are in an NSN?

Explanation:
NSN is a 13-digit numeric code. It’s made up of two parts: the first four digits are the Federal Supply Classification that groups the item by type, and the remaining nine digits form the National Item Identification Number that uniquely identifies the specific item within that group. So the total length is 13 digits.
