How many digits does an NSN contain?

• A. 13 digits
• B. 11 digits
• C. 12 digits
• D. 10 digits

Answer: (A)

An NSN is a 13-digit code used to uniquely identify items in the DoD supply system. It’s built from two parts: the first four digits are the Federal Supply Classification (FSC), which groups items by type, and the remaining nine digits form the National Item Identification Number (NIIN), which identifies the specific item (including country of origin information). When you combine the 4-digit FSC with the 9-digit NIIN, you get 13 digits in total. That’s why 13 digits is the correct count. The shorter options don’t fit the established NSN structure.
