Last modified: April 3, 2025

The National Stock Number (NSN) generator creates standardized, unique identification numbers for managing and cataloging supply items in military, government, and industry logistics systems.

The National Stock Number (NSN) or NATO Stock Number comprises a 13-digit stock number. It comprises the four-digit Federal Supply Classification (FSC) and the nine-digit National Item Identification Number (NIIN). The NIIN consists of a two-digit National Codification Bureau (NCB) number followed by a seven-digit item number.
