Quickly search, cross-reference, and procure critical aerospace and defense components using precise 13-digit National Stock Numbers (NSNs), including high-demand parts such as 5305000056451, 5306000065805, 1560000178457, and 5935000223655. Aerospace Buying, an ASAP Semiconductor platform, connects NSNs with 9-digit National Item Identification Numbers (NIINs), Federal Supply Classes (FSCs), CAGE Codes, and Manufacturer Part Numbers (MPNs) through a real-time database to simplify procurement.
What Is an NSN Part Number?
A National Stock Number (NSN) is a standardized 13-digit code used by NATO member nations and defense agencies to catalog supply items. The first four digits represent the Federal Supply Class (FSC), which identifies the product group. The remaining nine digits form the National Item Identification Number (NIIN), which uniquely identifies the specific physical part. Together, this structure enables accurate inventory tracking, cross-referencing, and logistics management across international defense and aviation supply chains.
