NSN lookup
A National Stock Number is a 13-digit identifier the U.S. and NATO supply systems use to identify items of supply. PartsPerk accepts NSN, NIIN, FSC, and CAGE inputs and routes each to the right doorway. Add quantity, condition, needed date, and document needs to send a clean RFQ to aviation parts suppliers.
Keep letters in a manufacturer part number. For example, 9169M40P177 is a part number, not NIIN 916940177. An NSN has 13 digits; a NIIN has nine. Search results are reference information; confirm availability and technical eligibility with the supplier.
Identifier structure source: Defense Logistics Agency NSN guidance. The cataloging bureau code does not establish the country of manufacture.
Open the canonical doorway for any NSN, FSC group, or CAGE code. Each doorway carries a breadcrumb, neutral aviation context, and an RFQ entry — you do not have to know the part number to start.
RFQ checklist
A clear request gets a clear quote. Add these fields when you send a request — most fields are optional but the more you provide, the faster the right aviation parts source can reply.
FAQ
A National Stock Number (NSN) is a 13-digit identifier for an item of supply. It consists of a four-digit Federal Supply Class (FSC) and a nine-digit National Item Identification Number (NIIN). An NSN is not a manufacturer part number or evidence of aircraft installation eligibility.
The NIIN is the last nine digits of the NSN — a unique item number worldwide. The first four digits of the NSN are the FSC (Federal Supply Class). PartsPerk accepts NSN, NIIN, and FSC inputs and routes each to the right doorway.
Type the 13-digit NSN into the search bar. PartsPerk routes you to the canonical NSN doorway with item name, FSC, NIIN, related part numbers, and CAGE-coded suppliers. If no exact match is held in the index, the page captures an RFQ with the NSN attached.
Yes. Paste or upload a list of NSNs in your RFQ — PartsPerk packages a single quote request across the list. Add quantity, condition, needed date, and document needs to speed up supplier reply.
No. PartsPerk does not claim live inventory or airworthiness. The NSN doorway shows neutral identifiers, FSC context, and supplier candidates for buyer review. Availability and trace are confirmed with the supplier before any order moves forward.
Available part-number references are candidates for review. A shared NSN or a search match does not establish an approved alternate. Verify the manufacturer reference, applicable technical data and operator requirements before selecting a replacement.
Paste a list of NSNs into the RFQ and PartsPerk packages a single request across the list. Add quantity, condition, urgency, and document needs to get clean replies from the right aviation parts suppliers.
