The 

National/NATO

Stock Number

A National/NATO Stock Number 

(NSN) is simply an of�icial label 

applied to an Item that has been 

cataloged in the Federal Cataloging 

System (FCS) or NATO Codi�ication 

System (NCS).

The NSN consist of 13-digit code, 

composed of 4-digit Federal/NATO 

Supply Classi�ication (FSC/NSC), 

the 9-digit National/NATO Item 

Identi�ication Number (NIIN) is 

composed of a 2-digit NATO Code 

for the National Codi�ication 

Bureau (NCB), plus a 7-digit nonsigni�icant number assigned by the 

individual NCB.

During the NSN assignment, a wide 

range of logistics data is assembled 

to de�ine the Item of Supply. This 

information includes the Item 

Name, Manufacturer’s Reference 

Number, Unit Price, Characteristics, 

Shelf-Life and information 

associated with the Acquisition all 

the way to the Disposition of the 

Item of Supply.

Federal Logistics Information System (FLIS) data is unrestricted 

information for each NSN in the FCS. FLIS forms the foundation for all 

logistics information systems and is the catalog of more than sixteen 

million Items of Supply used by the U.S. Government and international 

partners. Below are resources that can be used to extract FLIS data.

Federal Logistics (FED LOG®)

FED LOG® provides users the ability to access and query FLIS data during 

instances when internet connectivity is not available. FED LOG® provides 

essential information about items of supply to include the NSN, Approved Item 

Name, Manufacturers and Distributor information, to include Part Numbers, 

Freight Data, Hazardous Materiel Indicators, Interchangeable and Substitution 

data, Acquisition Advice Code (AAC) and Unit Price, Physical and Performance 

Characteristics along with service speci�ic management data. FED LOG® is 

available for download by .mil or .gov customers with NIPRNET access via 

FedMall. For more information visit: https://www.dla.mil/InformationOperations/Services/Applications/FED-LOG/

Web Federal Logistics Information System (WebFLIS®)

WebFLIS® is a tool that provides essential information about supply items 

including the NSN, the item name and company data (including part numbers), 

through a web interface connected to FLIS data. This information is primarily 

used by DLA, military services, and United States Government sponsored 

contractors doing business with the U.S. Government. WebFLIS® data is updated 

multiple times a day. WebFLIS® has additional tabs such as Advanced 

Characteristics Search, Medical, Weapon System and a Bill of Material 

(BOM)/Sets, Kits and Out�its (SKO) to allow users to narrow down searches 

using speci�ic �iltering and clear text supply codes with the ability to translate.

Public Logistics (PUB LOG®)

PUB LOG® is intended for use by the public who require National Stock Number 

(NSN) and other publicly releasable cataloging information including Federal 

Supply Classi�ication (FSC) data and Commercial and Government Entity (CAGE) 

codes. PUB LOG® can be downloaded from the FLIS Electronic (e) Reading room. 

Updated products with complete datasets are uploaded on the �irst of every 

month. All proprietary data and service unique data on the NSN is excluded. Most 

public and contractor requirements are satis�ied through PUB LOG® tool and the 

download contains both the classic version and the new, user friendly “IMD2” 

version. Contractors that require FED LOG® data are able to download from 

FedMall if they have a CAC and access to the government NIPRNet.
