DLA have announced changes for WebFLIS In 2014
 Originally scheduled for June 2014, the changes to WebFLIS are currently scheduled for November 2014

The Upcoming WebFLIS Change Notice reads as follows:

"Users of Public WebFLIS will be able to request Public data using the Freedom of Information Act (FOIA) or by visiting the FOIA Reading Room via a searchable product called PUB LOG FLIS Search. We will provide a link to PUB LOG FLIS Search and instructions when it becomes available so users can become familiar with it prior to the transition of Public WebFLIS. We value our customers and will make every effort to provide you with all the information needed to make this transition as transparent as possible."

"Upcoming WebFLIS improvements are projected for November 2014. WebFLIS will be changing and we want to prepare our customers. WebFLIS will move to a new platform and include several enhancements."

"The new application will only be accessible by controlled access such as Common Access Card (CAC) or External Certificate Authority (ECA). Current registered users will need to register/obtain roles through the Access Management and Provisioning System (AMPS). Pre-registration with AMPS will be available 30 days prior to going live. Please monitor this banner, we will update it when registration is actually open and provide instructions."

"Public WebFLIS will remain operational as WebFLIS transitions to the new platform. The future source for public Federal Logistics Information System (FLIS) data is the Freedom of Information Act (FOIA) reading room via an application called Public Logistics (PUB LOG) FLIS Search. PUB LOG FLIS search is now available at this site. Instructions for use of PUB LOG FLIS Search are provided in the FOIA reading room. We encourage non-CAC customers to access and utilize the PUB LOG FLIS Search and provide feedback."

"Customers who developed an automated process to query and download multiple items of supply from Public WebFLIS will not be able to retain this type of capability with PUB LOG FLIS Search. Since customers will be required to input a Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) when using PUB LOG FLIS Search, automated search processes will be restricted. When using PUB LOG FLIS Search, the customer will be able to view or download National Stock Numbers (NSNs), National Item Identification Numbers (NIINs), or a limited number of multiple part numbers within a single query."

"Authorized-DOD and DOD-Sponsored customers, who require larger volumes of information on a reoccurring basis, can obtain the information via a service from the FLIS Portfolio Data Warehouse. This is not intended for a one-time pull of data. This requires a system-to-system web service connection and data is delivered in XML format."

NSN Center Provides an Alternate Service to WebFLIS

NSN Center has been working hard to collect the data from the US Department of Defense as well as NATO and other publishing countries to provide a FREE NSN Lookup Service with advanced features which have not been available to the general public. NSN Center extends the WebFLIS data with pictures of the items, pricing, procurement information, commercial characteristics and additional technical characteristics. The system is published globally in multiple languages with official translations of fields and parameters where possible.

NSN Center incorporates much of the public data available from the NATO Master Cross-Reference Library (NMCRL) which is a paid subscription available from NATO. Much of the AC/135 database of NATO is available by Freedom of Information Requests and from the manufacturers of the products themselves allowing NSN Center to present this information augmented with pictures, pricing, sourcing information, commercial characteristics and technical characteristics.

The NSN databases provided by NSN Center are not simply a re-published version of the MCRL and NMCRL. NSN Center has built the database over more than 12 years and the database includes many corrections not implemented by NATO and many many Gigabytes of additional information which NATO do not augment their database with.
