NICN (Navy Item Control Number) is a temporary number assigned by the Navy to identify parts in the Navy supply system before they are cataloged by the Defense Logistics Services Center (DLSC) and given a complete National Stock Number (NSN).
The cognizant item managers review the temporary NICNs periodically to convert them to NSN or to delete the ones that are no longer required. The SPCC is responsible for maintaining NICN to NSN cross-reference list (formerly FMSO’s responsibility). For activities that use FED-LOG, searching by NICN to view the associated NSN is one of the options that can be used during technical research.
