After ASO has reviewed and consolidated the report, it is submitted to DLSC for screening for the applicable NSN. Upon assignment of the NSN, the superseding NSN is added to the NAC number. The superseded NAC number is deleted after two subsequent quarters. The NAC number consists of nine digits. The first two digits designated with LX is the NICN. The 3rd and 4th letters identify the specific naval activity. The reporting activity assigns Arabic numbers for the remaining five digits. Refer to FASOINST 4410.15F for a list of NAC designators and activities. The following example is a breakdown of a NAC number: LX-NQ-00001 LX - NQ - 00001 - Navy item control number NAC designator and activity Locally developed serial number for non-NSN item Requisitions for NAC-numbered items can be submitted directly to the reporting activity (identified by NAC designator) with an information copy to ASO. This is done when the requiring activity has verified that the material is available for issue. For deployed units, verification of material availability is not required. The requisition must be in the format described in FASOINST 4235,36 (series), Part Number Requisition and Follow-ups. The requisition must include remarks pertinent to NAC number, date, and person with whom the material availability was verified. PART NUMBER The part number, also called reference number, is an identification number assigned to an item by the manufacture. It is made up of letters, numbers, or combinations of both. When used with the CAGE code, it identifies the item. It is used with other technical data (for example, model, series, and end-use application) to requisition an item when an NSN is not assigned. Part number to NSN cross-reference is provided in FED-LOG, or any computers that contains C-MCRL information. Requisitioning procedures for part number requisition are described in FASOINST 4235.36 (series). COMMERCIAL AND GOVERNMENT ENTITY CODE The Commercial And Government Entity (CAGE) Code replaces the Federal Supply Code for Manufacturers (FSCM). The CAGE is a five-digit, numeric code assigned to different types of activities for identification. The CAGE for vendors who supply an item but do not manufacture it is identified by an alphabetic character in the second position; for example, 1B234. Other NATO manufacturers of items used in the U.S. supply system use CAGE with an alphabetic character in the first position; for example, K7654. The Cataloging Handbook H4 provides a list of CAGE codes and activity names. CAGE is also listed in the database for FED LOG users. SOURCES OF MATERIAL IDENTIFICATION This chapter presents different sources of information that is needed in performing technical research. Material identification does not end with the assignment of the NSN. Some means of identifying other particular needs by the stock number must be provided to the customers. This includes the means of determining the correct quantities of these items to carry in stock. Identification of needs maybe determined by using the lists described in the following paragraphs. MANAGEMENT LIST-CONSOLIDATED The Management-List Consolidated (ML-C) is a consolidated, cumulative listing of National Stock Numbers for all branches of the armed services. Each NSN is listed one time only. The integrated material manager and service or agency is listed separately. The ML-C is a tool used for determining management data applicable to items used or managed by other military activities. The ML-C information is included in Navy or DOD approved CD-ROM technical research publications. The information provided in the ML-C screen, when using CD-ROM, is described in the following text. Service/Agency Code The two-character Service/Agency (S/A) code identifies the service, agency, or activity. The codes are DA-Army, DF-Air Force, DM-Marine Corps, DN-Navy, DS-Defense Logistics Agency, GP-Coast Guard, TG-General Services Administration. Source of Supply The Source of Supply (SOS) column lists the routing identifier of the managing activity that is a potential source of supply. 3-11
