3 - Design Control Reference

Reference Number Category Code (DRN_2910)


Design Control Reference. The primary number used to identify an item of production or a range of items of production, by the manufacturer (individual, company, firm, corporation, or Government activity) which controls the design, characteristics, and production of the item by means of its engineering drawings, specifications and inspection requirements.

5 - Replaced / Discontinued

Reference Number Category Code (DRN_2910)


Secondary Reference. Any additional number, other than a primary number (codes 1,2,3,4) informative reference (code 6) or vendor item drawing reference (code 7) assigned to an item of production or supply by a commercial or Government organization, which represents the same item of production or supply to which the National Stock Number (NSN) was assigned. The reference number may have had an RNCC of 1, 2, 3, 4 or 7 but has since been replaced in the item-of-supply concept of the NSN by another primary number.

C - Advisory Reference

Reference Number Category Code (DRN_2910)


Advisory Reference. A number assigned to an item of production or supply not included in the item-of-supply concept to which the NSN has been assigned (e.g., an item that may have been used in the preproduction equipment design which has since been redesigned or replaced). Use of this RNCC is restricted to conditions where cross-reference is required to establish identification to an item of supply. Additionally, there is not direct relationship of the reference number to the NSN other than a Service/Agency individual decision. (RNCC shall be used only in conjunction with RNVC 1.
