RNVC Codes
Reference Number Variation Codes (RNVC) specify whether the part number is defining or non-defining for an Item of Supply - NATO Stock Number (NSN). NATO defines an order of preference for RNVC for NSNs to be used for all new procurement. The order of preference is determined in conjunction with the RNCC for a NSN. The table below defines the meaning of each RNCC / RNVC combination in order of declining preference for procurement.
RNVC code definitions are maintained in the document, NATO ACodP-1 Manual, and the FEDERAL LOGISTICS INFORMATION SYSTEM - FLIS PROCEDURES MANUAL MULTIPLE APPLICATION REFERENCES/INSTRUCTIONS/TABLES AND GRIDS, DoD 4100.39-M Volume 10.
RNVC Code Table
| RNVC | Description |
|---|---|
| 1 | A design control reference or other reference number that does not identify an item of production without the use of additional information, or is either a specification, part, type or similar reference number that does not identify an item of supply without the use of additional information. |
| 2 | A design control reference or other reference number that is an item-identifying number for an item of production, or is either a source control reference, a specification or a standard part, type, or similar reference number that is an item-identifying number for an item of supply. |
| 3 | A vendor's reference (part) number on a source control item, as defined in ASMEY-14.24M and ASMEY-14.100M, which is reparable through the removal, exchange, and reinstallation of component parts. The related source control document number will also reflect Code 3. This code is limited to a type 1B or 4B item identification. |
| 8 | A non-item-identifying reference number that is added to a replacement NSN as a result of a cancel-use action on a NSN recorded with ISC 3 or E. It is used to identify the original item of supply/replaced item. This reference number is automatically moved and this code is automatically assigned, do not submit for cataloging purposes. |
| 9 | A reference number which was the Design Control Reference for the item of supply concept (Original Design Activity) that is now inactive coded Reference Number Category Code (RNCC) 3; a specification, standard, or other reference number which is superseded, cancelled, obsolete or discontinued and is coded RNCC 5; a reference number for information only coded RNCC 6; a drawing which is the Single Controlling Reference Number (SCRN) coded RNCC 2 or 7; or a drawing number reference coded RNCC D. |
RNCC / RNVC Combinations
In Order of Declining Preference for Procurement. This allows a buyer to select the most appropriate source for a NATO Stock Number.
| RNCC Code | RNVC Code | Explanation |
|---|---|---|
| 1 | 2 | An Item Identifying, Source Control Reference Number (Reference Number). Along with the Source Control Reference Number, FLIS edits require that at least one additional Reference Number with a RNCC 3/RNVC 2 shall also be recorded on the item. |
| 1 | 3 | A Reparable Source Control Reference Number, which is Item Identifying. FLIS edits require that only one additional RNCC 3/RNVC 3 be recorded on the NSN. |
| 7 | 2 | A Vendor Item Drawing (VID) number, which is Item Identifying. VID numbers are administrative control numbers and shall not be used as a part identification number. FLIS edits require that there must also be at least one RNCC 3/RNVC 2 vendor reference numbers assigned. |
| 2 | 2 | A Definitive Reference Number developed from a Government Specification or Standard which, is Item Identifying. |
| 2 | 9 | A Government Specification/Standard, No Longer Active. |
| 3 | 2 | The Primary Reference Number, which is Item Identifying, assigned by a manufacturer, professional association or standard designator to identify an item of production. For Service applications, sometimes referred to as the primary buy. |
| 3 | 3 | The Primary vendor Reference Number on a Source Control item, which is Item Identifying and Reparable, assigned by a manufacturer, professional association or standard designator to an item of production. |
| 3 | 9 | Original Design Activity reference number, no longer procurable from this CAGE. |
| 7 | 9 | A Vendor Item/Specification Control Drawing, No Longer Valid. |
| 5 | 2 | A Secondary Reference Number, which is, Item Identifying. For Service applications, sometimes referred to as the secondary buy. |
| 5 | 3 | The Secondary vendor Reference Number on a Source Control item, which is Item Identifying, reparable assigned by a manufacture, professional association or standard designator to an item of production. |
| 8 | 2 | A US/NATO Reproduced Item Identification Number, which is Item-Identifying, representing a production item reproduced with authorization to use NATO/NSN and is same item as the original. |
| 2 | 1 | A Non-definitive, Reference Number developed from a Government Specification or Standard which, is Non-Item Identifying, |
| 4 | 1 | A Non-Definitive Reference Number derived from a Government Specification or Standard. Additional information such as type, class, grade, style, size, and material is required to fully identify the item. |
| 3 | 1 | The Primary Reference Number, which is Non-Item Identifying, assigned by a manufacturer, professional association or standard designator to an item of production. |
| 7 | 1 | A VID number which is Non-Item Identifying. Refer to Cataloging Data Standards and Transactions Volume 10, Table 8, Valid Reference Number Combinations for Item of Supply Concept, for FLIS edit criteria. |
| 5 | 1 | A Secondary Reference Number, which is Non-Item Identifying. |
| 6 | 9 | DoD Ammunition Code, Production Equipment Code, or NATO Informative Reference. |
| D | 9 | Identifies a drawing or other document related to an Item of Supply for informational purposes only, but is not used in item of supply determinations. Envelope drawings, next higher assembly drawings or parts. |
| 8 | 1 | A US/NATO Reproduced Item Identification Number, which is Non-Item Identifying, representing a production item reproduced with authorization to use NATO/NSN and is same item as the original. |
| A | 2 | A Design Category Packaging and Related Logistics Data Reference Number, which is Item Identifying, representing the number of a document for packaging and related logistics data requirements. |
| A | 1 | A Design Category Packaging and Related Logistics Data Reference Number, which is Non-Item Identifying, representing the number of a document for packaging and related logistics data requirements. |
| 5 | 9 | A Reference Number that has been canceled as obsolete or superseded and is retained for informational purposes only (audit trail, visibility and tracking purposes). |
| C | 1 | A Reference Number that is used as an Advisory Reference only. It is not used in the item of supply concept. The Reference Number does not have a direct relationship with the NSN other than as a service/agency decision. |
| E | 8 | A Reference Number which has transferred to the replacement NSN as a result of a cancel-use action of an NSN that was in a standardization relationship (ISC 3 or E). |
