NATO CODIFICATION SYSTEM (NCS)

horizontal rule

The NCS applies two basic rules:

bulletthat each item of supply will have a single unique number
(ONE ITEM - ONE NUMBER)
bulletthat the National Codification Bureau (NCB) of the producing nation
codifies the items of supply produced by that nation, regardless of
which nation is the end user. This applies even if the producer nation
does not use the item.

Group & Class Item Name Code & Item Name Characteristics Data Management Data Manufacturers

List of items of production complying with the item of supply concept - NATO Commercial and Governmental Entity Code (NCAGE) and respective reference number. Various codes are associated with these references:

bulletReference Number Variation code (RNVC)
indicating whether the cited Reference Number is or is not item
identifying or is for information only;
bulletReference Number Category Code (RNCC)
specifying the type of reference = part number, standard reference,
technical drawing reference number, etc;
bulletDocument Availability Code (DAC)
designating the current status of technical documentation availability
bulletReference Number Action Activity Code (RNAAC)
identifying the codifier responsible for the codification;
bulletReference Number Status Code (RNSC)
indicating the admissibility of the reference for procurement; and a
bulletMajor Organisational Entity Code (MOE - Code)
identifying the users of the item of supply : 
YB = SPAIN; YJ = SINGAPORE; etc....

Each Group covers a series of related Classes 
Each Class covers a relatively homogeneous area of commodities, with respect to their physical or performance characteristics, or with respect that the items included therein are such that they are usually requisitioned or issued together or constitute a related grouping for supply management purposes.
