CAGE codes provide a standardized method of identifying a given facility at a specific location.
CAGE codes are referenced in various databases of the NCS, where they are used along with the supplier's part number to form a reference which is held on the National Stock Number (NSN) record.
This reference enables users of the NCS to determine who supplies any given part.
In the NCS metadata, the CAGE code's Data Record Number (DRN) is 9250 (or 4140 for NSCM); information listed under this DRN identifies very specifically the semantics of CAGE, its syntax, and the procedures associated with it.
[3] There is no meaning encoded in the code itself, other than the underlying NCB; it is simply a unique identifier.
