Jump to navigation Jump to search

Federation Supply Group (FSG) is a component of the Federation Stock Number (FSN), the 14-digit alphanumeric identifier within the Starfleet Codification System to identify specific items of supply.

A supply group identifies a basic category and a relatively homogeneous area of items and constitute a related grouping for supply management purposes.


The supply group, identified by the purple call-out in the diagram above, signifies the classification of an item. Together with its Federation Supply Class, identified by the red call-out, they signify the Federation Supply Classification Group (FSCG) that the item belongs in. The FSCG is the first portion of the of three main sections—the others being the Codification Bureau code prefix, and the Starfleet Item Identification Number (SIIN)—to form a unique FSN for a specific item of supply.
