Explore FSC & FSG Codes for NSN Parts
Federal Supply Classes (FSCs) and Federal Supply Groups (FSGs) provide a standardized system for organizing millions of items used by the United States government. By categorizing components based on physical and functional characteristics, these codes simplify inventory management and procurement across various sectors and allied nations.
At Buy National Stock Numbers, we offer a complete FSC catalog where each class is organized under its corresponding FSG. This setup allows you to browse efficiently and locate the parts you need quickly. You can also use the number buttons at the top of the page to filter FSGs and FSCs by their first digit. Clicking on an FSC will take you to a detailed catalog of in-stock part numbers ready for procurement.
Understanding FSCs and FSGs
FSCs and FSGs are essential tools for government and commercial procurement teams. They help identify components accurately, reduce errors in ordering, and streamline inventory planning. Whether you are sourcing resistors, connectors, or hardware, knowing the correct FSC or FSG ensures you receive the exact parts required for your projects or maintenance tasks.
