What is a CAGE code?
A CAGE (Commercial and Government Entity) code is a 5-character code that identifies a company, plant or government activity. U.S. codes are assigned by the Defense Logistics Agency; companies outside the U.S. get an NCAGE code from their national codification bureau. In the federal catalog, every manufacturer part number is paired with the CAGE code of the company that makes or controls it.
Why suppliers need one
U.S. companies get a CAGE code when they register in SAM.gov to do business with the federal government. Foreign suppliers need an NCAGE code to be listed as a source in NATO catalogs.
CAGE codes and NSNs
An NSN lists the part numbers that meet its description, each with a CAGE code. Searching by CAGE code shows every NSN where that company is a listed source, which is how buyers find approved sources and suppliers find opportunities.
