Vendor Registration

Vendors wishing to do business with ORNL must be registered in SAM (System for Award Management) and maintain their registration annually. Registration is free. Visit to register.

To register in SAM, you will need a D-U-N-S number:

Please note that a D-U-N-S number is a unique nine digit identification number that is assigned for ‘each’ physical location of your business. The address on your D-U-N-S record must match the address we have on our supplier database for you.
