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 https://sam.gov/ to register.

To register in SAM, you will need a D-U-N-S number: https://fedgov.dnb.com/webform/

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.
