A DUNS number (Dun & Bradstreet number) is a unique nine-digit number that is used to identify your organization when registering for sites such as FedConnect and SAM.gov. If you are unsure of what your DUNS number is, please ask your senior management for assistance, or locate the number on your SAM.gov account.

If your organization does not have a DUNS number, you may request one for free at http://fedgov.dnb.com/webform. For more information regarding the DUNS number, you may visit the DUNS website at https://www.dnb.com/. There is also additional information available on the SAM.gov website.
