The entity will need to contact Dun & Bradstreet (D&B) at firstname.lastname@example.org indicating the old and new DUNS numbers. A D&B associate will respond by verifying the correct DUNS number for the organization. If D&B confirms the change, it will send the new DUNS number to SAM. SAM will then update their registration to reflect the new DUNS number. Note: only active registrations will be updated in SAM.
Registration in SAM and Dun & Bradstreet (DUNS) is free. There are businesses that provide services to entities to register or update SAM and DUNS. These businesses charge a fee for their services. They are not part of the federal registration process and entities do not have to use them. If an entity believes it should not have been charged for the services it received, the Department of Interior is not able to assist directly. The applicant should seek a refund from the company itself, or contact agencies such as the Better Business Bureau for further assistance.
