Do I still need a DUNS number?

No. The DUNS number was retired in April 2022 and replaced by the Unique Entity ID (UEI) assigned in SAM.gov.

The federal government stopped using the Dun & Bradstreet DUNS number in April 2022. Its replacement is the Unique Entity ID (UEI), a 12-character code assigned directly in SAM.gov at no cost.

If a form or portal still asks for a DUNS number, the UEI is what it now expects. You do not need to request a DUNS number to do business with the federal government.
