The Federal Government will transition away from from DUNS number to the New Unique Entity Identifier (UEI) on April 4, 2022. This will not affect the 2022-2023 CDBG funding cycle and all current organizations with a DUNS number will be sent their new UEI by the Federal government. No action by current DUNS registered organizations needs to take place. For 2023-2024 CDBG applications, the UEI will be required. More information on the transition can be found on the GSA website.
