All Vendors are required to have a Unique Entity Identifier to enter into a contract with IWTSD and the unique entity identifier used in SAM.gov has changed.
On April 4, 2022, the unique entity identifier used across the federal government changed from the DUNS Number to the Unique Entity ID (generated by SAM.gov).
For more information about this transition, visit SAM.gov or the Federal Service Desk, FSD.gov. You can search for help at FSD any time or request help from an FSD agent Monday–Friday 8 a.m. to 8 p.m. ET.
