Attachment No 08 - UEI for BID.pdf

This attachment provides guidance on Unique Entity Identifier (UEI) numbers for federal contract registration. Effective April 4, 2022, SAM.gov transitioned from using DUNS Numbers to a new 12-character alphanumeric Unique Entity ID generated by SAM.gov. Contractors are required to include both DUNS and UEI numbers in their bid package. Existing registered entities can find their Unique Entity ID through SAM.gov, while new entities can obtain their ID during the entity registration process. The document emphasizes that entity registration, searching, and data entry now require use of the new Unique Entity ID.
