Unique Entity Identifier Update
What is a Unique Entity Identifier?
A Unique Entity Identifier (UEI) is a unique number assigned to all entities (public and private companies, individuals, institutions, or organizations) who register to do business with the federal government. This page contains more information about UEIs.
Government Transition from DUNS Number to New Unique Entity Identifier Extended
By April of 2022, the federal government will stop using the DUNS number to uniquely identify entities registered in the System for Award Management (SAM). At that point, entities doing business with the federal government will use a unique entity identifier (UEI) created in SAM.gov. They will no longer have to go to a third-party website to obtain their identifier. Active registrants will have their UEI assigned and viewable within SAM.gov; there is no action for registered entities to take at this time. This transition allows GSA to streamline the entity identification and validation process, making it easier and less burdensome for entities to do business with the federal government.

What Action Do I Need to Take?
Users are not required to take any action at this time. The IAE has shifted the UEI transition date from December 2020 to April of 2022.
