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.

What is Happening?

New Unique Entity Identifiers will be automatically assigned to entities registered in SAM at a future date.

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 a future, to-be-determined date.
