How Do You Get a UEI Number?

Find out how to get a Unique Entity ID in SAM.gov, when validation happens first, and how UEI-only differs from full registration.

Direct answer

To get a UEI number, use SAM.gov's entity Get Started flow and choose the Unique Entity ID option if you only need the identifier. SAM.gov says UEI-only requires the entity's legal business name and physical address. If you want to bid on federal contracts or apply directly for federal assistance, continue into full SAM registration instead.

legal business name + physical address + UEI-only choice = Unique Entity ID path

UEI issuance is not active registration

A Unique Entity ID identifies the entity. It does not by itself mean the entity has an active SAM registration for contracts or assistance.
