(a) This part applies to a Federal agency's Federal financial assistance as defined in § 25.400. This part applies to all applicants for and recipients of Federal financial assistance unless exempted by Federal statute or § 25.110.

(b) Subrecipients are required to obtain a UEI in accordance with subpart C. This part does not apply to subrecipients of subrecipients (second-tier subrecipients) or contractors under Federal awards.

(c) This part does not apply to an individual who applies for or receives Federal financial assistance as a natural person (unrelated to any business or nonprofit organization an individual owns or operates).

(d) Because this part applies to loan guarantees and other guaranteed programs, recipients of the guarantee from the Federal agency (for example, lenders of guaranteed loans) are required to complete entity validations and acquire a UEI. Additionally, at the Federal agency's discretion, non-individual beneficiary borrowers (for example, small businesses or corporations) may be required by the Federal agency to obtain a UEI or register in SAM.gov.
