31 U.S.C. § 3327: General authority to issue checks and other drafts

The Secretary of the Treasury may issue a check or other draft on public money in the Treasury to pay an obligation of the United States Government. When the Secretary decides it is convenient to a public creditor and in the public interest, the Secretary may designate a depositary to issue a check or other draft on public money held by the depositary to pay an obligation of the Government. As directed by the Secretary, each depositary shall report to the Secretary on public money paid and received by the depositary. The Secretary of the Treasury shall take such actions as are necessary to ensure that Social Security account numbers (including derivatives of such numbers) are not visible on or through unopened mailings of checks or other drafts described in subsection (a) of this section. The amendments made by this Act [amending this section] shall apply with respect to all mailings of checks or other drafts issued on or after the date which is 3 years after the date of the enactment of this Act [ Nov. 6, 2000 ]. Effective on the date of the enactment of this Act, the Secretary of the Treasury shall commence procedures to gradually implement the amendments made by this Act in advance of the effective date described in subsection (a). Not later than 1 year after the date of the enactment of this Act, and annually thereafter for each of the next 2 years, the Secretary shall transmit to each House of the Congress a report describing the manner and extent to which the requirements of the preceding sentence have been carried out.”
