31 C.F.R. § 363.138 How do I purchase a certificate of indebtedness?
Title 31 - Money and Finance: Treasury
You may purchase your certificate of indebtedness through one or more of the following four methods: (a) payroll deduction, in which your employer sends funds through the ACH method to your TreasuryDirect® account; (b) deposit by your financial institution, in which your financial institution sends funds by the ACH method to your TreasuryDirect account on a recurring or one-time basis; (c) through the Buy Direct® function of your TreasuryDirect account, in which you direct us to debit funds from your account at a financial institution to purchase a certificate of indebtedness. This method is limited to an amount no greater than $1000 per transaction. When you use the Buy Direct function to debit funds to purchase all or a portion of a certificate of indebtedness, you will not be permitted to schedule a redemption for cash from your certificate of indebtedness within five business days after the date of the debit entry; or (d) by using the proceeds from the redemption or interest payment of a security to purchase a certificate of indebtedness.
