From Banks and Other Financial Institutions
You can buy I Bonds from most banks, credit unions, or savings institutions. These
institutions accept funds and purchase orders and forward the order to
a Federal Reserve Bank where the bonds are issued and mailed according
to your instructions.
Through TreasuryDirect
I-Bonds may be purchased through TreasuryDirect. After opening a TreasuryDirect
account online, you can buy, manage, and redeem electronic EE and I Bonds
over the Internet.
From a Bond-A-Month Program
Many financial institutions offer I Bonds through "Bond-A-Month" savings plans.
This plan allows you to automatically buy bonds on a regular schedule
(not necessarily monthly). Contact your financial institution for more
information.
Through a Payroll Savings Plan
I Bonds can be purchased through the Payroll Savings Plan offered by many employers.
Check with your employer to see if the plan is offered where you work.
