Make a list of when you think you obtained the savings bonds. You don't need an exact date, but an estimate will help. Your search will be eased by providing as much information as possible.
Make a list of your previous addresses. Match these addresses to the time during which you think you obtained the savings bonds.
Obtain your social security number. If you think that the bonds were purchased using a relative's social security number then try to obtain that number.
Write a letter to the Bureau of Public Debt requesting a list of bonds in your name. It is important to include the information you have obtained about your bonds, including when you think they were issued as well as your address at this time, your social security number; the name, address, and social security number of the person who gave you the bonds, and your current address. Include this information for each bond you are requesting.
Sign and mail the letter. It can take up to six weeks to get a response that will include a list of your bonds' serial numbers, values and series.
