According to the U.S. Treasury Department, 25,000 bond payments are returned each year to the department as undeliverable.
Also, “billions of dollars in savings bonds” that have stopped earning interest continue to go un-cashed.
As a result, the agency created “Treasury Hunt,” a website to help consumers learn about those savings bonds “no longer earning interest.”
Individuals who may be particularly interested in the website include those with Legacy Treasury Direct payments or HH/H interest who are not receiving interest payments, and those who own or know of “a deceased loved one” who owned savings bonds or Treasury notes/bonds that have matured.
The service, located at www.treasuryhunt.gov, has limitations.
The site does not contain records of all savings bonds (only information on Series E bonds issued after 1974 and Series EE bonds issued since 1980).
The site “may not completely identify any/all savings bonds you may have lost … only those that have reached final maturity and were issued in 1974 and after.”
While you cannot search for undeliverable bonds, the site does provide information on filing a claim for bonds.
Another route to determining if savings bonds are no longer earning interest is to find the issue date for bonds and visit the “Treasury Securities that Have Stopped Earning Interest” website (available through a link at Treasury Hunt).
