The serial number is printed on the front of your bond, usually in the upper right corner

Every savings bond has a unique serial number — a string of letters and numbers that identifies that specific bond. On a paper bond, you'll find it printed in the upper right area of the front side, though the exact placement varies slightly depending on the bond type and when it was issued. The number is typically printed in a larger font than other text on the bond, making it relatively easy to spot once you know where to look.

If you own a bond electronically through TreasuryDirect (the U.S. Treasury's online system), the serial number appears in your account dashboard. You don't need to search a physical document — you can view it by logging in, selecting the bond, and looking at its details page.

Key Takeaways

  • Paper bonds display the serial number in the upper right corner of the front side, printed larger than surrounding text.
  • Electronic bonds held in TreasuryDirect show the serial number in your online account under each bond's details.
  • The serial number is a unique identifier you may need when redeeming the bond or reporting it lost or stolen.
  • If you cannot locate the serial number on a paper bond, contact the Treasury or your financial institution for help retrieving it.

Why you need the serial number

The serial number serves as proof of ownership and identity for your specific bond. When you redeem a bond — whether at a bank or through TreasuryDirect — you may be asked to provide it. If a bond is lost, stolen, or damaged, the serial number helps the Treasury locate your bond in their records and process a replacement.

You'll also need the serial number if you're reporting a bond as missing or if you're trying to verify information about a bond someone gave you. Banks sometimes request it when you're cashing in a bond in person, though many institutions can look it up if you provide other details like the issue date and denomination.

How to read a paper bond's serial number

On a physical savings bond, the serial number typically appears as a combination of letters and numbers. For Series EE bonds, it's usually printed clearly on the front. For older bonds or other series, the format may differ slightly, but it will always be a unique identifier specific to that one bond.

The serial number is distinct from the denomination (the face value of the bond) and the issue date, which also appear on the bond. Make sure you're copying the serial number itself and not another number printed on the document. If the print is faded or unclear, you can contact the Treasury Department or the bank where you plan to redeem it — they can help you identify it.

Finding the serial number in TreasuryDirect

If you own bonds through TreasuryDirect, log into your account at treasurydirect.gov using your username and password. Once you're logged in, navigate to "My Account" or "Manage My Securities," depending on the current layout of the site.

Select the specific bond you need information about. The details page will display the serial number along with other information like the purchase date, current value, and maturity date. You can take a screenshot, write it down, or print the page for your records.

What to do if you can't find the serial number

If you have a paper bond and the serial number is illegible or missing, don't assume the bond is unusable. Contact the Treasury Department's Bureau of the Fiscal Service at 1-844-284-2676 or visit treasurydirect.gov to report the issue. You'll need to provide other identifying information about the bond, such as the series, denomination, and issue date.

Your bank may also be able to help. When you bring a bond in to redeem it, the teller can often look up the serial number in the Treasury's system using the bond's other details. If the bond is damaged but the serial number is still partially visible, bring it in anyway — the bank staff are experienced in reading worn bonds.

Keeping your serial number safe

Write down or photograph the serial number of each bond you own and store the list somewhere secure — separate from the bonds themselves. This is especially important for paper bonds. If a bond is lost or stolen, having the serial number recorded makes it much easier to report and replace.

For electronic bonds in TreasuryDirect, you don't need to manually record the serial number since it's always available in your online account. However, keeping a written or printed list of all your bonds and their serial numbers is still a good practice for your personal records.

Frequently Asked Questions

Is the serial number the same as the bond's denomination?

No. The denomination is the face value of the bond (for example, $50 or $100), while the serial number is a unique identifier. Both appear on the bond, but they serve different purposes. The serial number identifies that specific bond; the denomination tells you its value.

Can I redeem a bond without the serial number?

Yes, in most cases. Banks and the Treasury can look up a bond using other information like the series, issue date, and denomination. However, having the serial number makes the process faster and reduces the chance of confusion if you own multiple bonds.

What if my paper bond is too old to have a serial number?

All U.S. savings bonds have serial numbers. If you have an extremely old bond and cannot locate the serial number, contact the Treasury Department — they maintain records of all bonds ever issued and can help you identify it.

Do I need the serial number to check my bond's current value?

In TreasuryDirect, you can view all your bonds and their values by logging into your account — you don't need to manually enter serial numbers. If you're checking the value of a paper bond at a bank, the teller may ask for it, but can usually look it up without it.
