What to Do If You Lost a Series I Savings Bond

Losing a Series I savings bond can produce the same sinking feeling as losing cashfollowed by the slightly embarrassing realization that the bond was last seen in an envelope labeled “important stuff.” Fortunately, a missing paper I bond is not the same thing as missing money. Savings bonds are registered to their owners, so the U.S. Treasury can usually identify the bond and provide relief after ownership has been verified.

The recovery process is not instant, however. You may need to reconstruct old purchase information, open a TreasuryDirect account, complete FS Form 1048, have your signature certified, and wait while the Bureau of the Fiscal Service searches its records. Current TreasuryDirect notices warn that searches for lost, stolen, or missing savings bonds may take 11 months or longer. In other words, this is paperwork, not pizza delivery.

This guide explains exactly what to do if you lost a Series I savings bond, including how to search for matured bonds, what information Treasury needs, whether to request payment or an electronic replacement, and how to avoid delays.

First, Determine What You Actually Lost

A missing paper I bond

FS Form 1048 is intended primarily for a paper savings bond that was lost, stolen, destroyed, mutilated, or never received. Paper Series I bonds were once sold through banks, payroll savings programs, and federal income tax refunds. As of January 1, 2025, new I bonds are available only electronically through TreasuryDirect, although previously issued paper bonds remain valid.

You might therefore have a paper I bond that was purchased years ago, received as a childhood gift, ordered with a tax refund, inherited from a relative, or tucked into a filing cabinet by someone who believed filing cabinets were immortal.

A TreasuryDirect account you cannot access

An electronic I bond cannot be physically lost because Treasury maintains the ownership record online. If the bond appears to be “missing” because you forgot your TreasuryDirect account number, password, security answers, or associated email address, start with TreasuryDirect login assistance rather than FS Form 1048.

Do not create a duplicate account simply because the first one is difficult to access. Contact TreasuryDirect if the automated recovery tools do not work, especially when your name, address, or banking information has changed.

A bond you believe existed but cannot identify

This situation is common with childhood gifts. You may remember an aunt announcing that she bought you “one of those government bonds,” but nobody remembers the denomination, issue date, or location. You can still submit a claim, although Treasury needs enough information to locate the ownership record.

Do Not Rely on Outdated Treasury Hunt Instructions

Many older financial articles tell readers to use Treasury Hunt. That advice is now outdated. TreasuryDirect retired the Treasury Hunt search tool on September 30, 2025. Inquiries concerning matured, unredeemed Treasury securities are now handled through state unclaimed-property programs. TreasuryDirect directs consumers to the National Association of Unclaimed Property Administrators, or NAUPA, to find the appropriate state office.

Search the official unclaimed-property program for every state where the owner or original purchaser may have lived. NAUPA also provides access to a multistate search service, and searches through official state programs are free. Be wary of companies demanding an upfront fee merely to tell you that unclaimed money exists.

A state search is most useful for a bond that has matured and remains unredeemed. It does not replace FS Form 1048 when you know that a specific paper bond was lost, stolen, or destroyed before or after maturity.

Gather Every Detail You Can Find

The more information you provide, the easier it is for Treasury to distinguish your bond from millions of other savings-bond records. Start a small recovery file and collect documents before filling out the form.

Useful information includes:

• The bond’s serial number, if available
• The exact issue month and year or a reasonable range of dates
• The face amount and number of missing bonds
• The full legal names printed on the bond
• Middle names or initials used at the time of purchase
• The owner’s Social Security number
• The address printed on the bond
• The purchaser’s Social Security number if the bond was a gift
• Details about where and when the bond was last seen
• A police, insurance, or disaster report, when applicable

Treasury’s instructions state that when the serial number is unavailable, the claimant should provide the specific month and year of purchase, the complete Social Security number, the names shown on the bond, and the address associated with it. That means a missing serial number is inconvenient, but it is not automatically the end of the road.

Search old tax returns, gift letters, bank statements, payroll records, safe-deposit-box inventories, estate documents, scanned photographs, and family emails. A blurry photo of Grandma holding the bond may not belong in the Smithsonian, but it might reveal a denomination or issue date.

Complete FS Form 1048

The official document is FS Form 1048, Claim for Lost, Stolen, or Destroyed United States Savings Bonds. Use the current edition from TreasuryDirect rather than a copy saved years ago. The form was revised in March 2026 at the time this article was prepared.

Part 1: Describe the missing bonds

List the issue date, face amount, serial number, registration, Social Security number, names, and address for each bond. If several bonds are missing, attach an additional sheet or FS Form 3500. Clearly state how many bonds are involved.

Do not invent precise information merely because the form has a precise-looking box. When an issue date is uncertain, provide an honest date range and explain what you know.

Part 2: Explain the loss

Indicate whether the bonds were lost, stolen, or destroyed. Describe when the loss was discovered, who last had the bonds, where they were stored, and when they were last seen. If identification documents disappeared at the same time, disclose that as requested.

Attach a copy of a police report when one was filed. If the bonds were destroyed or mutilated, carefully package and submit any surviving pieces as directed by the form. Do not tape together charred fragments as though you are auditioning for a forensic-drama spinoff.

Part 3: Establish your authority

A person named on the bond can generally file the claim. A parent, guardian, conservator, executor, administrator, trustee, or other legal representative may also be able to apply, but additional evidence of authority may be required.

A court-appointed representative may need to submit a court certificate or certified letters of appointment under court seal. The current form specifies that certain appointment evidence must be dated within one year of submission.

Part 4: Address bonds owned by minors

When a minor is named on the bond, the form asks for the child’s name, date of birth, Social Security number, living arrangement, source of support, and information about the parents. The person completing the claim depends on the child’s competency, custody situation, and whether a court-appointed guardian exists. Follow the instructions carefully rather than assuming that one parent’s signature is always sufficient.

Choose an Electronic Replacement or Cash Payment

FS Form 1048 gives an eligible Series I bond owner two primary choices: receive a substitute electronic bond or request payment by direct deposit. Treasury no longer reissues Series I bonds on paper.

Option 1: Request an electronic substitute bond

Choose replacement when you want to keep the bond until a later redemption date. You will need a TreasuryDirect account and must provide the account number, account name, and associated Social Security number or Employer Identification Number.

The replacement bond continues in electronic form. It does not become a brand-new investment with a new purchase date. After it appears in your account, you may be able to add a secondary owner or beneficiary according to TreasuryDirect’s registration rules.

Replacement may be attractive when the bond is still earning interest and you do not need the money. Series I bonds earn for as long as 30 years unless redeemed earlier.

Option 2: Request payment by direct deposit

Choose payment when you want to redeem the bond. The form requires the payee’s taxpayer identification number, the bank-account name, a nine-digit routing number, the account number, the account type, and the financial institution’s information.

Ordinarily, an I bond cannot be redeemed during its first 12 months. A redemption before five years also forfeits the most recent three months of interest. After five years, the early-redemption penalty no longer applies.

If a substitute bond is requested when the original is within one full calendar month of final maturityor has already maturedTreasury may issue payment instead. Likewise, an otherwise ineligible bond that is less than one year old may be replaced electronically rather than cashed.

Get Every Required Signature Certified

Do not sign FS Form 1048 at your kitchen table before visiting the certifying official. Each required signer must sign in the presence of a notary or an authorized certifying officer and establish identity to that person’s satisfaction.

Authorized certification may be available at a bank, credit union, trust company, or notary office. Call ahead because not every branch employee is authorized to apply the required seal or stamp. Bring current government-issued identification and the unsigned form.

The form accepts specified notarial seals, financial-institution stamps, signature guarantees, and approved Medallion-program stamps. An incomplete certification, missing seal, or signature dated before the appointment can send the package on an unwanted round trip.

Mail the Claim to the Correct Address

Unless the form or Treasury gives different instructions, mail the completed package to:

Include the certified form and all required supporting documents. If a person named on the bond has died, Treasury generally requires a certified copy of the official death certificate. Legal evidence and other documents submitted with the claim may not be returned, so retain copies of everything you send.

Consider using a trackable mailing service and keep the tracking receipt with your duplicate claim file. Write down the date mailed, the bonds covered, and the relief requested. This simple record becomes valuable when processing lasts many months.

What Happens After You Submit the Claim?

Treasury reviews the information and searches its registration records. It may contact you for clarification, additional forms, proof of identity, estate documentation, or evidence supporting your authority to act.

Processing times vary, but TreasuryDirect currently advises that searches for lost, stolen, or missing bonds may require 11 months or longer. Avoid sending duplicate claims merely because several weeks have passed. Duplicate packages can create confusion rather than speed.

You can contact TreasuryDirect at 844-284-2676 during its published weekday service hours. Keep your mailing date and claim details nearby when calling, but never send sensitive personal information in response to an unsolicited email.

What If You Find the Original Bond Later?

Once Treasury replaces or pays a missing bond, the original certificate becomes property of the United States. You cannot cash both the replacement and the rediscovered paper bond. Doing so would be less “lucky attic discovery” and more “federal problem.”

If the original turns up after relief has been granted, return it to Treasury Retail Securities Services at the Minneapolis mailing address. The claimant’s certification also obligates the signer to surrender the original and, when required, repay losses caused by an improper redemption.

Special Situations

The bond was lost in a federally declared disaster

Treasury offers special procedures for owners affected by an officially declared disaster. A claimant may be instructed to write “DISASTER” at the top of FS Form 1048 and on the envelope. Treasury may waive the normal one-year holding requirement and prioritize the request. Follow the current disaster instructions because the abbreviated filing requirements differ from an ordinary claim.

The registered owner has died

The surviving co-owner, beneficiary, executor, administrator, or voluntary representative may have authority to handle the claim, depending on the bond registration and estate status. A death certificate and additional estate forms may be necessary. TreasuryDirect provides separate instructions for administered and non-administered estates.

The bond was stolen with personal identification

File a police report, monitor financial accounts, and consider placing fraud alerts or credit freezes when Social Security cards, tax documents, or other sensitive records were stolen with the bond. Describe the theft accurately on FS Form 1048 and attach the report when applicable.

You receive an email offering to recover the bond for a fee

Use only official government channels. Treasury states that it does not send unsolicited messages asking for personal or financial information or demand fees to release funds. Confirm that you are using the official TreasuryDirect website before entering account information.

Tax Consequences of Receiving Payment

Replacing a lost bond with an electronic substitute does not ordinarily create the same tax result as redeeming it. However, registration changes that remove a living owner or principal co-owner can create reporting consequences, so complicated ownership changes deserve professional tax advice.

When a Series I bond is redeemed, previously unreported interest is generally included in federal taxable income for that year. Savings-bond interest is exempt from state and local income tax. Some taxpayers may qualify to exclude interest when eligible bonds are used for qualified higher-education expenses and all statutory requirements are met.

Keep the payment statement and any Form 1099-INT with your tax records. When an estate, trust, co-owner, or beneficiary is involved, ask a qualified tax professional who is responsible for reporting the accumulated interest.

How to Prevent Another Lost-Bond Adventure

Once the claim is resolved, build a simple bond inventory. Record the series, issue date, face amount, serial number, registration, TreasuryDirect account number, and beneficiary information. Keep the inventory separate from the paper certificates so one flood, fire, burglary, or enthusiastic decluttering session cannot erase both.

The Treasury savings-bond calculator can estimate the value of paper bonds using the series, denomination, and issue date. It does not verify ownership or confirm that a serial number is valid, but it is useful for maintaining an updated inventory.

For existing paper I bonds, consider converting them to electronic form through TreasuryDirect before they disappear. Electronic ownership eliminates the physical-certificate problem, although you should still maintain secure records for the online account.

Recovery Experiences and Practical Lessons

Experience 1: The childhood bond with no serial number

A common claimant remembers receiving bonds from grandparents but has no certificates or serial numbers. The first instinct is often to assume recovery is impossible. A better approach is to reconstruct the purchase window. Old birthday cards, photographs, tax records, and conversations with relatives may establish that the bonds were purchased every December between 2012 and 2016.

The practical lesson is to provide a specific, honest date range and every variation of the owner’s name and address. A complete Social Security number, former address, approximate issue dates, and purchaser information can be more useful than a wild guess at a serial number.

Experience 2: The bond lost during a move

Another familiar story begins with three carefully labeled moving boxes and ends with 47 boxes labeled “misc.” The owner knows the certificate was stored with tax returns but cannot determine whether it was discarded, misplaced, or left behind.

In this case, documenting the last known location matters. The claimant should state when the move occurred, who handled the files, the address from which the bond disappeared, and when the loss was discovered. A calm factual explanation is more valuable than a dramatic essay titled “The Betrayal of the Moving Company.”

Experience 3: The flood-damaged bond

Disaster claims often involve a certificate that is not technically missing but is soaked, moldy, burned, contaminated, or unreadable. Owners sometimes throw away the remains immediately. That can be a mistake because Treasury may instruct claimants to preserve or submit surviving pieces, depending on the situation.

The lesson is to photograph the damage, protect the fragments, follow the current disaster instructions, and clearly mark the form and envelope when Treasury directs you to use the disaster procedure. Do not risk your health handling contaminated documents; ask Treasury how to proceed when the bond is unsafe.

Experience 4: The inherited bond nobody knew existed

Estate recovery becomes complicated when a family discovers an old bond inventory but not the certificates. The bond may name a surviving co-owner, a beneficiary, or only the deceased owner. Each registration creates different rights.

The most useful first step is not arguing over who “should” receive the money. It is identifying the exact registration, locating death certificates and court papers, and determining whether the estate is formally administered. Treasury may request additional forms after reviewing the initial claim, so organized records and patience are essential.

Experience 5: The claimant who checks the mailbox every day

Perhaps the most universal experience is waiting. A claimant mails a perfect package on Monday and begins wondering about it by Friday. Current search times can extend beyond 11 months, especially when Treasury must identify bonds without serial numbers.

The lesson is to retain a complete copy, use tracking, note the mailing date, respond quickly to requests for additional documentation, and avoid repeatedly filing the same claim. Slow processing is frustrating, but duplicate paperwork is unlikely to transform a government search into a Formula One pit stop.

Ultimately, losing a Series I savings bond is usually a record-recovery problem rather than a permanent financial loss. Gather accurate details, use the latest FS Form 1048, obtain proper certification, choose payment or electronic replacement thoughtfully, and prepare for a long processing period. The certificate may have vanished, but the registered ownership record is what gives the bond its value.

Note: Treasury forms, processing times, tax rules, and estate requirements can change. Verify the current FS Form 1048 and TreasuryDirect instructions before mailing a claim. This article provides general educational information and is not individualized legal, investment, or tax advice.
