The fastest way to find all your 401(k) accounts is the Department of Labor’s Retirement Savings Lost and Found database at lostandfound.dol.gov, which links retirement plans to your Social Security number. But that single search won’t catch everything. Old accounts can end up with former employers’ plan administrators, default rollover IRAs you never knew about, the Pension Benefit Guaranty Corporation, or even a state unclaimed property office. A thorough search means checking several places.
Start With the DOL Lost and Found Database
The Retirement Savings Lost and Found database was created under the SECURE 2.0 Act of 2022 and is run by the Department of Labor’s Employee Benefits Security Administration. It covers 401(k)s and other defined-contribution plans, along with defined-benefit pension plans, from private-sector employers and unions. It does not cover IRAs, government plans, or certain religious organization plans.
To use it, you need a verified Login.gov account, which requires your legal name, date of birth, Social Security number, a mobile device, and photos of a valid driver’s license. Once verified, you enter your Social Security number and the system returns a list of retirement plans linked to it, along with contact information for the plan administrators. A result doesn’t guarantee you still have money waiting. It only confirms you participated in a plan at some point. The administrator can tell you whether a balance remains, was already paid out, or was rolled over somewhere else.
If you have trouble reaching an employer or union listed in your results, call the DOL’s benefits advisors at 1-866-444-3272 or submit a request at AskEBSA.dol.gov. They can help you track down the right contact.
Check for Accounts From Closed or Bankrupt Employers
When a company goes out of business or terminates its retirement plan, benefits sometimes get transferred to the Pension Benefit Guaranty Corporation under its Missing Participants Program. The PBGC maintains a searchable database of unclaimed benefits at pbgc.gov. Start there, and if your former employer’s plan name appears, call 1-800-400-7242 and tell the representative you’re calling about a missing participants (MP) benefit. They’ll verify your identity, look up your records, and mail you details about any benefit owed.
Some terminated plans purchased annuities from insurance companies instead of transferring money to the PBGC. The PBGC keeps a separate list of these “notification plans” that includes the insurance company’s name, address, and the annuity contract number. If your plan is on that list, you’ll contact the insurance company directly with the contract number to claim your benefit.
Look Up Your Former Employer’s Plan Filing
Every employer that sponsors a retirement plan must file an annual Form 5500 with the federal government, and those filings are public. The DOL’s EFAST2 system at efast.dol.gov lets you search by company name to find the most recent filing. The form lists the plan’s current administrator, trustee, and recordkeeper (the financial company that actually holds the accounts). This is especially useful when your old employer was acquired, merged, or changed its plan provider. Even if the company name on your old statement no longer exists, searching the original name can lead you to the current entity managing the plan’s assets.
Once you find the recordkeeper, contact them with your name, Social Security number, and approximate dates of employment. They can confirm whether you still have an account.
Track Down Default Rollover IRAs
If you left a job and never told the plan what to do with your balance, your former employer may have pushed the money out without your involvement. Plans can force out balances of $7,000 or less (a threshold that increased from $5,000 in January 2024). Balances of $1,000 or less can be mailed to you as a check. Balances between $1,000 and $7,000 are typically rolled into a default IRA at a bank, trust company, or other regulated institution, often called an “automatic rollover IRA.”
These default IRAs are required to be invested conservatively, usually in a money market fund or stable value product designed to preserve principal. That means the money is safe but growing very slowly, and it may be quietly losing ground to inflation and maintenance fees. The institution holding the IRA is supposed to send you disclosures, but if your address changed, those notices may never have reached you.
Finding these accounts is tricky because there’s no single registry of default IRAs. Your best leads are the plan administrator (who can tell you where the rollover was sent) and the Form 5500 filing for the plan, which sometimes names the default rollover provider. You can also search your name on your state’s unclaimed property website, since very small balances ($1,000 or less) from missing participants can sometimes be transferred to a state unclaimed property fund.
Search State Unclaimed Property Offices
Federal law (ERISA) generally prevents states from seizing assets held inside private retirement plans. But there are two exceptions. When a plan is terminating and the administrator can’t find a participant after a diligent search, the money can be sent to the participant’s last known state of residence as unclaimed property. The same can happen with small balances of $1,000 or less in ongoing plans when the participant can’t be located.
Most states participate in a free multi-state search at missingmoney.com, or you can go directly to each state’s unclaimed property website. Search every state where you’ve lived or worked, since the transfer goes to the state of your last known address on file with the plan, which may not be where you live now. Claims are free to file, and you should never pay a third-party “finder” an upfront fee to search for you.
Review Your Own Records
Before diving into databases, check what you already have. Old pay stubs, tax returns, and W-2 forms list employer names and can jog your memory about jobs you may have forgotten. If you ever received a Form 1099-R (which reports retirement distributions or rollovers), it names the institution that sent the money and where it went. Annual benefit statements from plan administrators, even outdated ones, include account numbers and phone numbers that can start a paper trail.
Your Social Security statement at ssa.gov also lists every employer that reported wages under your Social Security number. Reviewing that history year by year is a reliable way to make sure you haven’t overlooked a short-term job where you might have been automatically enrolled in a 401(k).
Consolidate What You Find
Once you’ve located all your accounts, consider rolling them into a single IRA or your current employer’s 401(k) if the plan accepts incoming rollovers. Consolidating makes it easier to manage your investments, reduces the chance of losing track of money again, and eliminates multiple sets of maintenance fees. Request a direct rollover (trustee to trustee) rather than having a check sent to you, which avoids mandatory tax withholding and the 60-day deadline to redeposit the funds.
If an old account holds employer stock or has special features like access to institutional-class funds with very low fees, it may be worth leaving in place. But for most people, fewer accounts means better visibility and simpler retirement planning.
