How to Find a Lost 401(k) or Pension After Changing Jobs

• Start with the Department of Labor’s Retirement Savings Lost and Found database for old private-sector 401(k) and pension plans, then confirm the result with the plan administrator.
• Use PBGC’s unclaimed-benefit search when a private employer’s pension or retirement plan ended, especially if the company closed, merged, or lost contact with you.
• Gather old pay stubs, W-2s, benefit statements, plan names, employer addresses, and name changes before contacting a former employer, PBGC, or the Department of Labor.

Start with the type of retirement plan you had

Finding retirement money from an old employer usually comes down to identifying where the account ended up. A 401(k) or similar defined-contribution plan normally has an individual account balance. A traditional pension, or defined-benefit plan, usually promises a future monthly payment or a lump sum based on a formula.

The best first step for most U.S. workers is the Department of Labor’s Retirement Savings Lost and Found database. It can show private-sector retirement plans connected to your Social Security number, including 401(k)-type plans and pension plans. A search result does not guarantee that money is still owed; the plan administrator must confirm whether the benefit was paid, rolled over, converted to an annuity, or remains available.

For plans that ended and transferred unclaimed benefits to the Pension Benefit Guaranty Corporation, or PBGC, use PBGC’s separate search. PBGC primarily handles certain terminated private-sector pension and retirement plans, not every old workplace account.

Search the Department of Labor database first

The DOL Retirement Savings Lost and Found database is designed to help workers reconnect with job-based retirement plans after changing jobs, an employer merger, or a business closure. It does not search individual IRAs, Social Security benefits, or most government retirement plans.

You will need to create or use a Login.gov account and complete identity verification. The current process requires a valid state-issued identification document or driver’s license, along with your Social Security number. Once you are verified, the database displays plan information and contact details when records are available.

Use the official database here:

Review every result carefully. Older records may contain a former employer name, an outdated address, or a previous plan administrator. Contact the administrator listed in the result and ask whether you have a vested benefit, where the assets are held, and what documents are required to claim or roll over the money.

Check PBGC if the plan ended

PBGC’s database is especially useful when a private-sector employer closed, a pension plan terminated, or a plan transferred unclaimed benefits for people the administrator could not locate. The search accepts your last name and the last four digits of your Social Security number.

PBGC’s search was most recently updated on August 5, 2026, and the agency says its database is updated quarterly. A match means PBGC may have a record connected to you, but it does not by itself prove that you are entitled to a payment.

Search the official PBGC database here:

PBGC’s Missing Participants Program can also involve plans that purchased an annuity from an insurance company rather than transferring money directly to PBGC. If you find your former plan on a PBGC notification list, the insurer or financial institution named in the record may be the organization that holds the benefit.

PBGC generally does not cover federal, state, city, or military pensions. It also does not provide individual account information for every type of retirement plan. If your old plan was a government plan, a union plan, or a plan that is still operating, you may need to contact the employer, union, plan administrator, or another government retirement system directly.

Contact the former employer or plan administrator

If neither database produces a useful result, go back to the source. Search your old paperwork for the plan name, employer identification number, recordkeeper, trustee, or third-party administrator. A plan may have changed names after a merger, so search both the old company name and any successor company.

Ask specifically for the retirement plan administrator, not only the company’s general human resources department. A useful request can include:

• Whether the employer-sponsored plan still exists
• Whether your account or pension benefit is still on the plan’s records
• Whether the plan merged into another plan
• Whether your balance was paid, rolled over, or transferred to an IRA or insurer
• What identification and claim forms are required
• Whether the plan can provide a Summary Plan Description or individual benefit statement

For a 401(k), ask the administrator to confirm the last known account balance and the date of any distribution. For a pension, ask whether you were vested and when you became eligible to begin payments.

If you cannot locate anyone

The Department of Labor’s Employee Benefits Security Administration can help with questions about lost or forgotten benefits in many private-sector retirement plans. A benefits adviser may also help identify a plan contact when the former employer or union is difficult to reach.

Use the official EBSA assistance page here:

EBSA’s benefits advisers can explain your options, but they may not be able to search the DOL Lost and Found database for you. You still need to complete the identity-verification process yourself when using that database.

What to do if the company went out of business

A closed company does not automatically mean your retirement money disappeared. A plan may have been taken over by a successor company, transferred to a financial institution, terminated through a formal process, or left without a reachable sponsor.

For an abandoned 401(k)-type plan, the plan’s bank, insurer, or other custodian may be authorized to wind it down and distribute benefits. The Department of Labor’s Abandoned Plan Program has a search tool that can show whether a plan is being terminated or has already been terminated, along with the qualified termination administrator handling the process.

Check the official Abandoned Plan Search through the Department of Labor program page:

If the company filed for bankruptcy, look for both the bankruptcy trustee and the retirement plan’s recordkeeper. The bankruptcy case may identify who is responsible for plan records, but it may not be the organization holding your account.

Gather these documents before you make a claim

Old records can make the difference between a quick confirmation and a long investigation. Collect as much of the following as you can:

• Old 401(k) statements or pension benefit statements
• Summary Plan Descriptions and enrollment materials
• Pay stubs showing retirement deductions
• W-2 forms from the years you worked there
• Letters about a merger, plan termination, or distribution
• The employer’s former and current names
• Your approximate employment dates and work location
• Records of any legal name changes or former addresses
• Tax forms showing a previous rollover or lump-sum payment

For a terminated defined-benefit pension, PBGC may ask for extensive employment information, tax returns from the year you left and the following year, and proof such as pay stubs or W-2 forms. The agency may also request a Social Security notice showing potential private retirement benefits or a letter from the former company confirming a vested benefit.

Know whether you are looking for a balance or a future pension

One common mistake is assuming that every old retirement account belongs in the PBGC search. PBGC mainly deals with certain private-sector plans that ended. The DOL database is broader for job-based plans, while a state unclaimed-property search may help if a financial institution transferred dormant assets to the state.

A practical order of operations

1. Search the DOL Retirement Savings Lost and Found database.
2. Search PBGC’s unclaimed retirement benefits database.
3. Review old statements, tax forms, pay stubs, and plan documents.
4. Contact the former employer, successor company, union, recordkeeper, or plan administrator.
5. Check the Department of Labor Abandoned Plan Search if the company disappeared.
6. Contact EBSA if you cannot identify the plan administrator or believe your benefits are being withheld.
7. Do not provide sensitive information to a caller or website until you confirm that it is an official government agency or the verified plan administrator.

The most important distinction is whether the plan is still operating or has ended. An ongoing plan usually requires contact with the current administrator. A terminated plan may point you to PBGC, an annuity provider, a successor company, or an abandoned-plan administrator.

Frequently Asked Questions

Q. Can an old 401(k) disappear if I change jobs?

A. The money generally does not disappear simply because you changed jobs, but the account may have been transferred, paid out, rolled over, moved to a different recordkeeper, or placed in an abandoned-plan process. Search the Department of Labor database and contact the plan administrator to determine what happened.

Q. Does finding my old employer in the DOL or PBGC database mean I will receive money?

A. No. A search result usually shows that you were associated with a retirement plan or that the plan transferred benefits for some participants. The plan administrator or PBGC must verify your identity, employment history, vesting, and whether the benefit was already paid.

Q. What if I cannot complete Login.gov identity verification?

A. Contact the former employer, union, or plan administrator directly. If you do not know how to locate them, request help from an EBSA benefits adviser. The DOL says its advisers cannot search the Lost and Found database for you, and alternative verification methods may be limited.

Q. Can I search for a deceased spouse’s lost retirement benefit in the DOL database?

A. The DOL Lost and Found database currently searches using your own verified identity and Social Security number. For a deceased spouse’s benefit, contact the spouse’s former employers, unions, or plan administrators and ask what documentation is required to establish your relationship and beneficiary rights.
