How do I find an old 401(k)?

Start with the obvious: contact your former employer’s HR or plan administrator, and dig out any old statements to see which provider held the plan (Fidelity, Vanguard, Empower, and the like) so you can call them directly. Then widen the net with the free databases — the Department of Labor’s Retirement Savings Lost and Found, the National Registry of Unclaimed Retirement Benefits, and your state’s unclaimed-property search at MissingMoney.com.

Is there a government database for lost retirement accounts?

Yes — the Department of Labor launched the Retirement Savings Lost and Found in December 2024, created by the SECURE 2.0 Act. It’s the first government-backed search tool for forgotten workplace plans, and you access it with a verified Login.gov account. It’s still new and the data is incomplete (plan reporting has been gradual), so treat it as one stop, not the only one.

What happens to a 401(k) when you leave a job?

It usually just stays in the old employer’s plan. Smaller balances can be automatically cashed out or rolled into an IRA on your behalf, and accounts that lose contact with you can eventually be turned over to the state as unclaimed property. None of that erases your money — but it does make it easy to lose the thread.

What should I do once I find an old account?

Common options are to leave it where it is, roll it into your current employer’s plan, roll it into an IRA, or cash it out (which can mean taxes and a penalty). Each has trade-offs. Squirreld isn’t a financial advisor — confirm the details and talk to a professional about the right move for you.

How does Squirreld help?

Once you’ve tracked your accounts down, Squirreld keeps them from getting lost again: the provider, account number, and login hints live in your Vault, the portals live in Links, and a once-a-year reminder nudges you to review everything — balances, beneficiaries, and any account left behind at an old job.

How to Find a Lost 401(k) — and Stop Losing Track of Accounts

The problem

You change jobs — the 401(k) stays behind

It's one of the most common ways people lose money without spending it: you leave a job, and the retirement account quietly stays put. A new job, a move, a provider that gets bought by another — and a few years later you can't remember where it lives or who to call. It adds up. By recent estimates, there are about 29 million forgotten or left-behind 401(k) accounts in the U.S., holding roughly $1.65 trillion.

The good news: lost retirement money is almost never gone — it's just disconnected from you. Here's how to find it, and how to make sure you never have to do this search twice.

The search

Where to look for an old account

Work these in order — the first two solve most cases on their own:

Your former employer
Contact HR or the plan administrator at the company you left. If it merged or closed, note the new owner's name — you'll need it for the searches below.
Old statements and the provider
Dig up any account statement or enrollment packet to see which firm held the plan (Fidelity, Vanguard, Empower, Principal, and so on), then contact them directly with your Social Security number.
The federal Lost & Found database
The Department of Labor's new Retirement Savings Lost and Found (more below) searches for workplace plans tied to your Social Security number.
The National Registry of Unclaimed Retirement Benefits
A free lookup where employers can list former employees with unclaimed funds.
State unclaimed property
If an old account lost contact with you, the money may have been turned over to your state. Search free at MissingMoney.com (and check every state you've lived in).

The new tool

The government's Retirement Savings Lost & Found

In December 2024, the Department of Labor launched the Retirement Savings Lost and Found — the first government-backed search tool for forgotten workplace retirement plans, created by the SECURE 2.0 Act. You sign in with a verified Login.gov account, and it looks for plans associated with your Social Security number.

One honest caveat: it's new, and its data is still filling in (plan reporting has been gradual), so a blank result there doesn't mean you have nothing — it just means you should keep working the other methods above. Used together, they cover a lot of ground.

Once you find it

A quick word on what's next

When you reconnect with an old account, the usual options are to leave it where it is, roll it into your current employer's plan, roll it into an IRA, or cash it out — and cashing out can trigger taxes and a penalty. Each path has trade-offs that depend on your situation. Squirreld isn't a financial advisor; this is a nudge to go find the money, not advice on what to do with it once you have. A professional can help you choose.

Where Squirreld fits

Find it once — then never lose it again

The reason 401(k)s vanish isn't carelessness; it's that nothing keeps the thread between job changes and busy years. That's the gap Squirreld fills. It doesn't manage your money — it just makes sure you always know what you have and where.

Every account, in one list
Provider, account number, and login hints for each retirement and financial account — kept in your Vault, masked until you need them.
The portals, in Links
Each plan's login page in one spot, so checking in is a tap instead of a hunt.
A once-a-year check-up
Set a yearly reminder on a Vault entry to review it all — balances, beneficiaries, contributions, and any account left behind when you switched jobs. It's the same calm, single-email nudge behind every Squirreld reminder, just on a longer horizon.

It pairs naturally with a family emergency binder — the same accounts your future self needs to find are the ones your family would need, too.
