The Bay Area's Lost Money

How much unclaimed money the Bay Area is owed

Unclaimed property is money a company could not get back to you: a final paycheck, a deposit refund, an insurance payout, a bank account nobody touched for three years. By law the company has to hand it to the State Controller, who holds it indefinitely until someone claims it. Nothing about the arrangement is unusual and nothing about it is secret — there is a published process for claiming it back, free to use. It is just that almost nobody looks.

The Bay Area's share is close to what its size would predict — 20% of California's published unclaimed money for 19% of its people. The interesting variation is underneath that, between counties and between cities.

Unclaimed money by Bay Area county

Ranked by dollars per resident, which is the fairer comparison — Santa Clara has more money waiting than San Francisco simply because more people live there.¹

San Francisco leads at $462 per resident, roughly three and a half times Solano County's $130. San Mateo County is second at $282.²

What the geography suggests is that this is about density and turnover rather than wealth: unclaimed property is created whenever the link between a company and a customer breaks, and the counties at the top are the ones with the most addresses, accounts and employers per square mile. San Francisco's figure in particular is inflated by its business districts, which show up clearly in the ZIP-code table further down. Wealth is plainly part of it — but not all of it: Marin has the highest income per resident of any county in California and sits fourth on this table.

The Bay Area cities with the most unclaimed money per person

Cities of 20,000 people or more, ranked by dollars per resident.

Menlo Park tops the list at $637 a head, with Palo Alto just behind. The list does not follow a single region — it runs from the Peninsula through the South Bay to Walnut Creek — and the records themselves carry no information about why any given city ranks where it does. What we can say is what these figures are and are not: they measure money reported against addresses in a city, over many years, not the current wealth of the people living there.

Unclaimed money in San Mateo County, city by city

The county's incorporated cities and towns, ranked per resident. East Palo Alto is not in the table.³

Woodside comes out highest in the county at $820 per resident — though in a town of 5,123 people, a single $1.4M record accounts for most of the gap between it and the rest. Per-resident figures for the county's smallest places should be read with that in mind.

The Bay Area ZIP codes holding the most lost money

The top of this list is downtown and eastern San Francisco — 94105, 94109, 94111, 94104 — which are business districts as much as neighbourhoods. Unclaimed property is not only owed to individuals: a ZIP full of offices collects records addressed to businesses too, and those addresses belong to companies that have since moved, merged or closed. It is the main reason San Francisco's per-resident figure runs ahead of the rest of the region, and a reason to read the top of this particular table as a map of commercial districts rather than of household wealth.

Which companies reported the unclaimed money

The companies that turned over the most money belonging to Bay Area addresses. Names are grouped: the same company files under dozens of spellings, and we matched those back together. Court settlement funds and federal bank takeovers are kept separate rather than folded into the company they relate to.

To be clear about what this table is and is not: appearing on it is not evidence a company did anything wrong. Handing forgotten money to the state is exactly what the law requires, and a company with millions of customers will always report more than one with thousands. The list is useful because it tells you where to look, not because it assigns blame.

How much lost money Bay Area employers turned over

Filtering to companies whose main California presence is here — the technology employers, the utilities, the hospital systems, the universities — those firms collectively reported $318.8M to the state, owed to people anywhere. It is a mix: some of it is the residue of employment — a last paycheck sent to an address someone had already left, an expense reimbursement — and a great deal of it is customer money, such as balances left sitting in accounts nobody closed properly. The largest single line below, PayPal at $99.0M, is almost entirely the latter. Money left behind when someone changes jobs also turns up as forgotten retirement accounts, which are reported separately and are worth checking for on their own.

22 of 66 companies shown, ranked by total reported. Which firms count as “Bay Area” is our judgement call: we included employers whose main California presence is in the nine counties, and left out banks with a statewide branch network even where they are headquartered here, because their totals reflect branches across California rather than this region.

The typical amounts are small — a few hundred dollars in most cases, and in one case zero.⁴ What makes any of this worth chasing is that the amounts are individually forgettable and collectively large, and that they belong to people who once worked at, or held an account with, a company they have not thought about in years.

Unclaimed stock and shares nobody has collected

Cash is not the whole picture. 199,694 Bay Area records carry shares of stock — 119,404,721 shares across 9,409 different securities. California attaches no dollar value to shares, so the stock itself is worth nothing in the $1.85B above, even though the small amount of cash sitting on some of those same records is counted. The real figure is therefore higher than what we have published, not lower.

METLIFE INC dominates by a distance, on 40,821 Bay Area records with a typical holding of 17 shares. That pattern — very many records, very few shares each — is the signature of a demutualization: when a mutual insurer converts into a public company, its policyholders receive shares automatically. Many never knew, the certificates went to an address they had already left, and decades later the shares are still there. MetLife converted in 2000; Brighthouse, third on this list, was spun out of MetLife in 2017, and those shares reached the same people the same way.

DISNEY WALT COMPANY is second on the list for a different reason. It has never been a mutual company. A typical Bay Area record holds 2 shares, which is the fingerprint of shares held directly with the company's transfer agent rather than in a brokerage account — single shares bought as gifts, and small holdings built up through dividend reinvestment. Those are exactly the holdings a person is most likely to lose track of, because no broker is sending them a statement. Shares are also the fiddliest thing to recover — we have written a separate guide to claiming unclaimed stock and dividends in California.

The largest single unclaimed property records

Shown by county, with no names or ZIP codes. The underlying records are public and searchable on the state's own site; this study is about the shape of the problem, not about identifying individuals. The right-hand column is reproduced exactly as the filer wrote it, typos included — and two of these were filed under a description rather than a company name, which is its own small illustration of the problem. Records this size are very often estates, where the original owner has died; those follow a different and slower process.

7,018 Bay Area records are worth $25,000 or more. At the other end, 1,869,665 records are between $100 and $500 — which is the shape of this whole dataset: a very long tail of small amounts, and a short head of amounts that would change someone's year.

Why so much lost money is never found

The state does not hide any of this. Every record is searchable for free at claimit.ca.gov. The reason the pile keeps growing is more mundane, and it is visible in the data itself.

The addresses are often gone. Across California's published records, 980,214 owner entries have no street address at all, 1,038,200 have no city, and 1,159,365 do not even carry a state. That is money the state physically cannot return to anyone who does not come looking.

The names are typed however they were typed. Companies appear under 89,373 distinct spellings in these files — Bank of America alone accounts for 687 of them in Bay Area records. Your own name went in the same way, by whoever was doing the paperwork, possibly decades ago: with a typo, an initial, a maiden name, or your name and a spouse's run together on one line. The search matches what was typed. If it does not match what you type, you are told there is nothing. This is the single biggest reason claims fail, and it is one of several avoidable mistakes that stall California claims.

So the single most useful thing on this page: search every version of your name you have ever used, and every address you have ever lived at. Not just the current ones.

285,871 Bay Area records have more than one name on them. Those are the hardest of all — a joint account or an estate usually requires every named person, or their heirs, to be found and to sign. Whatever the record, the state wants specific proof of identity and ownership before it will pay out, and approval takes months rather than weeks.

How we did it

• Where the data comes from. The files California's State Controller publishes of the unclaimed property it holds. We keep our own copy and update it as the state republishes.
• When we pulled it. August 13, 2026, covering records California published up to August 5, 2026. This is a snapshot; the state updates regularly and these numbers will move.
• What is counted. California splits its public download into files by amount: under $10, $10 to $100, $100 to $500, and $500 and up. We analyse the two files covering records reported at $100 and above, which together hold $9.26B statewide. Records below $100 are published by the state but are not included here. The Controller's office says it safeguards more than $15.00B across over 84 million properties in total, so every figure on this page is a floor, not a ceiling.
• How we placed the money geographically. By the owner's last known mailing ZIP code as the company reported it. ZIP codes are postal delivery routes rather than areas, so there is no official ZIP-to-county table; the standard substitute is the Census Bureau's ZIP Code Tabulation Areas, and we used its 2020 relationship file to match each ZIP to a county. Where one straddles a county line it is assigned to the county holding most of its land, and where the Bay Area county holds the smaller share the ZIP is left out entirely.
• How dollars are split. When a record has several owners, its value is divided evenly between them before being assigned to a place. Without this, a jointly held account would be counted once for every name on it. We checked that adding the split values back up returns the state total exactly.
• Population figures. Census Bureau county and city population estimates for 2024, so per-resident figures are comparable across places.
• How we grouped the companies. We matched the many spellings of each company's name back to one company using a deliberately cautious set of rules. Anything we were not confident about was left ungrouped rather than guessed at, so per-company totals are, if anything, understated.
• Checking our work. Seventeen automated checks run before publication. They confirm, among other things, that splitting each record between its owners and adding it all back up returns the state total to the cent; that the county, ZIP and value-band tables all sum to the same Bay Area figure; and that the Bay Area total can be reproduced by a separately written query. Review of earlier drafts turned up several real errors — including a miscount of the East Palo Alto effect described above, and a version of these tables that counted a jointly held record once per owner. We have corrected those and stated the surviving limitations here rather than smoothing them over.

What these unclaimed money figures do not show

• Addresses are historical. The location is where a person was when a company last had good details for them, which for old records can be many years and several moves ago. A high figure for a city says as much about who used to live there as who lives there now.
• Some money cannot be placed at all. $354.5M statewide sits on records with no ZIP code, and a further $22.8M on records whose ZIP is not a valid five-digit code. None of it is in any county column, here or anywhere.
• PO boxes fall out. ZIP codes that serve only PO boxes have no Census area and so cannot be matched to a county. Records carrying a Bay Area ZIP prefix that we could not match to a county hold $116.5M — an upper bound on what this method misses in the region, since that prefix range also reaches a short way beyond the nine counties.
• ZIP codes are not city boundaries. Where the two disagree the ZIP wins, because it is the field the state actually records. The clearest casualty is East Palo Alto, noted above. San Francisco appears twice with two figures for the same reason: $462 per resident in the county table, against $451 in the city table, the difference being records whose ZIP is in San Francisco but whose reported city is written some other way.
• Small places produce unstable per-resident figures. In a town of a few thousand people, one large record moves the number a long way. The largest single record is shown alongside each San Mateo city so the effect is visible.
• Stock is counted in shares, not dollars. The state assigns no value to securities, and we have not estimated one.
• One person can hold several records. Counts of records are not counts of people. Where we refer to distinct owners, we mean distinct combinations of name and ZIP code, which will merge two people who share both.

Notes

1. 1.Every count column on this page counts records, and a record is counted once however many names are on it. Dollar columns work the other way: a record with two owners has its value split between them, so the money can be attributed to a place without being double-counted.
2. 2.The Records column adds up to slightly more than the 2,610,843 headline figure. A jointly held record whose owners live in two different counties is listed in both, so that neither county's record count understates what is there — but its value is split between them and counted once, which is why the dollar columns still sum exactly to the Bay Area total.
3. 3.East Palo Alto's main ZIP code is shared with Palo Alto, and our rule assigns a shared ZIP to whichever county holds most of its land — which puts East Palo Alto's records in Santa Clara's column rather than San Mateo's. Listing the city in this table would show a near-zero figure that is an artefact of that rule rather than a fact about the city, so it is left out. Measured across every spelling of the name, $3.5M addressed East Palo Alto is sitting in Santa Clara's total.
4. 4.A typical amount of $0.00 in that column is not an error. It means more than half of that company's records hold shares of stock rather than cash, so the middle record has no cash value attached even though it is worth something. California assigns no dollar figure to shares.

Using these unclaimed money figures

This is our second study of California's unclaimed property data. The first, a statewide breakdown of which companies hold the money, covers all 13.1 million published records rather than just the Bay Area's.
