Part of Secretary of state search: how to run one from cold
Secretary of state search: which index answers which question
Secretary of state search indexes explained: which register answers which question, why trading names defeat an entity search, and how to record a nil result.
"Searching the secretary of state" sounds like one action. It is not. A state filing office is a custodian of several separate indexes, each holding a different kind of document and answering a different question. Searching the wrong one is the most common reason a lookup comes back empty for a business that plainly exists.
This page is a directory of the indexes: what each holds, what a hit in it proves, and which questions it cannot touch.
What to take away
- The bottom three rows are where most misplaced confidence comes from.
- Start with the legal name and state if you have them; if not, start with what you have and expect to iterate.
- Note the office you used and the exact address you reached it at, the indexes you searched, the queries you ran, and the date.
The indexes a state filing office commonly holds
Which of these sits with the state filing office rather than another agency or a county varies by jurisdiction. Treat the list as the set of things to look for, not as a description of any particular state.
Three indexes, three answers
Entity register
- What it holds
- Formed entities
- Who files
- Corporations, LLCs
- Where kept
- State office
- What a hit proves
- On register today
Assumed names
- What it holds
- Trade names
- Who files
- DBAs, fictitious names
- Where kept
- State or county
- What a hit proves
- Name registered
Financing statements
- What it holds
- Secured claims
- Who files
- Lenders, suppliers
- Where kept
- Same office, separate
- What a hit proves
- Claim filed
The entity register. Corporations, LLCs, partnerships, and nonprofits formed in the state, plus out-of-state entities registered to do business there. Formation documents, amendments, periodic reports, status, and the entity identifier. This is what people mean by "the business search", and it is the right index for the questions in a company verification routine.
Assumed names. Trade names, DBAs, and fictitious names: the register of businesses operating under a name that is not their legal one, a category the Legal Information Institute defines under fictitious business name. In some states this sits with the filing office; in others with a county clerk; in others it is not required for certain entity types at all. It is the most commonly missed index, and the next section explains why.
Financing statements. Filings recording that a lender or supplier has claimed a security interest in a business's assets. Often maintained by the same office, always searched separately. A hit tells you somebody has a claim on collateral; it does not tell you the amount outstanding, and a stale filing may sit there long after the debt is repaid.
State trademark and service mark registrations. Separate from federal registration and much narrower in effect; the USPTO's own note on what a trademark protects is the quickest way to see where the two systems sit relative to each other. Relevant if you are checking a name for use, largely irrelevant to verifying a counterparty.
Notaries, apostilles, and authentications. Present at most offices, rarely part of a verification exercise, occasionally the reason someone is on the site in the first place.
Some form of certificate service. Where you order a certificate of good standing or existence, and copies of filed documents.
Where the indexes actually sit: three states
- Delaware.The entity register and the state's UCC financing statements both sit with the Division of Corporations, and a search there returns an entity file number you can carry into later lookups.
- California.The entity register and state trademark registrations sit with the Secretary of State's business search, branded bizfile Online; fictitious business name statements are filed with the county clerk; professional licensing sits with the boards under the Department of Consumer Affairs; tax questions go to the Franchise Tax Board.
- New York.The entity register is the Department of State's Corporation and Business Entity Database, and UCC financing statements are filed with the same department; litigation records stay with the courts.
Each office prints the same idea in its own field — Delaware's file number, California's entity number, New York's DOS ID — and the search box generally takes either a name or that number, with the number the more reliable of the two.
Fees are not part of any register. Certificates of good standing or existence, document copies, and apostilles are priced per document on each office's published fee schedule, so check the office's fee page before you order.
The gap that makes searches fail: trading names
Three different strings can refer to the same business, and only one of them is in the entity register:
- The legal name, filed with the state, appearing on the formation document.
- The trading name, on the sign, the website, and the invoice.
- The assumed name registration, if one exists, which is the record connecting the two.
An entity-name search finds only the first. So a business trading as something else is invisible to it, no matter how carefully you spell the query. This is why perfectly real companies "don't exist" in a search, and why the fix is almost never a better search of the same index.
What to do about it, in order:
- Search the assumed-name indexthe state filing office if it keeps one, otherwise the county clerk for the county where the business operates — for the trading name exactly as it appears on the sign, the invoice, or the website.
- Take the legal name from that registration, and note the entity number if the record shows one.
- Search the entity register for that legal name in the state the registration names.
- If no assumed-name registration exists, search the entity register for name variants, and widen to the state of formation rather than the state of operation.
- If the two names still will not connect, ask the counterparty for its legal name, state of formation, and entity number, and compare those against the register.
Resolving a trading name
- Ask for legal name and state
- Search assumed-name index
- Search register on root word
- Check foreign entity registration
- Confirm which entity is counterparty
The absence of an assumed-name registration is worth noting rather than alarming. Requirements differ, and plenty of businesses trade under an unregistered brand without any intent to obscure anything.
Matching questions to indexes
| Your question | Index to search | What a hit proves |
|---|---|---|
| Does this legal entity exist here? | Entity register | It is on this register, under this name, today |
| Who is behind this shopfront name? | Assumed names | A named entity registered this trading name |
| Is this entity current on its filings? | Entity register, status field | Compliance with this office only |
| What has this entity filed over time? | Entity register, filing history | Which documents the office accepted, and when |
| Has anyone claimed its assets as collateral? | Financing statements | A claim was filed; not its current balance |
| Where do legal papers go? | Entity register, agent record | A service address, not a place of business |
| Is it licensed for regulated work? | Not here: a licensing board | Nothing; wrong agency |
| Does it owe tax? | Not here: the revenue agency | Nothing; wrong agency |
| Has it been sued? | Not here: court records | Nothing; wrong agency |
The bottom three rows are where most misplaced confidence comes from. A clean result in the entity register gets read as a clean result generally, when the office holds no information about any of those subjects.
The three rows the entity register cannot answer point somewhere else, and none of them is the filing office. Licensing: the state's professional licensing boards, such as the boards under California's Department of Consumer Affairs or the Texas Department of Licensing and Regulation. Tax: the state revenue department — California's Franchise Tax Board, New York's Department of Taxation and Finance — and the Internal Revenue Service for federal liens. Litigation: the courts' own records, PACER for federal cases and the state trial court's case search for state cases. A clean entity register hit in California therefore says nothing about a contractor's license, a Franchise Tax Board balance, or a suit in the county superior court.

A search routine that fails informatively
- Start with the legal name and state if you have them; if not, start with what you have and expect to iterate.
- Search the entity register broadly (root word, no suffix), and narrow the result list rather than perfecting the query.
- If nothing returns, try name variantspunctuation, ampersand versus "and", articles, common misspellings.
- Then try the assumed-name index, and check whether that index is with the state or a county.
- Then consider other states, since the business may be registered where it was formed rather than where it operates.
- Only then record a negative, and record it preciselywhich indexes, which spellings, which date.
"Not found" is evidence only when it names what was searched. Without that, it is just a shrug in a file.

- Record the negative precisely
Before you conclude
Note the office you used and the exact address you reached it at, the indexes you searched, the queries you ran, and the date. Capture the entity identifier the moment you have a match and use it for every subsequent lookup, because it is the only field that will still be reliable when the name changes.
Record before you conclude
- Office used and exact address
- Indexes searched
- Queries run
- Date of search
- Entity identifier once matched
The broader question of getting to the right office — Delaware's Division of Corporations, California's Secretary of State business search, New York's Department of State — and of telling those offices apart from the commercial sites that sell copies of their records, is covered in the secretary of state search overview and in state entity directories.
Common questions
How do I know which index the search box is actually querying?
Read the office's search help page once for that state. Several offices run more than one index behind a single field and pick for you, and a nil result means nothing until you know which one answered.
The assumed-name index is at a county. Which county?
Usually the one where the business operates, and sometimes more than one. Ask the office or the counterparty rather than guessing, because searching the wrong county produces the same empty result as searching nothing.
A financing statement is on file. Should I walk away?
No. Secured lending is ordinary, the filing shows a claim rather than a balance, and stale filings sit there long after debts are repaid. It is a question for the counterparty, not a finding.
I found the trading name but it points at a different company. Now what?
Stop and establish which legal entity is on your contract before anything else. This is the single most valuable thing this whole exercise produces, and it is worth a direct conversation rather than more searching.
Do I need to search every index every time?
No. For most checks the entity register and its status are the whole job. The rest of the list earns its time when the exposure is large or when the entity register has come back empty.
