Part of State entity directories: reaching the real filing office
State entity directories facts: signal versus noise
State entity registers: the facts that hold in every jurisdiction, the eight dimensions along which the rest varies, and the question that settles each one.
The guides to state entity directories all start the same way: everything varies by state. True, and useless.
What helps is the reverse list. A few rules hold everywhere. The rest differ along specific dimensions. Knowing which is which lets you work in an unfamiliar state without assuming too much or checking everything from scratch.
What to take away
- A handful of things are true of every register, and they are the ones worth internalising.
- The variation is not infinite. It runs along about eight named dimensions, and each has a question that settles it.
- Anything expressed as a fee, a deadline, or a requirement belongs to the office and to the day you read it, never to a page like this one.
What holds everywhere
Registration is a state function. There is no federal register of ordinary companies and no national entity number, which the IRS guidance on starting a business reflects by pointing readers at their own state. A company doing business in five states has five registrations and five unrelated identifiers: an LLC formed through the Delaware Division of Corporations carries a Delaware file number, and the same company registered in Texas carries one issued by the Texas Secretary of State. California's Secretary of State, New York's Department of State, Florida's Division of Corporations, and the Wyoming Secretary of State each keep a register of their own, and none of them reads another's.
The office is ministerial. It checks that a form is complete and the fee is paid. It does not verify that the contents are true. The signature that attests to the truth is the filer's, and everything on a record except the office's own actions was asserted by a filer.
Formation creates a legal person, not a business. The filing — articles of incorporation in some states, a certificate of formation in others — brings into existence the separate entity that the Legal Information Institute describes under corporation, and nothing about trading, staff, or revenue follows from it.
An identifier is issued and is stable within that register. It survives name changes, address changes, and usually reinstatement, and it means nothing on any other register, which is the whole argument of entity number lookup.
The record is a set of dated statements. Every field was true, as far as a filer was concerned, on the date of the document it came from. There is no field on the page that means "as of today" except the office's own status action.
Something separate holds the things people most want. Litigation sits with the courts, federal tax standing with the IRS, state tax standing with the state revenue department, liens with the county recorder, licenses with the issuing board, and trade names with the county clerk in many states. None of it is on the entity register, everywhere, without exception.
The register exists so the entity can be found and served, not so people can be looked up. Which details get collected is a choice each state made: the Delaware Division of Corporations and the Wyoming Secretary of State do not require an LLC's members to be named in the formation document, while other states collect them in an annual filing. The withholding is design rather than concealment.
The dimensions along which it varies
Eight, and each has one question that settles it for a given jurisdiction.
Eight questions for any register
- Which office holds the register?
- What are the office's status terms?
- Which roles does the report collect?
- How often is a report due?
- Where does the assumed-name index sit?
- Are filings viewable, sold, or index-only?
- Is search exact, starts-with, or contains?
- Which entity types does the jurisdiction offer?
| Dimension | The question to ask the office |
|---|---|
| Which office holds the register | What is this jurisdiction's business filing office actually called, and is its register split across divisions? |
| Status vocabulary | What are the office's own status terms, and where is the legend? |
| Officer disclosure | Which roles does the periodic report collect, for which entity types? |
| Report cadence | How often is a periodic report due for this entity type? |
| Trade names | Does the assumed-name index sit with this office or with a county? |
| Document images | Are filings viewable, sold, or index-only, and how far back? |
| Search behavior | Is matching exact, starts-with, or contains, and are filters applied by default? |
| Entity types available | Which forms of entity does this jurisdiction offer, and under what names? |
Entity types are not a fixed national menu. The vocabulary a US office actually uses is short — LLC, corporation, limited partnership, limited liability partnership, nonprofit corporation — but which of them a state offers, and what it calls each one, differs from register to register.
The federal tax treatment of a form is separate from state formation, which the IRS overview of business structures keeps distinct.
Two practical questions sit outside those eight, and both are answered on the office's own page. First, coverage: some registers return only entities in good standing unless you ask for the rest, so a dissolved company that should appear simply does not. Second, what you get back: a parsed data record, or the image of the filing itself. Delaware's Division of Corporations returns the entity's core fields and its filing history, and copies of the filed documents are ordered from the office rather than downloaded from the result.
What no page should tell you
Fees. Deadlines. Penalties. Form numbers. Processing times. Whether a particular filing is required for a particular business.
All of these are set by an office and changed by that office, sometimes annually. Anything you read about them anywhere, including here, is a statement about a moment somebody else was living in. Every filing office publishes its own fee schedule, forms list, and processing notes; that page is the only source worth quoting, and quoting it means going there rather than remembering.
This is not caution for its own sake. A wrong fee wastes an afternoon; a wrong deadline can lose a registration, and losing one shows up as a change in registration status that a counterparty will eventually see when they run their own company verification.
Where the variation bites hardest
Officer disclosure, because an empty field is read as concealment by anyone who has not asked whether the state collects the field at all. New York's Department of State record lists a chief executive officer and a principal executive office; Delaware's Division of Corporations publishes the registered agent, the file number, the status, and the filing history, and no officers at all. That misreading is the subject of officer lookup.
Trade names, because a search of the entity index for a name that was only ever registered as an assumed name returns nothing, and nothing looks like an answer. Florida handles fictitious names inside the same Division of Corporations register, searchable on Sunbiz beside the entity records; California sends a fictitious business name statement to the county clerk, so no single statewide search covers the state.
Search behavior, because a starts-with index quietly hides every company whose distinctive word is not first, and the page does not say so. Type "Holdings" into a register that indexes from the first word of the name and you get nothing; type it into one that matches anywhere in the name and you get the company. The office's help text usually states which rule it uses, and it is worth five minutes before you conclude that a company is not registered.
Status vocabulary, because two offices use the same word for different states of the world, and a checker who learned one jurisdiction's meanings will carry them into the next. Florida's Sunbiz shows a plain Active or Inactive; another register looking at the same company may say Dissolved, Revoked, Forfeited, or Suspended, and the word it chooses changes what the record appears to say about the business.
The working habit
Before drawing anything from an unfamiliar register, spend five minutes on the office's own help or scope page and answer the eight questions above for that jurisdiction: what the filing office is called, which entity types it offers, how its name search matches, what its status words mean, and whether it keeps trade names at all. Write the answers down beside the office's address. Every later search on that register is then interpretable, and the note is reusable by everyone else who has to work there.
Five minutes before searching
- Open the office's own help or scope page
- Answer the eight questions for that jurisdiction
- Write the answers beside the office's address
- Interpret every later search on that register
- Reuse the note for everyone else working there
The alternative, which is to carry assumptions from the last state you used, is the single most productive source of confident wrong findings in this whole field, and the state entity directories pillar exists largely to head it off.
Common questions
Is there really no national register at all?
None for ordinary companies. Federal systems exist for specific purposes — securities filings on EDGAR, registrations in SAM.gov for federal contracting — and each covers only the entities that participate in that purpose. Neither is a register of American businesses.
If everything varies, how do people work across many states?
By keeping a short note per office answering the eight questions, and by never assuming a behavior observed in one place applies in another. The notes are small and they last.
Which dimension should I check first in a new jurisdiction?
Search behavior, because it determines whether you can find anything at all, and a nil result caused by matching is indistinguishable from a nil result caused by absence.
The office's help page contradicts something I read elsewhere. Who wins?
The office, always, on anything about its own register. Everything else is a copy of what the office said at some point in the past.
