LLC Lookup: Business Entity Search in Six States, the IRS and the SEC

Type the business name you want. The check asks the registries of New York, Colorado, Oregon, Connecticut, Texas and Florida at the same time — plus the IRS list of tax-exempt organizations and SEC filers — and shows each one as it answers, with a verdict under that state’s own name rule, the statute it comes from and the official search to confirm it.

Not legal advice — and not a name approval

A name that shows no match in these datasets is not guaranteed to be accepted by the Secretary of State: each state applies its own distinguishability rule when you file, the public datasets leave out some records (reservations, recent filings, inactive entities in some states), and a name can be refused for other reasons such as restricted words. Confirm with the official search before you file, and talk to a lawyer about trademark conflicts.

LLC name availability: how each state decides, and what the check reads

Every state requires a new LLC’s name to be “distinguishable” from the names already on its records — but each state decides differently what counts as a difference and which records count. The verdicts above follow these rules, read from the statute or the Secretary of State’s own guidance on 2026-10-02.

State	Registry data	What to keep in mind	Not a difference	Rule
New York	4,291,309 records · updated monthly	Active entities only, as of the last month-end; reservations and foreign entities’ fictitious names are not in the data.	Not listed in the statute	N.Y. Limited Liability Company Law §204
Colorado	3,117,458 records · updated daily	Colorado counts the designator and spacing; “Delinquent” or “Dissolved” added to a name frees the original.	Periods, commas, underscores and apostrophes; Upper- versus lowercase letters	Colorado Secretary of State, Entity names FAQ (citing C.R.S. §7-90-601)
Oregon	566,852 records · updated weekly	Active registrations only; assumed business names count under ORS 63.094(4).	Not listed in the statute	ORS 63.094(4) (2025 edition)
Connecticut	1,300,742 records · updated daily	Every status is in the data; Active and Reserved hold the name, dissolved and forfeited do not.	Words or abbreviations that indicate the type of entity — “corporation”, “Inc.”, “Limited”, “Ltd.”, “L.L.P.” and the like	Conn. Gen. Stat. §34-243k(b), (d)
Texas	3,473,267 records · last refreshed Sep 26, 2026	Comptroller franchise taxpayers, not the SOS index: reservations and non-taxpayers are missing.	Upper- or lowercase letters and typeface; Punctuation, accent marks, periods, spaces or symbols; Articles or conjunctions; Repeated or missing letters that do not change the name	Tex. Bus. Orgs. Code §5.053
Florida	12,976,217 records · quarterly file + daily updates	Index built from the Division’s data files (through 2026-10-01); inactive names can stay unavailable for 120 days to 1 year.	A suffix; A definite or indefinite article; The word “and” and the symbol “&”; The singular, plural, or possessive form of a word; A punctuation mark or a symbol	Fla. Stat. §605.0112(1)(b) (LLCs)

The verdicts are Same name on record (an active entity, reservation or — in Oregon — assumed business name already uses it, compared the way the state compares names; in New York, Oregon and Connecticut, whose statutes do not list every difference that counts, under a cautious reading), Recently dissolved (Florida only: a dissolved name stays unavailable for 120 days, or a year after an administrative dissolution), Used before (inactive), Similar names on record and No match in this dataset. None of them means “available”.

Quick answers

How do I check if an LLC name is available?

Search the name in the Secretary of State’s records for the state where you will file, then compare it with that state’s distinguishability rule. This page runs the first step in six state registries at once and applies each state’s rule as a heuristic. Only the Secretary of State decides when you file, so confirm with the official search linked on each result before you order anything with the name on it.

Does “no match” mean the name is available?

No. It means none of the records in that registry’s public data contain those words. Each dataset has gaps — New York and Oregon publish active entities only, Texas publishes the Comptroller’s franchise taxpayers rather than the Secretary of State’s name index, and none of the datasets includes every name reservation. A name can also be rejected for other reasons, such as restricted words.

Do LLC, Inc. or punctuation make a name different?

In most of these states, no. Florida’s statute says a suffix, an article, “and” or “&”, singular or plural, and punctuation do not make a name distinguishable; Texas rules treat case, punctuation, spaces, articles and conjunctions the same way; Connecticut ignores the entity designator. Colorado is the exception: its Secretary of State says a different designator, spacing or an article does make a name different.

Can I look up any company’s EIN here?

Only where the EIN is public. The IRS publishes the EIN of every organization it recognizes as tax-exempt, and companies that file with the SEC often include theirs in the filing — both appear in the results. A private company’s EIN is not a public record, so no free lookup can show it.

Which states does this cover?

New York, Colorado, Oregon, Connecticut and Texas through the data each state publishes on its open data portal, and Florida through an index built from the Division of Corporations’ own data files. For any other state, use the Secretary of State’s own search; a state is added here only when its registry data can be checked the same way, with its name rule cited.

Is what I search saved?

SealForms does not log or keep what you search. To answer, the SealForms server sends the name to the state open-data portals and to the SEC, which apply their own policies; Florida and IRS records are looked up in the SealForms index. Identical searches are cached for up to 24 hours under a one-way hash of the name so the state portals are not asked twice.

IRS: Exempt Organizations Business Master File Extract — 1,964,958 organizations, posted 2026-09-08. Nonprofits the IRS recognizes as tax-exempt, in every state. Their EIN is public — the IRS publishes it.
SEC: EDGAR’s company index and filer records, requested under the SEC’s fair-access policy (declared user agent; requests are batched, rate-limited and cached to stay within the SEC’s fair-access limit). Public companies, funds and private companies that filed an SEC form such as Form D. The EIN and state of incorporation appear when the filing includes them. Most small LLCs never file with the SEC.

Privacy. The check sends only the name you type. It never shows registered agents, officers, home addresses or the e-mail column Connecticut publishes, and SealForms does not keep the searches; the state portals and the SEC receive the name and apply their own policies. Results are cached for up to 24 hours under a one-way hash of the name, so a repeated search does not hit the state portals again. There are no pages about individual companies or people on this site.
