US Company Verification (KYB) & New LLC Filings by State

Check whether a US company exists and is in good standing, straight from the official business registers that New York, Colorado, Connecticut, Oregon, Texas and Pennsylvania publish as open data. Paste a list of names, as they appear on an invoice or a contract, and get one verdict per name: the registered name, standing (active, delinquent, inactive), the status exactly as the state publishes it, formation date, entity type, registry id, address and registered agent where published. A name that is not found costs nothing.

The second mode lists the companies formed between two dates in those six states, about 23,000 a week, with address, registered agent (Colorado, Oregon, New York), email (Connecticut, 100 % of new filings) and organizers (Pennsylvania). Schedule it for a feed of new LLCs and corporations.

Verify companies (KYB)

{
  "mode": "verify",
  "companies": ["Starbucks Corporation", "Tesla, Inc.", "Acme Holdings LLC | CO, TX"]
}

Each name is searched in every state you choose (or the six). Spelling of punctuation and legal form does not matter: "Tesla, Inc." finds "TESLA INC". The search also catches names the register writes differently, such as TOYS "R" US, INC. for "Toys R Us, Inc.".

matchType	Meaning
exact	Same name, ignoring punctuation and case. When a state has an exact match, only exact matches are returned for that state.
same_name_other_form	Same name with another legal form ("Starbucks Corp" for "Starbucks Corporation"); up to 3 per state, active first.
starts_with	Only with Also return names that start with yours.

Rows with recordType: "not_found" say which registers were searched and are not charged.

Measured on 2026-10-15: "Starbucks Corporation" is found exact in Colorado (Good Standing), Connecticut (Active), Oregon, Texas (right to transact business: A) and Pennsylvania; "Tesla, Inc." in Colorado, Connecticut, New York, Oregon and Texas. Four names checked against six states in about one minute.

What each register contains

State	Register	Contains	Standing
Colorado	Secretary of State, Business Entities (3.1 M)	every company, active and dissolved	Good Standing / Exists = active; Delinquent, Noncompliant = delinquent; dissolved, withdrawn, revoked, merged = inactive
Connecticut	Secretary of the State, Business Registry (1.3 M)	every company, active and dissolved (name reservations excluded)	Active = active; Forfeited, Dissolved, Revoked, Withdrawn... = inactive
New York	Department of State, Active Corporations (4.3 M) + full filing history	active list; with Check New York's full history, also inactive and suspended companies	last status in the state's status history
Oregon	Secretary of State, Active Businesses (1.6 M rows)	active companies only	active
Texas	Comptroller, Active Franchise Taxpayers (3.5 M)	companies set up for franchise tax	right to transact business code A = active; other codes delivered as published
Pennsylvania	Department of State, Registered Businesses (4.2 M rows)	current registrations only	registered

In Oregon, Texas and Pennsylvania "not found" means "not in the active or current list", not "never existed"; the note of the not-found row says so.

New company filings

What the registers do not publish, so this Actor does not promise

• Phone numbers. None of the six registers has them.
• Email outside Connecticut.
• Owners or members. Pennsylvania lists organizers and officers; the others do not list owners.
• Texas entity types in words. Texas publishes a code (CL, CF, CI...) explained in a separate document; it is delivered as entityTypeCode, not translated.
• Hawaii, Delaware, California, Florida and the other states: their registers are not open data or sit behind a CAPTCHA. Hawaii's open file was tested and left out: its dates are broken text ("Oct 3, 0217") and it misses large companies.
