US Company & Group Structure Directory
Company register search for 88M+ United States companies, plus shareholder, officer and beneficial ownership records sourced directly from official government registries.
US company register data doesn't exist as a single national system — incorporation happens state by state, with beneficial ownership tracked instead through FinCEN's BOI database under the Corporate Transparency Act. It has never had a public search interface, restricted to authorised recipients like law enforcement and financial institutions with customer consent, at a 25% ownership-or-control threshold. The March 2025 Interim Final Rule exempted every domestically formed entity and every American person from reporting, cutting required filers from roughly 32.6 million to about 12,000; only foreign reporting companies doing business in a state still file. Foreign reporting companies file directly with FinCEN, though foreign counterparties have no direct access; when a domestic entity has no disclosable owner, the chain typically resolves through a foreign parent in a jurisdiction that still requires disclosure.

Analysis
What this data actually tells you about United States
Unlike most countries in this directory, the United States has no single national company register — business entities are formed and registered state-by-state, each with its own Secretary of State filing office, fees, and corporate statutes, so a company can be legally headquartered in one state while incorporated in an entirely different one. Delaware dominates this landscape disproportionately to its size: per the Delaware Division of Corporations’ 2024 Annual Report, over 2.1 million active legal entities are incorporated there, 66.7% of Fortune 500 companies are Delaware entities, and 81.4% of all 2024 U.S. IPOs chose Delaware, drawn by its specialized business-only Court of Chancery and well-developed corporate case law. Nevada and Wyoming compete for smaller LLC formations on privacy and no-income-tax grounds instead — neither state requires LLC owner names on the public filing. The closest thing to a federal business identifier is the IRS-issued Employer Identification Number (EIN), required for banking and tax purposes regardless of a company’s state of incorporation.
The federal Corporate Transparency Act’s beneficial-ownership disclosure regime has undergone a genuinely dramatic reversal since its original 2021 design: after nationwide court injunctions in late 2024 and a Treasury enforcement suspension in March 2025, FinCEN’s Interim Final Rule (March 26, 2025), made permanent by a Final Rule effective August 14, 2026, now exempts ALL U.S.-formed domestic reporting companies from beneficial-ownership reporting entirely — only foreign-formed entities registered to do business in a U.S. state must still report, and even they face no obligation to disclose U.S.-person beneficial owners. Counterparties should treat this as the current, permanent U.S. position rather than the mass-disclosure regime originally legislated in 2021. Per the SBA Office of Advocacy (2025), small businesses (fewer than 500 employees) number over 36.2 million and account for 99.9% of all U.S. businesses and almost 46% of private-sector employment — though this total includes roughly 30.4 million nonemployer sole proprietorships (Census Bureau, 2023) alongside genuine employer firms, a distinction worth keeping in mind when interpreting any single headline business count for this jurisdiction.
United States company base, broken down
Charts render from live counts. Where coverage is partial, the excluded population is stated on the chart.
Company size, by disclosed headcount
By number of employees on file. Entities with no disclosed headcount are not counted in any band.
Enterprises by size category
US Census Bureau Statistics of US Businesses (SUSB), 2022 (most recent release): of 6.4 million US employer firms, 79.2% had fewer than 10 employees, 89.4% fewer than 20, 98.2% fewer than 100, and 99.7% fewer than 500; bands above are the non-cumulative differences between these published thresholds. These are the Census Bureau’s own employer-firm size brackets, not the EU’s Micro/Small/Medium/Large standard, since the two classification systems use different employee-count thresholds and are not directly comparable. Figures cover the 6.4 million US employer firms only and exclude roughly 30.4 million nonemployer sole proprietorships tracked separately by the Census Bureau’s 2023 Nonemployer Statistics; per the SBA Office of Advocacy (2025), firms with fewer than 500 employees — the US small-business threshold, far more permissive than the EU’s — represent 99.9% of all US businesses (employer and nonemployer combined) and almost 46% of private-sector employment.

Foreign-controlled entities
No entity-count foreign-ownership percentage is published for the United States. The best available non-monetary metric is employment share: per the US Bureau of Economic Analysis ("Activities of US Affiliates of Foreign Multinational Enterprises, 2024", published July 10, 2026), 8.57 million workers were employed at majority-owned US affiliates of foreign multinationals in 2024, representing 6.1% of total US private-industry employment, concentrated most heavily in manufacturing and retail trade, with the United Kingdom, Japan, and Germany the top employment-contributing source countries. Separately, the monetary FDI position in the US reached $5.71 trillion at end-2024 (also BEA) — a stock figure, not an entity or employment share, and referenced here for context rather than as a comparable percentage.
Who uses United States ownership data
The three checks this page's data is most often run for.
KYB onboarding
Verifying a United States counterparty means confirming the beneficial owner behind the entity and evidencing where that answer came from, not just pulling the registered name.
AML and sanctions screening
Sanctions exposure often sits above the operating company, in a holding layer registered elsewhere. Screening the local entity alone will not surface it; screening the resolved ownership chain will.
Supplier and credit risk
Only 6,450 United States entities have digitized accounts on file, so group membership is often a better solvency signal than a standalone balance sheet.
