US States Company Check — KYB in 5 US states

US States Company Check

Check any Connecticut, Colorado, Pennsylvania, Iowa and District of Columbia legal entity by its US-CT Connecticut Business ID (Secretary of the State), US-CO Colorado Secretary of State entity ID, US-PA Pennsylvania Department of State entity (filing) number, US-IA Iowa Secretary of State business number and US-DC DC DLCP file number in one call and get a clean English JSON answer with red flags, source attribution and a date on every field. Built for AI agents (MCP) and for KYB / AML onboarding, counterparty and supplier due diligence, vendor risk and compliance checks.

Same data as our single-country Actors. This Actor puts Connecticut Company Check, Colorado Company Check, Pennsylvania Company Check, Iowa Company Check and District of Columbia Company Check behind one MCP server: the same registers and the same answers, refreshed at least weekly. If you need only one of them, its own Actor does the same.

• One number → one answer from official open registers plus GLEIF Global LEI Index: Level 1 (LEI-CDF), Level 2 (RR-CDF), Reporting Exceptions and Official sanctions lists: US OFAC (SDN and Consolidated non-SDN), EU consolidated financial sanctions (FSF), UK Sanctions List (FCDO) — legal entities only.
• One schema for every country: the same fields and flags whether you check Connecticut or Colorado or Pennsylvania or Iowa or District of Columbia — your agent parses one format.
• Agent-ready: an MCP server (Streamable HTTP, /mcp) with check_company, check_companies and list_sources, a plain GET /check?country=&id= endpoint, and classic batch runs (list of numbers → dataset).
• Change history: registers publish only the current state; we keep our own snapshots, so every answer shows what was added or removed since history_since (e.g. a status change or a new sanctions listing).
• Pay per check (one charge per company answered; the price is on the Pricing tab), no subscription. Malformed numbers, sole traders and individuals are not charged. In Standby (MCP / HTTP) mode Apify also bills the small platform usage of the server run, as for every Standby Actor. Set a maximum cost per run in Apify to cap spending: when it is reached, the Actor returns an error instead of data.

Data refreshed at least weekly (from the latest published files: the Pennsylvania and Iowa register is published monthly, so its data can be up to a month old); every field carries its source date (provenance), and every answer lists each source with the date it was loaded (sources[].loaded_at; list_sources is free).

flags — true is a red flag: not_found (the number is not in the register dump), not_active, insolvency, liquidation, sanctions (match by registration number or LEI), sanctions_name_match (same name, same country: verify manually). false means there is no record in the loaded snapshot — it is not a clean bill of health. null means unknown. Call list_sources (free) for load times.

Connecticut: Entities on the Connecticut Secretary of the State business registry: domestic and foreign-registered corporations, LLCs, limited partnerships, LLPs, statutory trusts and other registered entities, active and closed (dissolved, forfeited, revoked, withdrawn, merged). Business IDs have no check digit, so an ID without a record is reported as unknown and not billed. Not included: trade names (filed with town clerks), sole proprietors, general partnerships (including LLPs that renounced LLP status), name reservations, foreign name registrations and rejected filings. A valid Connecticut Business ID without a record therefore returns not_found: null (unknown, not fictitious) and is not charged.

Colorado: Business entities on file with the Colorado Secretary of State (domestic and foreign LLCs, corporations, nonprofits, partnerships, cooperatives), including dissolved, withdrawn and merged ones since 1864. The entity ID has no check digit, so an ID with no record is reported as unknown and not charged. Trade names (DBAs) and sole proprietorships are not supported. A valid Colorado Secretary of State entity ID without a record therefore returns not_found: null (unknown, not fictitious) and is not charged.

Pennsylvania: Business registrations currently active with the Pennsylvania Department of State (domestic and foreign business and nonprofit corporations, LLCs, limited partnerships, LLPs, business trusts, authorities, land banks, credit unions). Dissolved, cancelled, withdrawn and merged entities are not in the open dataset, so an entity number with no record is reported as unknown and not charged. Fictitious names (DBAs) and sole proprietorships are not in the dataset. Formation dates are not published. A valid Pennsylvania Department of State entity without a record therefore returns not_found: null (unknown, not fictitious) and is not charged.

Iowa: Business entities currently active with the Iowa Secretary of State (domestic and foreign corporations, nonprofits, LLCs, limited partnerships, LLPs, cooperatives, banks, insurers, authorities); sole proprietorships and DBAs are not registered with the Secretary of State. Dissolved, withdrawn and merged entities are not in the open dataset. A valid Iowa Secretary of State business number without a record therefore returns not_found: null (unknown, not fictitious) and is not charged.

Iowa: The Iowa open dataset has no insolvency, liquidation or dissolution data: for Iowa flags.insolvency and flags.liquidation are always null (unknown), never false.

District of Columbia: Business entities on file with the DC Department of Licensing and Consumer Protection (domestic and foreign corporations, nonprofits, LLCs, limited and limited liability partnerships, cooperatives, statutory trusts), including revoked, dissolved, withdrawn and merged ones. File numbers have no check digit, so a number with no record is reported as unknown and not charged. Trade names and sole proprietorships are not in the register. A valid DC DLCP file number without a record therefore returns not_found: null (unknown, not fictitious) and is not charged.

District of Columbia: Not affiliated with or endorsed by the Government of the District of Columbia or DLCP. Contains data from the DLCP Corporate Registration dataset, Open Data DC (https://opendata.dc.gov), licensed under CC BY 4.0; modified (selected fields only, statuses mapped, personal data masked in names). Status: "Active - In Good Standing" → active; "Active - Not in Good Standing" → inactive (flag not_in_good_standing); "Revoked" means administrative dissolution for a DC entity (dissolved, flag liquidation; it may be reinstated) and revocation of the registration for a foreign entity (inactive, the entity itself may still exist in its home jurisdiction); "Inactive - Cancelled" → dissolved for DC entities and inactive for foreign registrations; Withdrawn, Converted and Domesticated → inactive; Terminated → dissolved for DC entities and inactive for foreign registrations; Dissolved, Merged and Consolidated → dissolved. flags.registration_revoked is true when the register status is "Revoked" (a DC entity administratively dissolved, or a foreign entity whose DC registration was terminated), false for any other known status, and null when the status is unknown or conflicting. flags.insolvency is always null: the register does not record bankruptcy. Registered agents and street addresses are not returned.
