Switzerland Company Check (UID) — KYB & due diligence MCP

Switzerland Company Check (UID)

Check companies in Switzerland by their UID (enterprise identification 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.

• 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 one Switzerland company or a thousand — 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.

What we check

Source	Licence	Publisher updates
Zefix — Central Business Name Index of the Federal Commercial Registry Office (FCRO / EHRA), LINDAS linked data (ld.admin.ch) (CH)	Several, see Data licences	weekly
GLEIF Global LEI Index: Level 1 (LEI-CDF), Level 2 (RR-CDF), Reporting Exceptions	CC0 1.0	daily
Official sanctions lists: US OFAC (SDN and Consolidated non-SDN), EU consolidated financial sanctions (FSF), UK Sanctions List (FCDO) — legal entities only	Several, see Data licences	daily

Data refreshed at least weekly; 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.

Switzerland: The open Zefix dataset (LINDAS) lists only legal entities currently entered in the Swiss commercial register (including those in liquidation); entities already deleted are not in it, so a valid UID with no record is reported as unknown and not charged. Sole proprietorships, general and limited partnerships are not supported. Registration dates are not published in the dataset. A valid UID without a record therefore returns not_found: null (unknown, not fictitious) and is not charged.

Not affiliated with or endorsed by the Federal Commercial Registry Office (FCRO / EHRA) or the Federal Office of Justice. Data from Zefix, the Central Business Name Index, published as linked open data on LINDAS (updated daily by the FCRO). The open dataset contains only entities currently in the commercial register: a deleted entity is not in it, so a valid UID with no record is returned as unknown (flags.not_found = null) and not charged. Status: a name carrying the statutory suffix "in Liquidation" / "en liquidation" / "in liquidazione" → in_liquidation and flags.liquidation = true; a name carrying a bankruptcy or composition-liquidation suffix ("in Konkurs", "en faillite", "in Nachlassliquidation" …) → insolvency and flags.insolvency = true; otherwise active. Zefix itself does not record insolvency, and a liquidation after bankruptcy often carries only "in Liquidation", so without such a suffix flags.insolvency is null (unknown), never false. Registration dates are not published in the dataset. Sole proprietorships and general / limited partnerships (whose unlimited partners are natural persons) are not supported; Swiss and foreign branches are returned only when their name shows a legal-entity form. Addresses are city-level only.

Identifiers

Country	Identifier	Format	Example
Switzerland (CH)	UID (enterprise identification number)	CHE-123.456.789 (CHE + 9 digits with a mod-11 check digit); the CHE prefix, dots, dashes and a VAT/register suffix (MWST, TVA, IVA, HR, RC) are optional	CHE-105.832.037

Spaces, dashes and a country prefix are accepted. Legal entities only: sole traders and other natural persons are not supported, not stored and not charged. No data about people (officers, owners, contacts) is ever returned; addresses are city level only.
