Data Sources

Switzerland uses two official federal-level sources. For a given entity, all company data comes from a single primary source (Zefix), with legal representative data extracted separately from SOGC publications.

All company types

Zefix (Zentraler Firmenindex): The Central Business Name Index, operated by the Federal Office of Justice (FOJ) since 2004. Zefix aggregates data from all 26 cantonal commercial registers into a single searchable index via a REST API. This is the primary source for all company data: legal name, status, legal form, registered address, share capital, activity description (purpose), and identifiers. Zefix data is sourced from the cantonal commercial registers, which are the authoritative registers of record.
SOGC/SHAB (Swiss Official Gazette of Commerce): The Schweizerisches Handelsamtsblatt / Feuille officielle suisse du commerce, published electronically since 2002 and managed by SECO. All commercial register mutations are published in the SOGC as structured text. Used for two purposes: (1) as the source for legal representative extraction via AI parsing of publication texts (Zefix does not provide structured legal representative data); (2) as the source for the Certificate of Incorporation document (the SOGC publication announcing the initial registration).

Cantonal Commercial Registers (for documents)

Switzerland has 26 cantonal commercial registers (Handelsregisterämter), each maintaining the register of companies domiciled in that canton. While Zefix serves as the central index for company data, the cantonal registers issue the Trade Register Extract documents. There are two technical implementations:

chregister.ch: A web application used by 22 cantons (AG, AI, AR, BE, BL, BS, GL, GR, JU, LU, NW, OW, SG, SH, SO, SZ, TG, TI, UR, VS, ZG, ZH). Trade register extract PDFs are retrieved automatically.
HRC Modern: An Angular application with a REST API used by 4 cantons (Fribourg, Geneva, Neuchatel, Vaud). Trade register extract PDFs are downloaded directly via HTTP.

The cantonal commercial registers are the authoritative source of record. Zefix aggregates their data into a searchable central index but does not itself issue official documents. Trade register extracts are issued by the relevant cantonal register.

Company Identifiers

Query Identifiers

Company Type	Source	Format	Example	Notes
All registered entities	Zefix	CHE + 9 digits (UID)	`CHE408600128`	For company profile, use without separators

UID Format Breakdown: CHE-408.600.128 = CHE (country prefix, always CHE for Switzerland) + 9 random non-descriptive digits. The UID (Unternehmens-Identifikationsnummer) is assigned by the Federal Statistical Office and is permanent.

UID Format for Profile vs SearchFor the companyProfile endpoint, only the UID format without separators is accepted: CHE408600128. For search, both CHE-408.600.128 (with separators) and CHE408600128 (without) are supported. The system automatically normalizes the format internally.

Identifiers in API Response

Once you retrieve company data, the identifiers object contains all available identifiers for that entity:

Identifier Type	Format	Example	Notes
`uid`	CHE + 9 digits	`CHE-408.600.128`	UID (Unternehmens-Identifikationsnummer), always present
`ehraid`	Numeric	`12345678`	EHRA ID (Federal Commercial Registry Office internal ID), when available
`chid`	CH + digits	`CH12345678901`	CH-ID (legacy 13-digit identifier, no longer used publicly), when available

Search Capabilities

Search Type	Pattern	Example	Match Type	Expected Results
By UID (with separators)	CHE-XXX.XXX.XXX	`CHE-408.600.128`	Exact	Single company (1 result)
By UID (without separators)	CHEXXXXXXXXX	`CHE408600128`	Exact	Single company (1 result)
By Name	Text string (min 3 chars)	`"Nestlé"`	Fuzzy	Multiple results

Search Performance: Use UID-based searches for best performance and exact matching. Name searches query the Zefix API and may return multiple results. UID searches are automatically normalized to the canonical dotted format (CHE-XXX.XXX.XXX) before querying Zefix.

Search uses live Zefix API lookups. Both identifier and name searches query the Zefix REST API in real-time. Name searches require a minimum of 3 characters and a maximum of 100 characters.

Quirks & Gotchas

Quirk	Details
UID format matters for profile	For `companyProfile`, only `CHE123456789` (no separators) is accepted. For search, both `CHE-123.456.789` and `CHE123456789` work.
Multi-language company names	Swiss companies can be registered in German, French, Italian, or Romansh. The `legalForm.localName` reflects the registration language. Translated names appear in `commercialNames`.
All activity codes are AI-inferred	Zefix provides only a free-text activity description (Zweck / But / Scopo), not structured codes. Both NACE and ISIC are always AI-inferred. `isAIInferred` is always `true`.
Legal representatives are AI-parsed	Extracted from SOGC publication texts using AI. Companies without SOGC publications will have no legal representative data. Role classification as legal representative vs. other key person is AI-determined.
No shareholder data	Swiss commercial register does not publish structured shareholder data publicly.
No UBO data	Ultimate beneficial owner data is not publicly accessible in Switzerland.
26 cantonal registers, 2 technical platforms	22 cantons use chregister.ch; 4 cantons (FR, GE, NE, VD) use HRC Modern. Trade register extracts are always issued by the relevant canton.
Deletion date = closure	When a company has a `deletionDate` in Zefix, it is mapped to Closed status. The deletion date is used as the closure date.
eCH-0097 legal form standard	Swiss legal forms use the eCH-0097 national data standard. All 35 codes are deterministically mapped to ISO 20275 ELF codes (no AI inference for legal forms).
Capital in CHF	Most Swiss companies report capital in CHF (Swiss Francs), though some may use EUR or other currencies. The `capital.currency` field reflects the actual currency.
SOGC multilingual publications	SOGC publications may be in German, French, Italian, or mixed languages. The AI parser handles all three official languages.
Status “BEING_CANCELLED”	Zefix has a third status value for companies in the process of being dissolved (in Liquidation). This is mapped to active status with appropriate details.

Mappings

Company Status

Company status is determined deterministically from Zefix data. No AI inference is involved.

Zefix Status	English	Standardized Status	Notes
`ACTIVE`	Active	Active	Company is currently active
`BEING_CANCELLED`	Being cancelled / In liquidation	Active	Company is in the process of dissolution; still legally active
`CANCELLED`	Cancelled / Deleted	Closed	Company has been deleted from the register

When a company has status CANCELLED and a deletionDate is present, the deletion date is used as the closureDate in the statusDetails response. The BEING_CANCELLED status corresponds to companies undergoing liquidation proceedings.

Legal Forms

Switzerland uses the eCH-0097 data standard (Datenstandard Unternehmensidentifikation) for legal form classification. The system maps all 35 eCH-0097 codes deterministically to ISO 20275 (ELF) codes and standardized forms. No AI inference is involved for legal forms.

Multilingual legal form names: Swiss legal form names from Zefix come in the registration language of the company (German, French, Italian, or English). The legalForm.localName reflects this. The eCH-0097 code is used for deterministic mapping regardless of language.

The full eCH-0097 specification is available at eCH. ISO 20275 ELF codes are maintained by GLEIF. All 35 Swiss legal form codes are deterministically mapped, so no AI enrichment is needed for legal forms.

Legal Representatives

Legal representatives are extracted from SOGC publications (Swiss Official Gazette of Commerce). Zefix does not provide structured legal representative data; extraction relies on AI parsing of SOGC publication texts, which may be in German, French, Italian, or mixed languages.

Executive & Management Roles

Local Role (German)	Local Role (French)	Local Role (Italian)	English Translation
Geschaftsfuhrer	Gerant	Gerente	Managing Director
Direktor	Directeur	Direttore	Director

Board of Directors Roles

Local Role (German)	Local Role (French)	Local Role (Italian)	English Translation
Prasident des Verwaltungsrates	President du conseil d’administration	Presidente del Consiglio d’amministrazione	Chairman of the Board
Vizeprasident des Verwaltungsrates	Vice-president du conseil d’administration	Vicepresidente del Consiglio d’amministrazione	Vice Chairman of the Board
Mitglied des Verwaltungsrates	Membre du conseil d’administration	Membro del Consiglio d’amministrazione	Board Member

Authorized Signatories

Local Role (German)	Local Role (French)	Local Role (Italian)	English Translation
Prokurist	Fonde de procuration	Procuratore	Authorized Signatory

Signature types documented in SOGC publications:

mit Einzelzeichnung / avec signature individuelle / con firma individuale = individual signature rights
mit Kollektivzeichnung zu zweien / avec signature collective a deux / con firma collettiva a due = joint signature rights (two jointly)

Special Roles

Local Role (German)	Local Role (French)	Local Role (Italian)	English Translation
Liquidator	Liquidateur	Liquidatore	Liquidator
Gesellschafter	Associe	Socio	Partner

The classification of each role as legal representative or other key person is AI-determined based on the company’s legal form context. For example, a “Verwaltungsrat” (Board Member) is typically a legal representative for an AG (corporation), while a “Prokurist” (Authorized Signatory) may or may not be depending on the context. Both individuals and corporate entities can hold roles.

Representation Mode

Legal representatives extracted from SOGC publications include a representationMode field indicating signing authority:

{ mode: "sole" }: Can sign alone (“mit Einzelzeichnung” / “avec signature individuelle” / “con firma individuale”)
{ mode: "joint", minimumSignatories: 2 }: Must sign jointly with one other (“mit Kollektivzeichnung zu zweien” / “avec signature collective à deux” / “con firma collettiva a due”)
{ mode: "joint", minimumSignatories: N }: Must sign jointly with a specified number of others
null: No signing authority explicitly stated in the SOGC publication

The field is extracted via AI parsing from the trilingual SOGC publication text (German, French, Italian).

Other Key Persons

SOGC publications may also contain references to:

Role Type	Examples	Notes
Auditors	Revisionsstelle / Organe de revision / Ufficio di revisione	Statutory auditor companies; referenced in Zefix via `auditCompanies`
Former officers	Persons marked as “ausgeschieden” / “demissionnaire” / “dimesso”	Resigned or removed; extracted with `endDate` but excluded from current representatives

Shareholders

Shareholder data is not currently available for Swiss companies. The Swiss commercial register (Zefix) and SOGC publications do not provide structured shareholder or ownership data in a programmatically accessible format.

Aspect	Details
Availability	Not available
Reason	Swiss commercial register does not publish structured shareholder data publicly
Workaround	Shareholder information may appear in SOGC publication texts for some legal forms (e.g., GmbH partner lists), but is not systematically extracted

Activity Code Mapping

Switzerland does not use a national activity code classification in the Zefix registry. Activity codes are AI-inferred from the company’s purpose (Zweck / But / Scopo) field, which is a free-text description of the company’s business activities.

Activity Description (free text) → NACE Rev. 2 (AI-inferred) → ISIC Rev. 4 (AI-inferred)

Classification	Source	Example	AI Inferred?
NACE	Derived from activity description via AI	`62.01`	Yes (always)
ISIC	Derived from activity description via AI	`6201`	Yes (always)

Both NACE and ISIC codes are always AI-inferred for Swiss companies because the Zefix registry provides only a free-text activity description, not structured activity codes. The isAIInferred flag is always true for Swiss activity codes.

Data Source Priority & Routing

For a given entity, all company profile data comes from Zefix. There is no multi-source priority chain or fallback logic. Legal representatives come separately from SOGC publications via AI parsing.

Source Routing:

Company data (name, status, legal form, address, capital, purpose, identifiers): Zefix API (live query via REST API)
Legal representatives: SOGC publications (AI-parsed from combined SOGC text messages available via Zefix)
Activity codes: AI-inferred from the free-text purpose field
Legal form standardization: Deterministic eCH-0097 to ISO 20275 mapping (AI only used as fallback if eCH-0097 code is not in the mapping table)
Status enrichment: AI-enriched for detailed status information
