Czechia - Topograph

Data Sources

Czechia uses multiple official registers orchestrated through ARES. For a given entity, data is assembled from ARES as the discovery layer, then enriched from the primary source register indicated by ARES. The primary source takes precedence for overlapping attributes.

Registers

ARES (Administrative Register of Economic Subjects) — Operated by the Ministry of Finance (ares.gov.cz), ARES is the central discovery layer for all Czech entities. It aggregates data from over a dozen underlying registers and provides: company name, legal form, registered address, activity codes (CZ-NACE), registration/dissolution dates, tax identifiers (DIC/DPH), and registration statuses across all connected registers (VR, RZP, DPH, IR, etc.). ARES also indicates a primary data source per entity (primarniZdroj), which drives the orchestration strategy.
VR (Commercial Register) — The Obchodni rejstrik, operated by the Ministry of Justice (or.justice.cz). Contains detailed data for legal entities registered in the commercial register: legal name, registered address, share capital, legal form, business purpose, legal representatives (Statutarni organ), shareholders (Spolecnici), and dissolution/deletion information. Data is extracted by parsing HTML pages (no structured API is available).
RZP (Trade Licensing Register) — The Rejstrik zivnostenskeho podnikani (rzp.gov.cz). Contains business license data primarily for sole traders and licensed businesses: legal name, registered address, registration date, and licensed activities. Accessed via a session-based XML API. Also the source for Trade Register Extract PDF documents.
ESM (Evidence of Beneficial Owners) — The Evidence skutecnych majitelu (esm.justice.cz). Contains Ultimate Beneficial Owner (UBO) data: names, birth dates, nationalities, residence addresses, ownership percentages, voting rights, and control nature (direct/indirect). Data is extracted by parsing HTML pages. Currently implemented but not yet exposed as a standalone datapoint (commented out in workflow configuration).

ARES is the orchestration hub. Every company profile request starts with ARES for discovery and base attributes. ARES indicates a primary source per entity (vr, rzp, or others), and the system fetches complementary data from that source. If the primary source fetch fails, available data from ARES alone is used. If no primary source is indicated, both VR and RZP are queried in parallel (best-effort).

How does the multi-source orchestration work?

ARES is always queried first to discover the entity and get base attributes (name, address, legal form, activity codes, identifiers, status)
ARES indicates a primary source (primarniZdroj):
- vr — Commercial Register: the system fetches VR data (legal reps, shareholders, capital, status, legal form) and merges it into the ARES base
- rzp — Trade Licensing Register: the system fetches RZP data (name, address, registration date, activities) and merges it
- Other/null — both VR and RZP are queried in parallel, and any available data is merged
For overlapping attributes (e.g., legal name, address), the primary source takes precedence over ARES
AI enrichment is applied as a final step: activities get ISIC codes, status gets standardized classification, legal form gets ISO 20275 codes

Company Identifiers

Query Identifiers

Company Type	Source	Format	Example	Notes
All entities	ARES	8 digits (ICO)	`21110365`	Spaces are stripped (e.g., `19188 889` becomes `19188889`)

ICO Format: The ICO (Identifikacni cislo osoby) is always 8 digits. Input with spaces is tolerated — they are automatically stripped before processing.

Identifiers in API Response

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

Identifier Type	Format	Example	Found In
`ico`	8 digits	`21110365`	All entities
`dic`	CZ + 8-10 digits	`CZ21110365`	Tax-registered entities (normalized with CZ prefix)
`vat`	CZ + 8-10 digits	`CZ21110365`	Only when ARES confirms active DPH (VAT) status

VAT vs DIC: The dic (Tax Identification Number) is always returned when available. The vat identifier is only set when ARES confirms the entity has active DPH (VAT) registration status. We do not synthesize VAT from ICO or query the DPH register separately. For sole traders and individuals, the VAT number may have 9-10 digits and can differ from the ICO.

Search Capabilities

Search Type	Pattern	Example	Match Type	Expected Results
By ICO	8 digits	`21110365`	Exact	Single company (1 result)
By ICO (with spaces)	Digits with spaces	`19188 889`	Exact	Single company (spaces stripped)
By Name	Text string (2-200 chars)	`"PalmApp Tech s.r.o."`	Contains/partial	Multiple results (up to 30)

Search Performance: Use ICO-based searches for best performance and exact matching. Name searches query ARES and may return up to 30 results. If a name search returns too many results, ARES will return an error suggesting a more specific search term.

Unsupported search inputs: DIC and VAT numbers are not supported as search inputs. Only ICO and company name searches are available.

Company Status

Company status is determined from ARES registration statuses across multiple registers (VR, RES, RZP, DPH, IR). The logic is deterministic — no AI inference is involved for status determination. AI enrichment is applied afterward for standardization only.

Status Determination Logic

Condition	Local Status	Standardized Status	Notes
Active in any register (VR, RES, DPH, RZP)	Active	Active	Any active registration means the entity is active
In liquidation (VR or RES shows `V LIKVIDACI`)	In Liquidation	Active	Treated as active — entity still exists
Insolvency register (IR) active AND entity active	Under Insolvency Proceedings	Under Insolvency Proceeding	Reflects proceedings, not outcome
VR or RES shows `ZRUSENY` (and not active elsewhere)	Dissolved	Closed	Entity has been removed from register
RES cessation date (`datumZaniku`) present	Dissolved	Closed	Overrides all other signals
None of the above	Unknown	Unknown	Insufficient data to determine status

Closure Reasons (from VR)

When a company is dissolved, the closure reason is determined by parsing Czech legal text from the Commercial Register:

Czech Pattern	Standardized Closure Reason
konkurs / konkurz / insolvence / upadek	Bankruptcy
fuze / slouceni / splynut	Merger
prevod jmeni na jedineho spolecnika/akcionare	Acquisition
zrusena s likvidaci (rozhodnutim valne hromady)	Voluntary Dissolution
zrusena s likvidaci (general)	Liquidation
zrusena dle paragrafu / ex lege	Administrative Dissolution
rozhodnutim soudu / usneseni soudu	Court Order
Other patterns	Other

VR closure reasons are extracted by pattern-matching normalized (diacritics-stripped) Czech text from the Commercial Register’s “Ostatni skutecnosti” (Other facts) and insolvency sections. If no specific pattern matches, the closure reason defaults to “Other.”

Legal Forms

Czechia uses a deterministic legal form mapping via the ARES “Právní forma” codelist. The mapping provides the local Czech name and an English translation for each code. For known codes, standardized classification is applied directly; for unrecognized codes, AI-based classification is used as fallback. ISO 20275 (ELF) codes will be populated in a future update.

Legal forms are classified from official registry data. For known codes, standardized classification is applied directly; for unrecognized codes, AI-based classification is used as fallback.

Legal Representatives

Legal representatives are extracted from the Commercial Register (VR) under the Statutarni organ (Statutory body) section. Data is obtained by parsing the VR HTML pages.

Extraction Details

Source: VR (or.justice.cz) HTML pages, specifically the Statutarni organ section
Role detection: Currently extracts persons with the Jednatel (Managing Director) role label
Data extracted per person: Full name, birth date (day/month/year), residential address, function start date (Den vzniku funkce), function end date (Den zaniku funkce)
Role mapping: Jednatel is mapped to Managing Director (standardized)

Czech Role	English Translation	Standardized Role
Jednatel	Managing Director	Managing Director

Current limitation: The VR parser specifically looks for the Jednatel label in the statutory body section. Other statutory roles (e.g., board members in a.s. companies, Clen predstavenstva, Predseda predstavenstva) may not be extracted in all cases. Legal representatives are only available for entities registered in the Commercial Register (VR).

Other Key Persons

Other key persons (such as supervisory board members and controllers) are extracted from ARES when available. These are persons associated with the company who are neither legal representatives nor shareholders.

Other key persons data availability depends on the entity type and the primary register source. Not all companies have other key persons in their register records.

Shareholders

Shareholders are extracted from the Commercial Register (VR) under the Spolecnici (Partners) section. Data is obtained by parsing the VR HTML pages.

Extraction Logic

Section detection: The parser looks for Spolecnici (Partners) or Akcionar (Shareholder) headers in the VR HTML
Sole shareholder: When the section header contains Jediny (Sole), the shareholder is assigned 100% ownership if no explicit percentage is found
Multiple shares: If a shareholder has multiple entries/shares, they are summed into a single aggregate stake
Corporate vs individual: Determined by presence of ICO number or legal form suffix (a.s., s.r.o., etc.)

Ownership Data

Field	Description	Source
`sharePercentage`	Ownership percentage (from `Obchodni podil`)	VR (Commercial Register)
`nominalCapitalHeld`	Capital contribution amount in CZK (from `Vklad`)	VR (Commercial Register)
`type`	Individual or Company	Determined from register data (ICO presence, legal form suffix)

Shareholder data is primarily available for s.r.o. (Limited Liability Companies) registered in the Commercial Register (VR). Joint-stock companies (a.s.) do not list individual shareholders in the public register. Both individual and corporate shareholders are supported.

Activity Code Mapping

Czechia uses the CZ-NACE classification, which is the Czech adaptation of the European NACE Rev. 2 standard. The system maps activity codes across three levels:

CZ-NACE (Czech) -> NACE Rev. 2 (European) -> ISIC Rev. 4 (International)

Classification	Source	Example	AI Inferred?
CZ-NACE	ARES (`czNace` field)	`62.01`	No (official)
NACE	Same as CZ-NACE (identical codes)	`62.01`	No (formal mapping)
ISIC	Derived from NACE or AI-inferred	`6201`	Sometimes

AI Enrichment: When ISIC codes cannot be derived from NACE via formal mapping tables, the system uses an LLM to match activity descriptions to ISIC Rev. 4 codes. Every activity item includes an isAIInferred flag to distinguish official vs. AI-derived codes. CZ-NACE and NACE codes are never AI-inferred.

Activity Codes by Source

Source	Classifications Returned	Notes
ARES	CZ-NACE (as NACE) + ISIC	From `czNace` field, multiple codes per entity
VR	Activity description text	Free-text `Predmet podnikani` (business purpose)
RZP	Activity description text	Licensed activities from trade register XML

Legend: Yes = Available | No = Not Available | Limited = Conditionally Available | Async = Asynchronous processing

Documents by Company Type

All Entity Types (Companies & Sole Traders)

Document Type	API Category	Format	SKU	Availability	Notes
Trade Register Extract	`tradeRegisterExtract`	PDF	`CZE_TRADE_REGISTER_EXTRACT`	Yes	Extract from the Trade Licensing Register (RZP)

The Trade Register Extract is sourced from the Trade Licensing Register (RZP) via a session-based XML API. It contains current business license and registration information. The document is retrieved by: (1) starting an RZP session, (2) searching for the subject by ICO, (3) fetching an intermediate ISVS XML that contains the link to the final PDF, and (4) downloading the PDF. The document has a 1-day TTL (time-to-live) cache.

Data Source Priority & Routing

For a given entity, data is assembled from multiple sources with a clear precedence hierarchy. ARES provides the base, and the primary source register enriches it.

Orchestration Flow:

ARES — Always queried first (30s timeout, 3 retries). Provides base attributes: name, address, legal form, activities, identifiers, status
Primary source — Determined by ARES primarniZdroj field:
- vr — VR is fetched (1m timeout, 2 retries). Provides: legal reps, shareholders, capital, status override, legal form, activity description
- rzp — RZP is fetched (1m timeout, 2 retries). Provides: name, address, registration date, activity descriptions
- Other/null — Both VR and RZP are queried in parallel (best-effort). Any available data is merged
AI Enrichment (2m timeout, no retry) — Applied in parallel for:
- Activities: ISIC codes via vector matching + formal derivation
- Status: Standardized classification
- Legal form: ISO 20275 codes

Merge behavior: The primary source takes precedence over ARES for overlapping attributes. If a primary source fetch fails, ARES data alone is used (graceful degradation).

Attribute-Level Source Mapping

Attribute	Primary Source	Fallback	Notes

    },
    "legalAddress": { "addressLine1": "Husova 12", "city": "Brno", "postalCode": "60200", "countryCode": "CZ" }
  }
}

Note: Sole traders (RZP primary source) do not have legal representatives, shareholders, or capital data. The legal name is the individual’s name. Activity description comes from licensed activities in the RZP.

Entity In Liquidation

    "legalAddress": { "addressLine1": "Karlova 8", "city": "Praha", "postalCode": "11000", "countryCode": "CZ" }
  }
}

Note: Entities in liquidation are treated as active (active: true) with local status “In Liquidation.” The entity still legally exists during the liquidation process.

Onboarding Profile (Source: Batch Cache)

{
  "company": {
    "id": "04234651",
    "countryCode": "CZ",
    "identifiers": { "ico": "04234651" },
    "legalName": "AUTOBAZARNV, s.r.o.",
    "registrationDate": "2015-07-08",
    "status": { "localName": "Aktivní", "active": true, "statusDetails": { "status": "ACTIVE" } },
    "legalForm": { "localName": "112" },
    "activities": {
      "NACE": [{ "code": "45200" }]
    },
    "legalAddress": { "addressLine1": "294", "city": "Polnička", "postalCode": "59102", "countryCode": "CZ" }
  }
}

Note: Onboarding profiles are served from the batch staging table. No AI enrichment — no standardized or iso20275Code on legal form. Legal form localName is the numeric code from ARES (e.g., "112" = s.r.o.).

Available Documents

Documents are returned when "dataPoints": ["availableDocuments"] is requested.

API Category	Document	Notes
`tradeRegisterExtract`	Trade Register Extract (RZP) PDF	Available for all entities with an ICO

Batch Cache

Czech company data is batch-synced from the ARES open dataset into a local cache (Meilisearch + PostgreSQL staging table).

Search

Search queries hit the Meilisearch cache first for instant results, with automatic fallback to the live ARES API if the cache misses.

Companies in Cache

The cache contains all non-terminated Czech entities from ARES. The filtering is based on the dissolution date:

Condition	Included?	Description
`datum_zaniku` IS NULL	Yes	Entity has not been dissolved
`datum_zaniku` IS NOT NULL	No	Entity has been dissolved/terminated

This means active entities, entities in liquidation, and entities under insolvency proceedings are all included; only fully terminated entities (with a recorded dissolution date) are excluded.

Onboarding Mode

In onboarding mode, requests for the company datapoint read directly from the staging table (cz.ares), not the live ARES API. This provides faster, cheaper responses with no AI enrichment overhead. Data freshness depends on the batch sync schedule.

Quirks & Gotchas

Quirk	Details
Multi-source orchestration	Data is merged from up to three sources (ARES, VR, RZP). The primary source indicated by ARES takes precedence for overlapping attributes. If a source fetch fails, available data from other sources is used (graceful degradation).
ICO spaces are stripped	Input ICOs may contain spaces (e.g., `19188 889`) which are normalized to `19188889` before processing.
VAT only for active DPH registrants	The `identifiers.vat` field is only set when ARES confirms active DPH (VAT) status. We do not synthesize VAT from ICO or query the DPH register separately.
Shareholders only for s.r.o.	Shareholder data with ownership percentages is only available for Limited Liability Companies (s.r.o.) in the Commercial Register. Joint-stock companies (a.s.) do not list shareholders publicly.
ISIC codes may be AI-inferred	CZ-NACE codes from ARES are official. ISIC codes are derived via formal mapping when possible, with AI fallback. Check the `isAIInferred` flag.
Closure reasons from register text	When a company is dissolved, the closure reason is determined by pattern-matching normalized Czech text from the VR “Ostatni skutecnosti” and insolvency sections (e.g., bankruptcy, merger, acquisition, liquidation, court order).
VR HTML parsing	The Commercial Register (justice.cz) does not provide a structured API. Data is extracted by parsing HTML pages, which may occasionally miss fields if the page structure changes.
Legal form mapping is deterministic	Czech legal forms are mapped deterministically using the `ARES_LEGAL_FORM_MAPPING` codelist (140+ forms). ISO 20275 codes are added via AI enrichment.
UBO data implemented but not exposed	Ultimate Beneficial Owners from ESM (Evidence of Beneficial Owners) is fully implemented in activities but the standalone UBO datapoint is currently commented out in the workflow configuration. UBOs from ARES are returned when available as part of the company profile.
In Liquidation = Active	Entities with status “V LIKVIDACI” in VR or RES are treated as active (`active: true`) because the entity still legally exists during the liquidation process.
RZP uses session-based API	The Trade Licensing Register requires starting a session before any data requests. Sessions may timeout, requiring retry logic.
Capital in CZK only	Share capital from the VR is always expressed in Czech Koruna (CZK) with formatted strings using Czech locale (e.g., `200 000 Kc`).
Sole shareholder default to 100%	When the VR HTML indicates a `Jediny spolecnik` (sole partner) section and no explicit ownership percentage is found, the system defaults the shareholder to 100% ownership.
