How to use Kausate in Czechia — what you can call, which identifiers it uses, and which documents you can order

Needed for some operations

Company data here comes directly from ARES - Administrativní registr ekonomických subjektů, ISIR - Insolvenční rejstřík and Obchodní rejstřík.

What each operation does is the same everywhere and is explained on the jurisdictions overview.

How to search

Start with company search and jurisdictionCode: "cz". Pass the name as companyName. Czechia accepts no generic number alias — the fields below are its own.

Fields

To say exactly what you mean, send an advancedQuery instead. Czechia understands these fields:

Field	What it does
`name`	Company name to search for.
`includeDeleted` boolean	Also return companies struck off the Commercial Register, which ARES no longer lists, from the register itself.

Examples

{  "jurisdictionCode": "cz",  "advancedQuery": {    "name": "Skoda Auto"  }}

Czechia also accepts includeDeleted + name.

Company identifiers

Czechia has no number-based search: find a company by name, then use the kausateId search returns. These schemes label the values that come back in a company’s identifiers.

Identifier	Appears as	Format
Czech IČO Czech company identification number (Identifikační číslo osoby) - 8 digits	`cz_ico`	`^\d{8}$`
Czech DIČ (Tax ID) Czech tax identification number (Daňové identifikační číslo)	`cz_dic`	`^CZ\d{8,10}$`
Commercial Register Entry	`cz_commercial_register_entry`	No fixed format

Identifier notes

The Czech company identifier (IČO) is an 8-digit number that Kausate always returns zero-padded — many real IČOs start with one or more leading zeros (for example, 00177041 for Škoda Auto). If any part of your pipeline parses it as a number instead of keeping it as a string, you will silently drop the leading zeros and end up with a value that no longer matches the register.
For most Czech companies, the tax ID (DIČ) is not an independently assigned number — it is simply the literal prefix "CZ" followed by the same digits as the company's IČO. Don't build logic that treats the two as unrelated identifiers requiring cross-checks; for a standard VAT-registered company, a mismatch between them would itself be the anomaly worth investigating.

Documents you can order

Document	Order by	Status
Czech Annual Report Annual report/financial statement from Czech Commercial Register	A document ID from the list operation	Live
Czech Current Extract Current company extract from Czech Commercial Register	`register_extract` `register_extract_official` `shareholders_list`	Live
Czech Full Extract Full historical extract from Czech Commercial Register	`CZARFE`	Live

Documents with a shortcut are ordered directly by that name — for example register_extract. Those shown with a code have no cross-jurisdiction shortcut: order them by the code itself — for example CZARFE. The rest are filings whose availability differs per company: call list documents first and order the ID it returns.

Local notes

Gotchas

Trap	What happens
Sole proprietors excluded	Sole proprietors and other self-employed individuals (fyzická osoba) that exist in the underlying Czech registry are deliberately excluded from search results, and Kausate cannot retrieve a company report or documents for one — only companies and other legal entities (s.r.o., a.s., cooperatives, associations, etc.) are covered, because sole proprietors sit in a separate register that carries no filed documents. If you search for or look up a self-employed individual by their IČO, expect a not-found result rather than a report.
a.s. ownership is sparse	Joint-stock company (a.s.) shareholder data is often sparse or empty — the register doesn't require full disclosure for a.s. like it does for s.r.o. Expect ownership percentages and capital contributions for s.r.o. partners; a.s. shareholders often just names.
Document labels partly translated	Document type labels translate to English when recognized; unrecognized ones (including many compound labels) pass through as original Czech text — treat this as best-effort, not a fixed set.
Free-text closure status	A dissolved or closing company's original-language status text may not be generic "zaniklý"/"vymazaný" — it can be a free-text phrase like "fúze" (merger), "úpadek" (insolvency), "přeměna" (transformation), or "v likvidaci" (liquidation). Write logic against the normalized status field, not this text.

Glossary

Term	Meaning
`jednatel`	The statutory executive of a Czech s.r.o. (limited liability company) — equivalent to a managing director, and the role you'll typically see for whoever runs the company's day-to-day business.
`prokurista / prokura`	A person (or the authority itself) holding "prokura" — a formal signing authority to act on the company's behalf, which Kausate reports as its own distinct role separate from director- or board-level positions.
`likvidátor`	The liquidator appointed to wind up a company. Seeing this role listed means the company is in liquidation — actively being wound down — a stage that can precede, but is distinct from, final dissolution: Kausate's own status field keeps a company in liquidation marked as still active while it winds down.
`společník`	A member/quota-holder of an s.r.o. This denotes an ownership stake, not a management position, even though it's listed alongside officer roles in the company's data.
`aktivní / zaniklý / vymazaný`	The register's own status words: "aktivní" means active, while "zaniklý" and "vymazaný" both indicate the company has been dissolved or struck off the register.
