How to search the ARES
- 1
Access the ARES portal
Visit the official ARES (Administrativní registr ekonomických subjektů) website managed by the Ministry of Finance. This platform acts as a centralized gateway to multiple source registers.
- 2
Search by Identification Number (IČO)
Enter the 8-digit IČO number into the search field. This is the most reliable way to identify a specific entity. If the IČO is unknown, search by legal name, but be aware of possible phonetic matches.
- 3
Verify Data Source and Legal Form
Review the basic data summary. ARES aggregates data from the Commercial Register (OR), Trade Register (RŽP), and the Register of Non-profit Entities. Cross-reference the legal form (e.g., s.r.o. or a.s.) to confirm the entity type.
- 4
Access Documentation via Public Register
For more detailed history or financial statements, use the provided link to the 'Veřejný rejstřík' (Public Register) to access the 'Sbírka listin' (Collection of Documents).
Who uses this data
Due diligence analysts, tax compliance officers verifying VAT registration status, supply chain managers monitoring Czech vendors, and legal teams investigating beneficial ownership via the integrated source links.
Access, fees & notes
ARES is an aggregator; while highly reliable, in the event of a discrepancy, the data in the primary source register (like the Commercial Register) takes legal precedence.
Cost & access
Electronic search and basic data viewing are free of charge. Full historical documents are also freely available in PDF format via the linked Public Register.
Local-language glossary
- Identifikační číslo osoby (IČO)
- A unique 8-digit identification number assigned to every legal entity or sole trader in the Czech Republic.
- Daňové identifikační číslo (DIČ)
- The tax identification number used for VAT purposes, typically consisting of the prefix CZ followed by the IČO.
- Společnost s ručením omezeným (s.r.o.)
- The most common form of limited liability company in the Czech Republic.

Common mistakes to avoid
✗ Confusing the IČO with the DIČ when searching.
✓ Always use the 8-digit IČO for the primary identity search; the DIČ is specifically for tax and VAT verification.
✗ Assuming ARES data is a certified legal transcript.
✓ ARES is an informative database. For official legal proceedings or banking requirements, obtain a 'Výpis z obchodního rejstříku' from a Czech Point or the official portal.
Frequently Asked Questions
What is an IČO?▾
IČO (Identifikační číslo osoby) is an 8-digit identification number assigned to every economic subject in the Czech Republic. It's the primary identifier for all business interactions with government and other businesses.
What is an s.r.o.?▾
s.r.o. (Společnost s ručením omezeným) is the Czech limited liability company, equivalent to a GmbH. Since 2014, minimum share capital is CZK 1 (previously CZK 200,000), making it very accessible. It's the most common Czech business form.
How do I access Czech company data?▾
ARES (ares.gov.cz) provides free access to business registration data. The Commercial Register (justice.cz) provides more detailed information including articles of association, annual reports, and ownership structure.
Is Czech company financial data available?▾
Yes. Czech companies must file financial statements with the Commercial Register, where they are publicly accessible. The Sbírka listin (Collection of Documents) contains founding documents, annual reports, and other filings.
How do I search for a company in Czech Republic by name?▾
Use the available lookup or the linked official ARES service. Start with the legal name, then compare the exact IČO number and available identity fields. Name matches are candidates; source coverage and partial-name support vary.
Is the Czech Republic company register free to search?▾
Basic company lookup is free on LemReveal. The official Czech Republic register has independent access rules and may require an account or charge for searches, extracts or particular documents. Check the source's current terms.
Can I search Czech Republic companies by registration number?▾
Where the source supports it, use the exact IČO number together with its register or jurisdiction. Preserve prefixes and leading zeros and compare the returned legal name. A number alone does not guarantee coverage or a successful lookup.
How do I check whether a company is registered in Czech Republic?▾
Search the exact IČO number or legal name above, then confirm the entity's identifier and source. An empty result can reflect coverage limits, a source outage, spelling or a different jurisdiction; it does not prove the business is unregistered. A fuzzy candidate is not a confirmed identity.
How can I tell if a Czech Republic company is still active?▾
Read the status and effective date where the ARES supplies them. Active registration does not establish trading or financial health. Monitoring is available only for supported sources and confirmed records; verify the actual watch state.
How do I find a company's IČO number?▾
Identify the legal entity using the available lookup or official ARES route. Record the IČO only where supplied, with its source and jurisdiction. Do not infer missing identifiers from a similar name.
