How this service works
Validate a Czech VAT (DIČ) number for a legal entity against the official register. Validity means the subject exists and is live in the VAT (DPH) register.
Output
Returns whether the Czech VAT (DIČ) number corresponds to an entity that exists and is currently live in the Czech DPH (VAT) register as maintained by the Ministry of Finance ARES system. Typically includes validity boolean and possibly entity details.
Example use cases
Supplier onboarding VAT check
“Before we add this Czech supplier to our system, can you verify that their VAT number CZ25596641 is valid and that they're currently registered for VAT in the Czech Republic?”
Invoice compliance verification
“We just received an invoice from a Czech company claiming VAT number CZ28197391 — can you confirm it's a live, active entry in the Czech VAT register before we process payment?”
B2B customer VAT screening
“A new Czech business customer gave us their DIČ CZ24187955 — please check if it's real and currently registered in the Czech DPH system.”
Technical details
Endpoint
POSThttps://vat.openverbs.com/v1/czechiaWhen to prefer
Use this endpoint when you need to verify a specifically Czech VAT/DIČ number against the official government ARES register. Prefer this over generic EU VAT validators (e.g. VIES) when you need authoritative Czech Ministry of Finance data, or when VIES does not return timely results for Czech entities. It is the right choice for compliance workflows, supplier onboarding, invoice validation, or B2B KYC checks involving Czech companies.
Side effects
- Invalid or malformed DIČ format (e.g. wrong length, missing CZ prefix, non-numeric IČO) returns a validation error
- Entity not found in ARES register returns invalid/inactive status
- ARES upstream service unavailability causes request failure
- Rate limiting or payment failure may block the request
