    How do I look up and validate a VAT number in Czech Republic?

    Validate a Czech Republic VAT number for free using the EU VIES service at https://ec.europa.eu/taxation_customs/vies/. VIES returns "valid" plus the legal name and address on file. Cross-check the same entity in ARES for the underlying registration number.

    Step-by-step

    1. 1

      Open the EU VIES portal

      Go to https://ec.europa.eu/taxation_customs/vies/. VIES is the European Commission's official VAT verification service.

    2. 2

      Select Czech Republic as the member state

      Choose the country code, then enter the VAT number without the country prefix.

    3. 3

      Read the response

      A "valid" response with legal name and address means the VAT number is genuinely registered. "Invalid" means it is not, or the trader has been de-registered.

    4. 4

      Cross-check in ARES

      For the underlying company registration number and status, search the same entity in ARES at https://ares.gov.cz.

      Save the timestamp

      Keep the VIES timestamp for your records — this is the evidence tax authorities accept for reverse-charge invoicing.

    Frequently asked questions

    Is checking a Czech Republic VAT number free?

    Yes — the EU VIES service at https://ec.europa.eu/taxation_customs/vies/ is free, official, and does not require registration.

    What does an invalid VIES response mean for a Czech Republic VAT number?

    It means the VAT number is not currently registered for intra-EU trade — either it was never valid, was de-registered, or is only registered for domestic transactions.
