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

    Validate a Austria 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 Firmenbuch 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 Austria 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 Firmenbuch

      For the underlying company registration number and status, search the same entity in Firmenbuch at https://www.justiz.gv.at.

    Frequently asked questions

    Is checking a Austria 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 Austria 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.

    Can I look up a Austria VAT number from a company name?

    VIES doesn't support name search. Use Firmenbuch (https://www.justiz.gv.at) to find the company's VAT number by name, then validate it on VIES.

    The Firmenbuch is the official public register of companies incorporated in Austria. It is operated by the government and is the primary source cited on this page — https://ec.europa.eu/taxation_customs/vies/.

    How do I check if a Austria VAT number is valid?

    A Austria VAT number always begins with the country's ISO code and is followed by the national numeric identifier. The exact length and check-digit rule depends on the country — see the format examples in the step-by-step above.
