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

    Validate an exact Austria VAT number using the free EU VIES service at https://ec.europa.eu/taxation_customs/vies/. VIES checks registration for intra-EU transactions; name and address availability varies. It is not a company-name search or a company-registration check. Cross-check the legal entity separately in Firmenbuch.

    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

      Record valid, invalid or service unavailable separately. Invalid can reflect non-activation for intra-EU transactions or a registration update, not just de-registration. Name and address may not be supplied by the national service.

    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.

    5. 5

      Save the timestamp

      Keep the queried country, VAT number, result, timestamp and consultation reference where supplied. Evidence requirements depend on the transaction and authority; this response alone is not tax advice.

    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 does not support name search. Ask the supplier for its VAT number and verify it. Firmenbuch can help identify the company, but do not assume its record includes a VAT number.

    Is the Austria company register free to search?

    Yes. Basic company lookups on the Firmenbuch are free — you can search by company name or registration number, view legal status, registered address and (usually) directors at no cost. Some jurisdictions charge a small fee only for downloading full filed documents.

    What is the official Austria business registry?

    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?

    Use the EU VIES service (ec.europa.eu/taxation_customs/vies/) or the Firmenbuch. Enter the VAT number without spaces and pick Austria from the country dropdown. A valid number returns the registered trading name and address; an invalid one returns "not valid".

    What does a Austria VAT number look like?

    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.
