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

    Validate an exact Slovakia 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 RPO / Obchodný register.

    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 Slovakia 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 RPO / Obchodný register

      For the underlying company registration number and status, search the same entity in RPO / Obchodný register at https://www.orsr.sk.

    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 Slovakia 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 Slovakia 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 Slovakia VAT number from a company name?

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

    Is the Slovakia company register free to search?

    Yes. Basic company lookups on the RPO / Obchodný register 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 Slovakia business registry?

    The RPO / Obchodný register is the official public register of companies incorporated in Slovakia. 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 Slovakia VAT number is valid?

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

    What does a Slovakia VAT number look like?

    A Slovakia 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.
