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

    Validate an exact Poland 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 KRS / CEIDG.

    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 Poland 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 KRS / CEIDG

      For the underlying company registration number and status, search the same entity in KRS / CEIDG at https://ekrs.ms.gov.pl.

    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.

    Poland: choosing and checking the right record

    Choose the correct source
    Choose KRS for entities within the National Court Register and CEIDG for sole-trader registration. Use the official government search routes rather than assuming every Polish business must have a KRS record.
    Confirm the entity
    Keep KRS, NIP and REGON numbers distinct. Compare the full legal name and available address with the contracting entity. Read representation rules separately from the list of management-board members.

    Official KRS guidance

    Check current access and document options on the official KRS / CEIDG site. For search limitations and missing-result guidance, see the Poland registry guide.

    Frequently asked questions

    Is checking a Poland 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 Poland 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 Poland VAT number from a company name?

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

    Is the Poland company register free to search?

    Yes. Basic company lookups on the KRS / CEIDG 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 Poland business registry?

    The KRS / CEIDG is the official public register of companies incorporated in Poland. 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 Poland VAT number is valid?

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

    What does a Poland VAT number look like?

    A Poland 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.
