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

    Validate a Spain 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 Registro Mercantil Central 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 Spain 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 Registro Mercantil Central

      For the underlying company registration number and status, search the same entity in Registro Mercantil Central at https://www.rmc.es.

      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 Spain 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 Spain 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 Spain VAT number from a company name?

    VIES doesn't support name search. Use Registro Mercantil Central (https://www.rmc.es) to find the company's VAT number by name, then validate it on VIES.

    Is the Spain company register free to search?

    What is the official Spain business registry?

    The Registro Mercantil Central is the official public register of companies incorporated in Spain. 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 Spain VAT number is valid?

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

    What does a Spain VAT number look like?

    A Spain 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.
