    How do I find a company's registration number in Spain?

    Search the company's name on Registro Mercantil Central at https://www.rmc.es. The result page shows its registration number — the same identifier that appears on invoices, contracts, and government filings.

    Step-by-step

    1. 1

      Open Registro Mercantil Central

      Navigate to https://www.rmc.es.

      https://www.rmc.es
    2. 2

      Search by company name

      Type the exact trading or legal name. Partial matches usually work; add the city if the name is common.

    3. 3

      Copy the registration number

      The registration number is displayed at the top of the entity profile. It is the authoritative ID for cross-referencing.

    4. 4

      Confirm it's the right entity

      Check the registered address and incorporation date to be sure you have the correct legal entity, especially for groups with similarly named subsidiaries.

    Spain: choosing and checking the right record

    Choose the correct source
    Start with the legal name, NIF and province. The Registro Mercantil Central and provincial registers have different functions; follow the official document route to the register holding the company's file rather than treating name availability as incorporation evidence.
    Confirm the entity
    CIF is the older name often used for a company's NIF. Compare the exact legal entity and province; an ES-prefixed VAT check answers a tax question and is not a replacement for the commercial-register entry.

    Check current access and document options on the official Registro Mercantil Central site. For search limitations and missing-result guidance, see the Spain registry guide.

    Frequently asked questions

    Where is a Spain company's registration number published?

    Look for the identifier on the entity's record or available extract in Registro Mercantil Central (https://www.rmc.es). Compare it with the counterparty's documentation; publication requirements and identifier labels vary by jurisdiction.

    Is looking up a Spain registration number free?

    LemReveal's basic lookup is free. Check Registro Mercantil Central's current access rules: an official portal can require an account, charge for searches or restrict particular documents.

    What is an SL in Spain?

    An SL (Sociedad Limitada) is a Spanish limited-liability company. The statutory minimum capital is €1. Special reserve and shareholder-liability rules apply while capital is below €3,000; check the registered capital and current legislation rather than treating a low amount as a registration defect.

    Is the Spain company register free to search?

    Yes. Basic company lookups on the Registro Mercantil Central 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 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://www.rmc.es.

    Where do I find a Spain company's registration number?

    Every registered Spain entity has a unique registration number issued at incorporation. It appears on invoices, contracts, the company's website footer (often in a "legal" section), and prominently on its Registro Mercantil Central record.

    Is a Spain registration number the same as a VAT number?

    No. The registration number is the identifier issued by the Registro Mercantil Central when the company was formed. The VAT number is a separate tax identifier issued (only if the company is VAT-registered) by the national tax authority. Many small companies have a registration number but no VAT number.
