    How do I look up a company by its registration number in Spain?

    Use the exact NIF with its issuing jurisdiction or register on Registro Mercantil Central. Compare the returned legal name and identifier. A valid-looking number does not guarantee a result: coverage, formatting, access and source availability affect the lookup.

    Step-by-step

    1. 1

      Find the NIF on the paperwork

      The NIF normally appears on invoices, contracts, the website footer or official correspondence. It is the number counterparties are required to quote.

    2. 2

      Search the NIF

      Preserve leading zeros, letters, court and jurisdiction information. Follow the source's documented format rather than removing meaningful parts to force a match.

    3. 3

      Confirm the returned entity

      Check the legal name on the returned record matches the name on your paperwork. A mismatch between quoted number and quoted name is a serious warning sign.

    4. 4

      Verify at Registro Mercantil Central

      For anything contractual, confirm the number against the primary source at https://www.rmc.es.

    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.

    Frequently asked questions

    What is a NIF in Spain?

    It is the identifier Registro Mercantil Central assigns to a registered entity. It stays with the entity even if the trading name changes, which makes it the reliable way to track a company over time.

    Is a NIF lookup free?

    LemReveal's basic lookup is free where supported. Check Registro Mercantil Central's official access rules for the record or document required.

    What if the NIF returns no result?

    Check the format, issuing jurisdiction, coverage and source availability. Preserve meaningful prefixes and leading zeros. An unavailable source is not a confirmed absence; ask the counterparty to clarify the identifier.

    Should I use the NIF or the company name?

    The NIF. Names are duplicated across entities within a group; the number is unique to one entity.

    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.
