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

    Use the exact KBO with its issuing jurisdiction or register on KBO. 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 KBO on the paperwork

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

    2. 2

      Search the KBO

      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 KBO

      For anything contractual, confirm the number against the primary source at https://kbopub.economie.fgov.be.

    Belgium: choosing and checking the right record

    Choose the correct source
    Use KBO/BCE Public Search to identify the enterprise and its establishment units. Open the enterprise record first, then inspect any establishment unit relevant to the address you were given.
    Confirm the entity
    Compare the enterprise number, legal name, legal form and status. Distinguish the enterprise from a local establishment; the latter can have a different address without being a different contracting entity.

    Check current access and document options on the official KBO/BCE site. For search limitations and missing-result guidance, see the Belgium registry guide.

    Frequently asked questions

    What is a KBO in Belgium?

    It is the identifier KBO 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 KBO lookup free?

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

    What if the KBO 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 KBO or the company name?

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

    What is a Belgian enterprise number?

    Every Belgian business receives a unique 10-digit enterprise number (formatted as 0XXX.XXX.XXX) from the KBO/BCE. This single number replaces the old VAT, commercial register, and social security numbers.

    What is the official Belgium business registry?

    The KBO/BCE is the official public register of companies incorporated in Belgium. It is operated by the government and is the primary source cited on this page — https://kbopub.economie.fgov.be.
