What this check does and does not say

  • We compare against every name in the KBO register today: the name, the abbreviation and the trade names of enterprises and their establishments. Capitals, accents, punctuation and legal forms (bv, nv, srl, ...) do not count.
  • This is not a trademark search. A name can be free in the register and still be protected as a trademark. Trademarks are searched in the registers of the Benelux Office for Intellectual Property (BOIP, boip.int) and the European Union Intellectual Property Office (EUIPO, euipo.europa.eu).
  • A domain name or a social media handle is also separate from the register.
