An online gambling licence requires a mandatory physical connection to the Belgian territory: only those operators licensed to operate in the real world (and holding a principal A, B or F1 licence) can obtain a licence to offer the same games of chance and bets online (an additional A+, B+ or F1+ online licence).
Indeed, Article 4, Section 1 of the Games of Chance Act stipulates that it is unlawful for any person to operate games of chance (including betting) or a gaming establishment, in any form, at any place and in any direct or indirect manner, without a licence granted by the Gaming Commission.
