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).

An A licence is required to operate a casino. In Belgium, the maximum number of A licences that can be granted simultaneously is set at 9. As such, 9 casinos can be operated in Belgium.
