In Belgium, players can be denied access to real or virtual gaming establishments of class I and II and virtual gaming establishments of class IV for various reasons:

- To protect young people from the possible dangers of gambling. Access to real and virtual casinos and slot machine arcades is forbidden for people under the age of 21. The minimum age for both real and virtual betting offices is 18 years;

- Players can have themselves excluded from real and virtual casinos and slot machine arcades, and virtual betting offices when they think they have to be protected from themselves;

- In addition, an interested third party (e.g. the partner) can submit a request for exclusion to the Gaming Commission;

- Bans may be enforced pursuant to court decisions (e.g. for persons whose collective debt settlement notices have been deemed admissible);
- People can also be refused entry to a casino or slot machine arcade based on the nature of their profession - take, for example, magistrates, notaries, bailiffs and members of thepolice;
- The legal representative of a person under tutorship may request to the Belgian Gaming Commission by regular post the upholding of the precautionary gambling ban for the to be protected person whom he is responsible for (see Article 54 § 3.3 of the Act on games of chance).
Since 2004, Belgium has the Excluded Persons Information System (EPIS), an electronic system that bundles all excluded players. When entering a real or virtual casino or slot machine arcade, or a virtual betting office, it is mandatory to register the name, the first name and the date of birth of the player in EPIS to check whether he may be allowed to enter. This is undoubtedly a very powerful instrument in the fight against gambling addiction.
