Specific requirements for Belgium
Ondernemingsnummer
Belgian businesses must display their ondernemingsnummer (enterprise number) on their website. Format: BE 0XXX.XXX.XXX.
GBA enforcement
The GBA (Gegevensbeschermingsautoriteit) enforces GDPR in Belgium. They have been active in cookie consent enforcement, including a landmark case against IAB Europe.
Bilingual requirements
Businesses in Brussels or serving both Dutch and French-speaking communities may need to provide information in both languages.
Enforcement in Belgium
The Belgian GBA's 2022 ruling against IAB Europe — fining them €250,000 for the Transparency and Consent Framework — sent shockwaves through the entire EU ad-tech industry. The GBA has also fined a Belgian company €50,000 for sending marketing emails without valid consent, and regularly publishes enforcement decisions to increase awareness.
