Here are the top digital-billboard locations and high-impact DOOH inventories in Belgium, with why they matter and sources/operators you can contact or buy through.

1. Brussels — city centre (Rue Neuve, Boulevard Anspach / De Brouckère, Place Louise, Porte de Namur, Rue de la Loi / European District) — highest footfall, tourist & shopping core and EU institutions (prime for brand awareness). (clearchannel.be)

2. Brussels Airport (BRU) — large captive audience of international travellers; JCDecaux runs major digital inventory and programmatic options at the airport. (jcdecaux-belux.com)

How to buy / next steps (quick):

• National operators: JCDecaux Belgium, Clear Channel Belgium, blowUP media Benelux, Lijncom (Antwerp) — contact them for availability and local pricing. (jcdecaux.com)
• Programmatic / self-serve options: JCDecaux via VIOOH, Clear Channel via LaunchPAD, and marketplaces like Glooh offer curated access to premium Belgian DOOH inventories. Use these for fast, targeted buys and real‑time scheduling. (jcdecaux.com)

If you’d like, I can:

• Build a short prioritized shortlist (e.g., 3–5 exact panel IDs or streets) based on your campaign goal (reach vs. targeting vs. creative impact), or
• Pull available inventory & estimated CPMs on one of the programmatic platforms (VIOOH / Glooh / LaunchPAD).

(If you want me to proceed with either option, tell me: campaign objective, city or national, budget range, and desired dates.)
