Getting a Belgian virtual phone number for your business
Brussels, Liège, Antwerp: Belgium is a key export market for many European SMEs. A +32 number spares you a foreign country code, which your Belgian prospects immediately identify as a call from abroad.
Belgium requires a local address in every case. For a landline, it must even be within the area code’s zone: a 02 number requires an address in the Brussels region. For a mobile, an address anywhere in Belgium is enough.
The central document is the extract from the Crossroads Bank for Enterprises (CBE, BCE in French, KBO in Dutch), Belgium’s official business register. It proves the company exists, gives its company number and can serve as proof of address.
