SIP Trunk Belgium — +32 Termination & DID Numbers
Belgium has three official languages, so a single Brussels support line often needs Dutch, French and German IVR branches behind it. Mobile numbers start with 04 and fixed lines use short area codes such as 02 for Brussels and 03 for Antwerp.
Overview
Routing calls to Belgium
Calling windows matter: Belgium runs on Brussels time, and we route +32 calls for Brussels, Antwerp and Ghent, Liège and Bruges across several carriers so a peak-hour congestion event on one network does not take your campaign down.
Numbering in Belgium is managed by BIPT. We terminate to geographic, national, mobile and toll-free ranges and price each one separately on the rate sheet. Inside the country, numbers are dialled with a 0 trunk prefix. Strip it before you send the call, and send 32 followed by the national number.
For inbound numbers in Belgium, plan on paperwork: proof of address and company or identity documents are usually required before a DID goes live. Termination needs no documents beyond normal account checks.
