Connect Worldwide with a Belgian International Number

A Belgian international number is a virtual phone line that uses the +32 dialing code and functions just like a local Belgian number — even if you’re based in the UK or abroad. Customers or contacts in Belgium will see a local number when calling or receiving calls, improving trust and accessibility.

Once active, you can forward calls to your landline, mobile, or VoIP system anywhere in the world.

Belgium uses toll-free numbers starting with 0800. For international customers, UIFN numbers like 00800 are available.

Common formats include:

• 0800 XXX XX – Toll-free within Belgium.
• 00800 XXX XXXX – Global UIFN format.

These numbers are free for the caller and ideal for customer service lines or international businesses serving Belgian customers.

Belgian phone numbers follow a structured format that makes them easy to identify and dial. The total length is always 10 digits when including the initial “0” for domestic calls, or 9 digits after the +32 country code for international calls.

Geographic numbers are organised by region, with major cities like Brussels and Antwerp having shorter area codes (02, 03) due to their size and importance, while smaller regions may have longer prefixes. Mobile numbers are distinguished by starting with 04x prefixes, making it simple to identify whether you’re calling a landline or mobile phone at a glance.

Here are the key regions and their dialing code prefixes:

Key Notes:

• Mobile numbers begin with 04x, e.g. 047, 048.
• When dialling internationally, replace the “0” with +32.
• Example: 0470 12 34 56 → +32 470 12 34 56.
