Belgium's country code is +32. From the UK, dial +32 then the Belgian number with the domestic leading 0 dropped. A Brussels landline printed as 02 XXX XX XX is +32 2 XXX XX XX. A Belgian mobile printed as 04XX XXXXXX is +32 4XX XXXXXX. Do not keep the 0 after +32: +32 02 is a misdial.
How to dial
Use one of these origin formats:
- ›+32 plus the national significant number (usual on a mobile)
- ›00 32 plus the same digits from a UK landline that still needs the international access prefix
Ofcom's National Telephone Numbering Plan designates 00 as access to international telephone numbers from the UK. + is a substitute on many mobiles. Do not assume every device accepts the same input.
More numbers: call Belgium. Area codes: Belgium calling codes.
The ITU E.164 list assigns 32 to Belgium. Brussels geographic numbers use 2 (printed 02). Antwerp uses 3 (printed 03). Belgian mobiles use 4 after +32 (printed 04xx). A prefix is a format hint, not proof of the current network.
Cost
A call from the UK to Belgium is an international call from home. That is not the same as roaming while you are in Belgium.
EE's call-abroad page sells International Pass and International Extra add-ons for calls from the UK, plus separate EU / rest-of-world minute add-ons on pay as you go. Inclusive minutes, if any, are plan-specific. Check whether Belgium is named on the destination list.

If Belgium is already in your UK calling allowance, use your handset. If it is not, you can place the call in the browser. How calling works: how it works.
When 0800 is the wrong number
Belgian 0800 is a domestic freephone range. BIPT describes 0800 as free for the caller on Belgian fixed and mobile networks, with the called party paying. Do not assume a domestic toll-free number will work from the UK. Use the number the organisation publishes for international callers.
SPF Finances contacts for overseas callers are on SPF Finances from abroad.
Time difference
Belgium is one hour ahead of the UK throughout the year. Both countries change their clocks on the same schedule. Check the organisation's local opening hours before calling.
Format mistakes to avoid
- ›Keeping 02 after +32 (Brussels must be +32 2)
- ›Assuming an 0800 number will work from the UK
- ›Confusing roaming in Belgium with an international call placed from the UK
