Belgium phone number format
How do you format a Belgium phone number?
Write a Belgium phone number with the country code +32. A mobile looks like 0450 00 12 34 inside Belgium and +32 450 00 12 34 from abroad, dropping the leading 0. Mobiles have 9 digits after the country code, and the E.164 form is +32450001234. Format alone never shows a line is in service.
Free, runs in your browser; nothing is sent. The sample is a sample, not a real line.
Paste your Belgium numbers (a mixed list is fine). They are counted here at once; the free checker then gives every number its E.164 form, country and line type, with a file to download.

These are the example numbers from Google’s libphonenumber data, the same numbering-plan data our validator uses, written three ways.
| Format | Mobile | Landline |
|---|---|---|
| National (inside Belgium) | 0450 00 12 34 | 012 34 56 78 |
| International | +32 450 00 12 34 | +32 12 34 56 78 |
| E.164 | +32450001234 | +3212345678 |
How to write a Belgium number in E.164
- Remove spaces, dashes, dots and brackets so only digits are left.
- If the number starts with the trunk prefix 0, remove it. It is only used when dialling inside Belgium.
- Put +32 in front. The result has 9 digits after the country code for a mobile.
So 0450 00 12 34 becomes +32450001234. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.
Mobile or landline?
Belgium allocates separate number ranges to mobiles and landlines, so a numbering-plan check reads the line type straight from the digits, for free. That type describes the range the number came from. It doesn’t prove the number is connected today.
Mobile, landline and special number ranges in Belgium
A Belgium mobile number starts with 45–49 after +32. Every valid number of each type below starts with one of the digit groups shown. A number that starts the right way can still be unassigned: the groups say what a range is for, not that a number is connected.
| Type | Starts with, after +32 | Dialled inside Belgium | Digits | Example |
|---|---|---|---|---|
| Mobile | 45–49 | 045–049 | 9 | +32 450 00 12 34 |
| Landline (fixed line) | 1–9 | 01–09 | 8 | +32 12 34 56 78 |
| Toll-free | 8001–8009 | 08001–08009 | 8 | +32 800 12 345 |

Common questions
- What is the country code for Belgium?
- The country calling code for Belgium is +32. When you call Belgium from abroad, dial your international prefix (or +) followed by 32 and the number without its leading 0.
- How many digits is a Belgium phone number?
- A Belgium mobile number has 9 digits after the country code +32, and a landline has 8. Written for dialling inside Belgium, a number gains the trunk prefix 0 in front.
- How do I write a Belgium number in international format?
- Start with +32, drop the leading 0, then add the rest of the number. The mobile number 0450 00 12 34 becomes +32 450 00 12 34, or +32450001234 in E.164, the form most CRMs and SMS tools expect.
- Can you tell if a Belgium number is a mobile?
- Usually, yes. Belgium numbers come from ranges allocated separately to mobiles and landlines, so a numbering-plan check reads the line type from the digits. It tells you what the range is for, not whether the number is in service.
- Does a valid format mean a Belgium number is in service?
- No. A valid format means the digits fit a range Belgium's numbering plan allocates. It cannot tell whether the number is connected today or who carries it, because numbers are reassigned and ported. A live carrier lookup reports the current carrier and line type, but even that does not prove someone answers.
