Burundi phone number format

How do you format a Burundi phone number?

Write a Burundi phone number with the country code +257. A mobile looks like 79 56 12 34 inside Burundi and +257 79 56 12 34 from abroad. Mobiles have 8 digits after the country code, and the E.164 form is +25779561234. A format check confirms the digits fit the numbering plan, not that the number is in service.

Example Burundi phone numbers

These are the example numbers from Google’s libphonenumber data, the same numbering-plan data our validator uses, written three ways.

How to write a Burundi number in E.164

1. Remove spaces, dashes, dots and brackets so only digits are left.
2. Burundi has no trunk prefix, so keep every digit of the national number.
3. Put +257 in front. The result has 8 digits after the country code for a mobile.

So 79 56 12 34 becomes +25779561234. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.

Mobile or landline?

Burundi 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 Burundi

A Burundi mobile number starts with 29, 61–69, 71, 72, 75–79 after +257. 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.

Usually, yes. Burundi 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 Burundi number is in service?

No. A valid format means the digits fit a range Burundi's numbering plan allocates. It cannot tell whether the number is connected today or who carries it, because numbers are reassigned and ported.
