The numbering plan of Burundi: formats, lengths, the regular expression for each line type and the prefix blocks allocated to each carrier, as ITU publishes it. A pattern says what a number looks like and where it was allocated; whether it is in service, and who serves it today, is a different question (below).

Test a pattern
Tick the line types you accept, copy the combined pattern, and paste numbers to see which range each one falls in. Numbers are reduced to their national digits first (no spaces, no +257, no trunk prefix); nothing leaves your browser.
^(?:(?:29|6[1-9]|7[125-9])\d{6}|(?:22|31)\d{6})$| Number | National digits | Matches |

Walk the prefixes
Type the first digits of a number in national form, or tap them: the operators holding blocks under those digits, then the block a full prefix falls in. 9 blocks held by 4 operators are on record.

Line types and their regular expressions
Match each pattern against the national significant number: digits only, without the trunk prefix and without +257. The patterns follow the national numbering plan and are anchored here.

|---|---|---|---|
| Mobile | 8 | 79 56 12 34 | +25779561234 |
| Fixed line | 8 | 22 20 12 34 | +25722201234 |

Questions developers ask
- How many digits does a phone number in Burundi have?
- Mobile numbers have 8 national digits. Fixed line numbers have 8 national digits. That is the national number, without the country code +257.
- What is the country code for Burundi?
- +257. From abroad, dial your own exit code, then 257, then the national number. From inside Burundi, the exit code for international calls is 00.
- Which prefixes are mobile numbers in Burundi?
- Mobile numbers start with 2, 6 or 7 in national form; the mobile regular expression on this page gives the exact ranges (example: 79 56 12 34). The carrier table shows which prefix blocks were allocated to which operator.
- Can a mobile number in Burundi be ported to another carrier?
- Not on record. The plan data this page is built from does not list mobile number portability for Burundi, so the carrier a prefix was allocated to is likely, not certainly, the carrier serving the number. Only a live carrier lookup (an HLR or MNP query) confirms it.
