Regular Expressions for Validation

Use the following regular expressions to validate Burundi phone numbers in your applications:

  • General Format: ^\+257\d{8,9}$
  • Landline Numbers: ^22\d{7}$
  • Mobile Numbers: ^(79|71)\d{7}$
  • Toll-Free Numbers: ^800\d{6}$
  • Premium Services: ^90\d{7}$

Dialing Procedures

Domestic Calls

  • Landline to Landline: Dial the 9-digit number directly (e.g., 223456789).
  • Landline to Mobile: Dial the 9-digit mobile number directly (e.g., 791234567).
  • Mobile to Mobile: Dial the 9-digit mobile number directly (e.g., 791234567).

International Calls

  • Outgoing: Dial 00 (international prefix), followed by the country code, and then the subscriber number (e.g., 00 1 2025550123 for a call to the USA).
  • Incoming: Callers from abroad should dial +257 followed by the 9-digit local number (e.g., +257791234567).

Number Portability

As of the latest available data, Burundi does not support mobile number portability (MNP). This means that subscribers cannot retain their phone numbers when switching between mobile service providers.

Telecom Operators and Number Ranges

Burundi has several telecom operators, each assigned specific number ranges:

Recent or Upcoming Changes

There have been no recent changes to the numbering plan in Burundi as of the latest updates. Any future changes will be announced by the Agence de R??gulation et de Contr??le des T??l??communications (ARCT).

Number Allocation and Management

The Agence de R??gulation et de Contr??le des T??l??communications (ARCT) is responsible for the allocation and management of phone numbers in Burundi. They ensure compliance with ITU-T standards and manage the numbering resources efficiently.

Technical Restrictions and Special Cases

  • Golden Numbers: These are special numbers that may have a memorable sequence and are often sold at a premium.
  • Number Blocking: Certain number ranges may be blocked or reserved for special purposes, such as government use or emergency services.

Technical Considerations for Developers

When designing systems that handle Burundi phone numbers, consider the following:

  • Validation: Use the provided regular expressions to ensure that phone numbers are correctly formatted.
  • Internationalization: Always store phone numbers in the E.164 format to facilitate international calling and interoperability.
  • Error Handling: Implement robust error handling for scenarios where a user inputs an invalid or incomplete phone number.
  • Timezone Awareness: Burundi operates on Central Africa Time (CAT), UTC+2. Ensure your systems account for this when scheduling calls or sending time-sensitive messages.
