Area Code 24 – Brunei Muara

Overview of Brunei +673 24

The country calling code +673 is assigned to Brunei Darussalam under the ITU-T E.164 international numbering plan. Within the national numbering plan, the prefix 24 is a geographic area code that designates the Brunei Muara District, the most populous and economically significant district in the country. This district is home to the capital city, Bandar Seri Begawan, and serves as the administrative, commercial, and financial hub of Brunei.

Geographic Coverage and Major Localities

The 24 area code covers the Brunei Muara District, which includes not only the capital but also several key suburbs and towns such as Berakas, Gadong, Kiulap, and Sengkurong. Gadong is particularly known for its commercial centers and shopping complexes, while Kiulap is a popular dining and business area. The district also hosts Brunei International Airport, making this code relevant for businesses and services located near the airport.

Dialing Format and Instructions

When dialing a Brunei Muara landline from within Brunei, you must include the trunk prefix 0 before the area code and subscriber number. The national significant number (NSN) for a fixed-line in Brunei is 7 digits, consisting of the area code (without the leading 0) and a 5-digit subscriber number. For example, a local number might be formatted as:

• Local dialing (within Brunei): 0 24 X XXXX
• International dialing (from abroad): +673 24 X XXXX

For instance, if the subscriber number is 12345, you would dial 02412345 from a Brunei mobile or another fixed line, and +673 24 12345 from outside the country. Note that the leading '0' is not used when dialing from abroad; the +673 country code replaces it.

Overlay and Numbering Considerations

Brunei's numbering plan does not currently employ overlay codes for geographic areas; each district retains its own unique area code. The Brunei Muara district uses 24, while other districts have different codes (e.g., 3 for Belait, 4 for Tutong, and 5 for Temburong). This simplifies dialing but requires callers to know the correct area code for the destination.

Caller Instructions

For local callers within Brunei, always include the trunk prefix 0 when dialing a fixed-line number in another district. For international callers, ensure you have the correct country code (+673) and drop the leading 0. It is also advisable to check with your telecom provider for any special international dialing prefixes that may be required in your country.
