Area Code 224 – Brunei Muara

Overview of Brunei Area Code 224

Area code 224 is a geographic National Destination Code (NDC) assigned to the Brunei Muara District, the smallest but most populous district in Brunei Darussalam. This district hosts the national capital, Bandar Seri Begawan, along with key administrative, commercial, and residential zones. The code is part of Brunei's national numbering plan under the ITU-T E.164 standard, which uses the country calling code +673.

Geographic Coverage and Administrative Jurisdiction

The 224 prefix serves fixed-line subscribers within the Brunei Muara District, including areas such as Kianggeh, Berakas, Gadong, and Jerudong. It covers government offices, businesses, and residential landlines in the capital region. As a geographic code, it is tied to the physical location of the subscriber's line, and calls are routed via the PSTN (Public Switched Telephone Network) to the corresponding exchange.

Dialing Formats and Caller Instructions

Brunei uses a closed dialing plan for domestic calls. When calling a number within Brunei Muara from another district, you must dial the full national number, which includes the area code and the subscriber number. The area code is always dialed, even for local calls within the same district.

• Local call (within Brunei): Dial 224 XXXX (where XXXX is the 4-digit subscriber number). Example: 224 5678.
• International call from abroad: Dial your country's international exit code (e.g., 00 from many countries, 011 from the US/Canada), then 673 (Brunei's country code), then 224 and the subscriber number. Example: +673 224 5678.

Note: When calling from a mobile phone, you can use the plus sign (+) instead of the exit code. Ensure you omit any leading trunk prefix (Brunei does not use a trunk prefix like '0' for domestic calls).

Overlay Considerations and Numbering

Currently, there are no overlay codes for Brunei Muara; the 224 code remains the sole geographic code for the district. Subscriber numbers are typically 4 digits, making the total national number length 7 digits (excluding the country code). This structure is consistent across Brunei's fixed-line network.

Practical Tips for Callers

For international callers, always verify the correct number of digits. A typical Brunei fixed-line number in the 224 area will have the format 224-XXXX. If you are unsure about a number, contact the local directory assistance. For businesses, ensure your contact details are published with the full international format to facilitate global communication.
