Geographic Overview of Brunei Area Code 50
In Brunei Darussalam, the telephone numbering plan follows the ITU-T E.164 standard, with country calling code +673. Area code 50 is designated for the Temburong District, the country's eastern exclave separated from the main Brunei-Muara, Tutong, and Belait districts by the Brunei Bay and the Malaysian state of Sarawak. Temburong is the least populous district, known for its pristine rainforests and the Ulu Temburong National Park. The district's administrative center is Bangar, the primary town served by this code.
Dialing Formats and Usage
Within Brunei, calls to Temburong numbers require dialing the full eight-digit subscriber number, which includes the area code. For example, a local call to a landline in Bangar would be dialed as 50XXXXXX (where XXXXXX is the six-digit local line). Internationally, callers must dial +673 50XXXXXX or 011 673 50XXXXXX from North America, omitting any leading trunk prefix. There is no separate trunk prefix like '0' used in Brunei; the country code +673 is always followed by the eight-digit national number.
Geographic Coverage and Administrative Jurisdiction
Area code 50 covers the entire Temburong District, including Bangar and smaller settlements such as Labu Estate, Batu Apoi, and Amo. The code is allocated to fixed-line services, primarily provided by the national telecommunications operator, UNN (Unified National Networks). As with other geographic codes in Brunei, the prefix is tied to the physical location of the telephone exchange, and numbers are not portable outside the district.
Caller Instructions
For local callers within Brunei: simply dial the eight-digit number starting with 50. For international callers: dial your country's exit code (e.g., 00, 011), then Brunei's country code 673, followed by the eight-digit number. Do not add any extra digits. For example, to call a Temburong number from the UK, you would dial 00 673 50XXXXXX. From the US, it would be 011 673 50XXXXXX.
As of the current numbering plan, there are no overlay codes in Brunei; each geographic area has a unique code. However, with the increasing adoption of VoIP and mobile services, it is always advisable to confirm the number's validity and current format with your service provider.
