About Brunei Calling Code
To reach Brunei from another country, first dial the international calling code +673 — assigned by the ITU — followed by the local number. Brunei is located in Asia, in South-Eastern Asia.
Brunei is known locally as Negara Brunei Darussalam — Bandar Seri Begawan is the capital. When saving an international contact, write the number in full international format with +673 so it works from any country.
International calling codes follow the ITU-T standards E.123 and E.164, which define how phone numbers are written and dialed across borders. The prefix you dial after the exit code tells the global telephone network which national network to route the call to.
Where the +673 Calling Code Is Used
The country code +673 is assigned to Brunei, located in South-Eastern Asia, with the capital Bandar Seri Begawan. This code is part of the international telephony numbering plan and is used for all calls made to Brunei from outside the country.
When a number is written as +673 …, the +673 prefix directs your call to the Brunei national network. After the prefix, dial the area code without its leading zero, then the subscriber number — the same pattern for landlines and mobiles.
ITU-T E.164 groups calling codes by world region; codes beginning with 6 cover the part of the world that includes Brunei, in South-Eastern Asia. Storing numbers with +673 and omitting the domestic leading zero keeps contacts dialable from anywhere.
Brunei Phone Number Formats
The ITU E.164 format for Brunei numbers is +673 + area code + subscriber number, used for landlines and mobiles alike. Here is the general structure:
📱 Number Structure
- International format: +673 [area code] [subscriber number]
- From abroad: exit code + +673 + local number (drop the trunk prefix 0)
- Within Brunei: dial the local number directly
Numbering plans vary: closed plans use fixed-length national numbers, while open plans allow variable lengths with a trunk prefix (usually 0) that is dropped for international calls. For calls to Brunei, replace the trunk zero with +673.
Time Zone in Brunei
The local time in Brunei follows the Asia/Brunei time zone (UTC+08:00 UTC). Check the time difference before you dial so your call arrives during waking hours.
Time differences matter when calling Brunei: if it is UTC+08:00 there, a morning call from Europe may reach Bandar Seri Begawan in the afternoon, while callers in the Americas should check the offset to avoid late-night calls.
If Brunei observes daylight saving time, its UTC offset shifts by an hour twice a year. Double-check the current offset before time-sensitive calls, especially in spring and autumn.

Example: Calling Brunei Numbers in Practice
Here is how a typical call to Brunei works, depending on where you are calling from:
🌍 From the United States or Canada
- Dial the US/Canada exit code 011
- Dial the Brunei country code +673
- Dial the local number (area code + subscriber number, without the trunk prefix 0)
Example: 011 +673 [area code] [number]
🌍 From the United Kingdom or Europe
- Dial the international access code 00 (or use the + symbol on mobile)

If the local number begins with a trunk prefix (commonly 0), remove it when dialing internationally — +673 takes its place. The remaining digits are dialed exactly as written.
