How do I dial mobiles vs landlines in Brunei

Brunei’s country calling code is +673 and the national numbers are 7 digits. From abroad, dial your exit code → 673 → the 7-digit number (there’s no trunk “0”—it was removed in 2003). From inside Brunei, just dial the seven digits; international calls use the 00 exit prefix. Typical formats: landline +673 2xx xxxx / 3xx xxxx / 4xx xxxx / 5xx xxxx, mobile +673 7xx xxxx / 8xx xxxx.

Mobiles vs landlines: Brunei has no geographic area codes today; use +673 + 7 digits everywhere. (Historically, 0x area codes existed but were withdrawn). Fixed lines generally start 2/3/4/5, while mobiles start 7 or 8 (and, since 2014, 228/229 were reallocated from fixed to mobile). Brunei supports number portability across mobile (and fixed) services, so the first digits show the original allocation—not always the current operator.

What are the city and area codes in Brunei

Dialing tip: Converting a local number to international is easy—just add +673 in front. There’s no “0” to drop.

City	Area Code	International Dialing Format
Bandar Seri Begawan (Brunei-Muara)	typical fixed 2xx/3xx	+673 2xx xxxx / +673 3xx xxxx
Kuala Belait & Seria (Belait)	typical fixed 3xx	+673 3xx xxxx
Tutong (Tutong District)	typical fixed 4xx	+673 4xx xxxx
Bangar (Temburong District)	typical fixed 5xx	+673 5xx xxxx

Which mobile prefixes do mobile operators use in Brunei

Dialing tip: Because MNP is available, don’t assume 7 = Progresif or 8 = DST today—dial the full number exactly as written. For any older +673 228/229 xxxx numbers, note that these are now mobile ranges per the national plan update.

Mobile Operator	Dialing Prefixes
DST (Datastream Digital)	commonly 8xx xxxx ranges
Progresif	commonly 7xx xxxx ranges
imagine	retail provider on the UNN wholesale network; participates in Brunei’s number portability program.
