Brunei at a glance
The numbers and facts you need before you dial.
What is the country code for Brunei?
Brunei's numbering plan is unusually split: landline numbers are 7 digits, while mobile numbers are also 7 digits — but the two share the +673 code with no area codes and no trunk prefix, making the opening digits the only way to tell them apart.
The country's telecom landscape is equally distinctive. Brunei has three operators serving a population of roughly 450,000, giving it one of the highest operator-per-capita ratios in Southeast Asia. The dominant carrier, DST (Data Stream Technology), is a subsidiary of Brunei's sovereign wealth fund and has been the country's telecom backbone since mobile services launched in the 1990s. Progresif Cellular, which entered in 2014 as the nation's first true mobile competitor, reshaped the market almost overnight by offering aggressive data packages that forced DST to modernize its pricing. Imagine rounds out the trio as the fixed broadband and enterprise provider.
All three operate under the regulatory authority of AITI (Authority for Info-Communications Technology Industry), Brunei's telecom regulator — and all three share the single +673 code with no geographic area codes, a simplicity that reflects the country's compact geography: the entire nation is smaller than the U.S. state of Delaware.
Code +673 was assigned to Brunei by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to Brunei.
How to call Brunei from anywhere
The pattern: your exit code + 673 + the 7-digit local number. No area code, no trunk zero. On any mobile, press and hold 0 until it becomes + — the + replaces the exit code automatically.
Full example: +673 222 1234 — Brunei has no trunk prefix; dial the country code plus the 7-digit number exactly as shown.
Brunei phone number format explained
All Brunei numbers are 7 digits after the +673 country code — 10 digits in total internationally. The opening digits identify the type: landline numbers start with 2, 3, 4 or 5, with 2 (Bandar Seri Begawan and surrounding districts) the most common. Example: +673 222 1234.
Mobile numbers start with 7 or 8. DST mobiles typically begin with 71x, 72x, 81x or 82x. Progresif mobiles use 73x and 83x. Example: +673 712 3456.
There is no trunk prefix. When dialing within Brunei, you dial the 7-digit number directly — no leading 0.
Landline
+673 2xx XXXX (Bandar Seri Begawan) / +673 3xx, 4xx, 5xx XXXX (other districts)
Mobile
+673 71x/72x/81x/82x XXXX (DST) · +673 73x/83x XXXX (Progresif)
Brunei area codes — major cities
Drop the local leading 0 when calling from abroad.
| City | Region | Area code |

| Bandar Seri Begawan | Capital and surrounding districts — most common landline prefix (2xx) | 222 |
| Other districts | Regional landline exchanges | 3xx / 4xx / 5xx |
Brunei mobile network prefixes
The prefix after +673 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
DST (Data Stream Technology)
Incumbent and largest mobile operator; 2G/3G/4G LTE and 5G, ultimately owned by Brunei's sovereign wealth fund.
Progresif Cellular
Entered in 2014 as Brunei's first true mobile competitor; aggressive data plans and 4G LTE coverage.
Imagine (formerly B-Mobile)
Fixed broadband, IPTV & enterprise connectivity provider — smaller mobile presence, no dedicated consumer mobile-prefix block.
Brunei time zone
Brunei operates on Brunei Darussalam Time (BNT), UTC+8, year-round with no daylight saving. This puts it in the same time zone as Singapore, Malaysia, Hong Kong and Perth.
For business calls, aim for 9 AM – 12 PM BNT. Government and corporate offices typically operate 7:45 AM – 12:15 PM and 1:30 PM – 4:30 PM, with a break for prayers. Friday is a half-day in government, and Brunei observes Friday and Sunday as the weekend — Saturday is a working day in most government offices, though private-sector companies often follow a Monday-to-Friday schedule.
Emergency numbers in Brunei
Free to call from any Brunei phone, landline or mobile.
Common mistakes when calling Brunei
Almost every failed international call is a formatting issue, not a network issue.
Adding a trunk 0 after the country code
Brunei has no trunk prefix. Dial +673 plus the 7-digit number directly. Never insert a 0 between the country code and the number.
Confusing +673 with +63 (Philippines)
The codes differ by a single digit. +673 is Brunei; +63 is the Philippines. Double-check before dialing.
Dialing 8 digits instead of 7
Brunei numbers are exactly 7 digits after +673. If a number looks longer, it may include a formatting space or an old prefix that's no longer valid.
Calling during Friday morning
Friday is the Islamic holy day. Government offices close early or are closed entirely; many businesses pause for congregational prayers. Schedule calls for Saturday through Thursday.
Assuming Malaysian +60 works
Brunei is geographically surrounded by Malaysia but has its own +673 code. A Malaysian +60 number will not reach Brunei.
Tips to reduce the cost of calling Brunei
Route calls over VoIP instead of paying per-minute international rates
International rates to Brunei from the US or UK typically run $0.10–$0.30/min via major carriers. Apps like WhatsApp, Skype, and Zoom route over the internet and bypass those charges — Brunei's broadband penetration is high, so voice quality is usually good.
Get a local +673 number for a genuine Brunei presence
A virtual +673 number from MCM gives businesses a local Brunei caller ID and routes inbound calls at domestic rates, regardless of where the team sits.
Schedule around Brunei's Friday–Sunday weekend
Government offices close early on Friday for prayers and are closed on Sunday — plan calls for Saturday through Thursday to reach decision-makers reliably.
Use the opening digit as a quick number-type check
Landline numbers start with 2–5, mobile numbers start with 7–8 — a fast way to tell what kind of number you're dialing before you call.
Why businesses get a Brunei virtual number
Brunei's economy revolves around oil and gas — the country is Southeast Asia's fourth-largest oil producer and the ninth-largest LNG exporter globally. But beyond hydrocarbons, the sultanate is actively diversifying into halal manufacturing, Islamic finance and tech under its Wawasan 2035 vision. Companies servicing the energy sector, Islamic banking institutions, halal supply-chain firms and tech vendors doing business in Brunei all benefit from a local +673 presence.
