Brunei numbering plan & how to dial
Under country code +673, Brunei runs a closed numbering plan — just a 7-digit subscriber number after the country code, no area code required.
With 95% internet penetration, Brunei is covered by 2 major carriers — DST Communications, Progresif. VoIP is permitted and regulated by Authority for Info-Communications Technology Industry (AITI). IVR prompts, SMS copy, and business hours here should account for the local language (Malay) and currency (BND).
Asian markets range from fully liberalised to licensed-only VoIP, so compliant routing and correct local caller ID have an outsized effect on answer rates.
Skipping the exit code
From the US you must dial 011 before the +673 country code to reach Brunei.
Adding an area code that doesn't exist
Don't insert an area code for Brunei: it's a closed plan, so +673 plus the 7-digit number is the whole address.
Ignoring the time difference
Before dialing Brunei, check the local clock — it runs on UTC+8, and off-hours calls tend to go unanswered.

The US exit code is 011 for any international call, including to Brunei. It comes right before the +673 country code, and Twiching adds both automatically when you dial from the app, so you only need to enter the local number.
