Overview
The area code 227 is a geographic National Destination Code (NDC) assigned to the Brunei Muara District, the smallest but most populous district in Brunei, which includes the capital city, Bandar Seri Begawan. This code is part of Brunei's national numbering plan under the ITU-T E.164 recommendation, and it is used for fixed-line telephone services within the district.
Geographic Coverage
Brunei Muara District is the administrative and economic heart of Brunei, encompassing the capital and its surrounding urban and suburban areas. The 227 prefix serves both residential and business fixed-line subscribers in this region. Key locations covered by this code include:

Dialing Formats
Brunei uses a closed numbering plan, meaning the national significant number (NSN) is always 7 digits, and the area code is part of the subscriber number. For local calls within Brunei Muara (and across Brunei), you must dial the full 7-digit number, including the area code. The international format includes Brunei's country calling code +673.
- Local dialing (within Brunei): Dial 227XXXX (7 digits total).
- International dialing (from abroad): Dial your country's exit code, then +673 227XXXX (no trunk prefix is used).
For example, to call a fixed line in Bandar Seri Begawan with the number 2271234:
- From within Brunei: 2271234
- From the United States or Canada: 011 673 2271234
- From the United Kingdom: 00 673 2271234
Caller Instructions
If you are calling from outside Brunei, always replace the leading '0' (if any) with the country code +673. Brunei does not use trunk prefixes like '0' for domestic calls; the number is dialed as is. For international callers, ensure you have the correct exit code for your country before dialing +673.
Overlay and Numbering Considerations
Brunei's numbering plan is administered by the Authority for Info-communications Technology Industry of Brunei Darussalam (AITI). Currently, there are no overlay codes in Brunei; each geographic area has a distinct NDC. The 227 code is dedicated to Brunei Muara, while other districts have their own codes (e.g., 222 for Belait, 223 for Tutong, 224 for Temburong). This structure ensures that callers can easily identify the geographic origin of a fixed-line number.
As Brunei continues to modernize its telecommunications infrastructure, fixed-line numbers remain important for businesses and government offices, though mobile penetration is high. The 227 code is expected to remain stable for the foreseeable future, but users should always verify the latest numbering plan updates from AITI.
