Brunei Darussalam - Personal names and forms of address


Normal forms of address are:

   Males            Awang
   Females          Dayang

Certain distinguished males used the form of address Awangku which becomes Pengiran (Pg.) upon marriage. This is a hereditary title. It is a grave faux pas to address these people as Awang. The wife of a person with the form of address Pengiran also takes the form of address Pengiran.

The titles Dato (male) / Datin (female) and Pehin (male) may be bestowed by the Sultan. People with both awards may be addressed Pehin Dato ….

Naming conventions follow the Muslim norms, and usually contain no family names. Brunei women retain their names upon marriage.

Brunei names may contain Arabic elements such as bin (“son of”) and binti (“daughter of”). Haji (male) and Hajah (female) may be added to names of those who have been on a pilgrimage to Mecca. This is written twice if one’s father has been to Mecca, and may be abbreviated to Hj in this way:

   Hj Morshidi bin Hj Mohamed Yussof

meaning Morshidi (who has been to Mecca), son of Mohamed (who has been to Mecca) Yussof. This person would then be addressed as:

   Awang Haji Moshidi 

For the Chinese community, names are formatted in the Chinese fashion – please refer to the chapter on China for further details.

Brunei Darussalam - Postal codes


Brunei has altered its postal code (known locally as Postcode) pattern in 1999 to include two letters before a block of 4 digits in this pattern:


The first letter indicates the province (daerah), the second the county (mukim). The first two digits of the number indicate the district or village (kampong/kawasan), and the final two digits indicate the post office/route (pejabat penerahan). The system includes separate codes for large-users.

The relationship between the code BS (for Bandar Seri Begawan) and those codes of the mukims it occupies is unclear.

The first letters can be BA to BU (excluding BI, BO and BQ); KA to KH, PA to PE or TA to TH.
