The Authority for Info-communications Technology Industry of Brunei Darussalam (AITI) is responsible for managing numbering under the AITI Order 2001.

The National Numbering Plan sets out the guidelines for management of Numbering resources.

Number Categories

In Brunei Darussalam, there are three Number categories:-

Geographic Numbers

Geographic numbers are numbers that consist of digits that indicate the geographical location of the Number. The uses of Geographic Numbers are presently limited to fixed telephony and data services.

Non-Geographic Numbers

Non-geographic numbers are numbers that consist of digits that have no relation to the geographic location of the service provided by the number. There are different categories of Non-Geographic Numbers:

  • Short Codes – (3 and 5 digit numbers)
  • Special Number – (5 digit, 1800, 1900, 800, 801 and IP telephony)
  • Mobile Number

For detailed description of each Number category please download National Numbering Plan.
