The area code of Brunei is +673. This code was introduced on 1 January 1966 when Brunei switched from its old international dialling code of +800 to +673 for all incoming calls from abroad. This change was made so that all incoming calls would be routed through international carriers instead of neighbouring countries. This has helped increase security as well as improve call quality for customers calling into Brunei from abroad. Check programingplease for Brunei in 2010.
