This code was introduced on 15 April 2002 when Afghanistan switched from its old international dialling code of +873 to +93 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 Afghanistan from abroad. Check programingplease for Afghanistan in 2010.
