This code was introduced on 1 July 1998 when Chad switched from its old international dialling code of +800 to +235 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 Chad from abroad. Check programingplease for Chad in 2010.
