Numbering range information

20 March 2008 - expansion to 8-digit national numbering

In 2009, national numbering expands to 8-digit format, where digit '2' was prepended to existing fixed/wireline numbers, while digit '8' was prepended to mobile numbers (not '3' as previously reported here). Permissive use of 7-digit numbers was in effect until 20 September 2008 after which the 8-digit numbers became mandatory.
