199x - Transition from 6-digit to 7-digit numbers

2000 - Transition from 7-digit to 8-digit numbers

On 2000-10-13 at 23:00 UTC, the numbering area in Morocco was split into 5 parts by adding another digit to all area codes in Morocco.

2006 - Merger of 04 into 02 and 05 into 03

Six years later (2006-03-24 23:00 UTC), part of this split was reverted in order to make room for cellular networks. The 04 numbering area was merged into 02 and 05 was merged into 03, which caused 02 to cover the South while 03 covered the North. This could be done easily because there were no conflicts.

2009 - Transition from 8-digit to 9-digit numbers

On 2009-03-07 at 02:00 UTC, phone numbers in Morocco got another additional digit. A 5 was prepended to all fixed numbers while a 6 was prepended to mobile numbers. The 08 numbers became 080 and 09 became 089.
