Cyprus adopted a closed telephone numbering plan on 1 December 2001. As a result, for land line phone numbers the digit 2 followed by the old area code was affixed to the subscriber number and for mobile phones 9 was affixed to the phone number. The plan is also used in Akrotiri and Dhekelia. Previously, landline numbers consisted of the trunk code 0, the area code, and a six-digit number. Under the new system, these changed to numbers with eight digits, to be dialled from within Cyprus or abroad. Mobile phone numbers had the prefix 09, followed by six digits, which had to be dialled in full.
