Telephone numbers in Turkey

Telephone numbers in Turkey went from six to seven digits circa 1988. There used to be more than 5,000 local area codes of varying lengths with correspondingly varying local number lengths.
The new system imposes three-digit area codes for provinces and seven digit local phone numbers. Istanbul is the only exception, having two different area codes.
The prefixes for the three major Turkish operators are as follows: Turkcell, Vodafone Turkey, and Türk Telekom.
On 30 August 1993, local numbers in most areas were changed in conjunction with a new numbering plan.
