Telephone numbers in Turkey went from six (2+4) to seven digits (3+4) circa 1988.

The new system imposes three-digit area codes for provinces and seven digit local phone numbers.

Access to automatic telephone service within Turkey: trunk / inner - city code number: 0 Access to international telephone service from Turkey: international code: 00 Note: Subscribers' numbers cannot be prefaced with the number 1.

Ankara DMS-300 Istanbul DMS-300 İzmir DMS-300 Ankara, İstanbul and İzmir DMS-300 International Exchanges accept: L/D + area code + subscriber number + ST L/D = language digit: 0 (direct dialing) L/D = language digit: 2 (operator assistance) There are two international operator centers in Turkey, Ankara and İstanbul.

Note: These are the codes that wireless operators in Turkey assign to new subscribers.
