Turkey went from six (2+4) to seven digits (3+4) local phone numbers c.1988, at which time Ankara went from 41 to 4. There used to be more than 5000 local area codes of varying lengths (one to five digits) with correspondingly varying local number lengths (seven to three digits). The new system is based on 83 three-digit area codes for provinces and seven digit local phone numbers. Istanbul is the exception and it gets two area codes ((212) for the European and (216) for the Asian side). Calling a cell phone from outside Turkey is the same except the three digit numbers are replaced with the ones of the companies. Like () + () + (company id number ) + (digit number ). The following are the company identification numbers for the major mobile telephone providers: Turkcell (530-539), Vodafone (540-549) and Avea (500-509 and 550-559). Local numbers in most areas were also changed in conjunction with the numbering plan that took effect 1 August 1993. If a former area code is indicated, this is for the major centre in the new area code's district. The new area codes will also replace former area codes other than the primary one mentioned. ==General information== The country calling code of Turkey is 90. * *Language digit: 0 (Direct Dialing) * *Language digit: 2 (Operator Assistance) *National (significant) number: 10 Digits. * * Area code: 3 digits * * Local subscriber’s number: 7 digits. * * Only exception in this is the call center numbers which start with 444, the call center numbers cannot be dialed with area code, they must be dialed with 7 digit from any phone (Landlines & Mobiles) in the country.
