Telephone numbers in Turkey went from six (2+4) to seven digits (3+4) circa 1988. There used to be more than 5,000 local area codes of varying lengths (one to five digits) 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 (212 for the European side, and 216 for the Asian side).

The prefixes for the three major Turkish operators are as follows: Turkcell (530-539, 561 61, 516 16), Vodafone (540-549), and Türk Telekom (500-509 and 550-559).^[1][2]

On 30 August 1993, local numbers in most areas were changed in conjunction with a new numbering plan.

The country calling code of Turkey is 90.

• Language digit:^{[clarification needed]} 0 (Direct Dialing)
• Language digit: 2 (Operator Assistance)
• National (significant) number: 10 digits
  • Area code: 3 digits
  • Local subscribers' number: 7 digits.
  • Only exceptions to this are call center numbers which start with 444, which cannot be dialed like area codes. They must be dialed with 7 digits from any phone in the country. The number format is 444 XX XX. To dial call center numbers from other countries, the number must be dialed as country code + call center number like 90 444 XX XX. If you dial a call center number with the area code an IVR says you must not use the area code.
• Dialing procedure:
  • A call from another country would have the following dialing format:

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. 1 is only to be used for certain special services.

Ankara, İstanbul and İzmir DMS-300 International Exchanges accept:

There are two international operator centers in Turkey, Ankara and İstanbul. Each one of these centers provides operator telephone services according to ITU/T dialing:

L/D + code11 + ST (random)

L/D + code12 + 312 + ST (Ankara)

L/D + code12 + 212 + ST (İstanbul)

L/D: language digit 2 English

C11: operator assistance

C12: international transits

ST: stop pulse

The operators of the international exchanges in Ankara and Istanbul are available under C11 and C12.

Note: These are the codes that wireless operators in Turkey assign to new subscribers. Because of mobile number portability, a subscriber's telephone number may not accurately reflect their actual operator.
