Telephone numbers in Turkey

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.

Country	Turkey
Continent	Europe, Asia
Numbering plan type	Closed
NSN length	10
Format	0 (xxx) xxx xx xx

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 Turkey (540-549), and Türk Telekom (500-509 and 550-559).^[1]

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

Description

The country calling code of Turkey is 90.^[2]

• Language digit^{[notes 1]}: 0 (Direct Dialing)
• Language digit: 2 (Operator Assistance)
• National (significant) number: 10 digits
  • Area code: 3 digits
  • Local subscribers' number: 7 digits.^{[notes 2]}
  • 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 a caller dials a call center number including the area code, the IVR system instructs them to redial the number without the area code.
• Dialing procedure:
  • A call from another country would have the following dialing format:

International call prefix +	90 +	Area code +	Subscribers' number
(00) or +	90	(3 Digit)	(7 Digit)

Example: + 90 312 213 2965
International call prefix +	90 +	Area code +	Subscribers' number
+	90	312	213 2965

Notes

1. In Turkish telephony (historically in PTT and Türk Telekom routing tables), the language digit determined which operator or announcement language the caller would hear
2. Subscribers' numbers cannot be prefaced with the number 1. 1 is only to be used for certain special services.
3. 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.
