Area Code 264 – Sakarya

Overview of Sakarya's Geographic Code +90 264

The country calling code +90 is assigned to Türkiye under the ITU-T E.164 international numbering plan. Within this framework, the national destination code (NDC) 264 is a geographic area code allocated to the province of Sakarya, located in the Marmara region of northwestern Turkey. This code is used for fixed-line (PSTN) services and is administered by the Information and Communication Technologies Authority (BTK).

Coverage and Administrative Jurisdiction

The +90 264 code covers the entire Sakarya Province, including its administrative center, Adapazarı, and other districts such as Serdivan, Erenler, Arifiye, Akyazı, Hendek, Karasu, Kocaali, Sapanca, Ferizli, Söğütlü, Kaynarca, Karapürçek, and Taraklı. The code is used for all fixed-line numbers within the province, regardless of the specific district, and is not overlaid with any other area code.

Dialing Formats

For local callers within Türkiye, the national trunk prefix 0 is used before the area code. The full national format is 0 264 XXX XX XX, where 'XXX XX XX' represents the 7-digit subscriber number. For example, a local call to a fixed line in Adapazarı would be dialed as 0264 123 45 67.

For international callers, the Turkish country code +90 is used, and the leading '0' is omitted. The international format is +90 264 XXX XX XX. For instance, a caller from abroad would dial +90 264 123 45 67 to reach the same number.

Caller Instructions

Local callers: When calling a Sakarya fixed-line number from another fixed or mobile line within Türkiye, dial the national trunk prefix '0', followed by the area code '264', and then the 7-digit subscriber number. For example, 0264 123 45 67.

International callers: Dial the international access prefix (e.g., '00' from most countries, or '+' from mobile phones), followed by the Turkish country code '90', the area code '264' (without the leading '0'), and the 7-digit subscriber number. For example, +90 264 123 45 67.

Numbering and Regulatory Notes

Fixed-line numbers in Sakarya are 12 digits in international format, including the country code and area code. The BTK regulates number allocation, and as of recent years, there are no plans for an overlay code in Sakarya. Subscriber numbers are assigned to fixed-line operators (e.g., Türk Telekom) and alternative carriers. When calling from a mobile phone, the same national dialing rules apply, but note that calls to fixed lines may be subject to different tariffs than mobile-to-mobile calls.
