Area Code 352 – Kayseri

Overview of Area Code 352 (Kayseri, Türkiye)

Area code 352 is the National Destination Code (NDC) assigned to the province of Kayseri in the Central Anatolia region of Türkiye. It covers the provincial capital, Kayseri, and its metropolitan districts, including Melikgazi, Kocasinan, Talas, Develi, Yahyalı, Bünyan, and İncesu, as well as surrounding towns and villages. As a geographic code, it is tied to the PSTN infrastructure of the region, serving both fixed-line subscribers and, in some cases, VoIP-based local numbers.

Dialing Formats

When calling a Kayseri landline from within Türkiye, you must include the trunk prefix 0 followed by the area code and the 7-digit subscriber number. The national format is:

• 0 352 XXX XX XX (domestic call)

For international callers, the Turkish country code (+90) replaces the trunk prefix, and the leading 0 is omitted. The international format is:

• +90 352 XXX XX XX (from abroad)

For example, to call a Kayseri landline with the number 123 45 67, you would dial:

• From Istanbul: 0 352 123 45 67
• From the United States: +90 352 123 45 67

Geographic Coverage and Administrative Jurisdiction

Kayseri is one of Türkiye's major industrial and commercial hubs, known for its organized industrial zones and historical sites. The area code 352 is administered under the Information and Communication Technologies Authority (BTK) and is assigned exclusively to the province. The numbering plan follows the ITU-T E.164 recommendation, ensuring global interoperability.

Overlay and Numbering Considerations

Currently, there is no overlay code for Kayseri; all fixed-line numbers within the province share the 352 code. Subscriber numbers are 7 digits long, and the total length of a national significant number (NSN) is 10 digits (including the leading 0). As of the latest BTK regulations, no changes to the geographic code structure are anticipated in the near future.

Caller Instructions

For local callers within Kayseri, it is common to dial only the 7-digit subscriber number when calling within the same area code, though the full national format is always valid. However, for clarity and to avoid misdialing, it is recommended to use the full national format. For foreign callers, always replace the trunk prefix 0 with the country code +90 and drop the leading 0 of the area code.

Kayseri's area code is also used for some VoIP and internet telephony services that provide local numbers, but these are not geographically restricted and may be routed via IP networks. Nevertheless, the code remains a geographic identifier for regulatory and routing purposes.
