Area Code 466 – Artvin

Overview of Artvin's Geographic Code 466

The telephone area code 466 is the National Destination Code (NDC) assigned to the province of Artvin in the Eastern Black Sea region of Türkiye. This geographic code is part of the Turkish numbering plan, which adheres to ITU-T E.164 recommendations. The code covers the administrative province of Artvin, including its central district and all connected sub-districts and villages. Major settlements served by this code include the provincial capital Artvin, Hopa, Borçka, Arhavi, Yusufeli, Murgul, and Şavşat.

Geographic Coverage and Administrative Jurisdiction

The 466 area code is allocated exclusively to the province of Artvin, which is bordered by Georgia to the north and the provinces of Rize, Erzurum, and Ardahan. The region is known for its mountainous terrain and the Çoruh River valley. The code is administered by the Information and Communication Technologies Authority (BTK) of Türkiye and is assigned to fixed-line PSTN (Public Switched Telephone Network) services. As a geographic code, it is tied to a specific physical location, and the tariff for calls to 466 numbers is typically based on the distance from the caller's location.

Dialing Formats and Caller Instructions

For callers within Türkiye, the national dialing format requires the trunk prefix 0 followed by the area code and the subscriber number. The subscriber number length for Artvin is typically 7 digits, making the total national number length 10 digits (excluding the initial 0). For example, to call a fixed line in Artvin from Istanbul, you would dial: 0 466 XXX XX XX.

For international callers, the Turkish country code +90 is used, and the leading trunk prefix '0' is omitted. The international format is: +90 466 XXX XX XX. For instance, a caller from the United States would dial: 011 90 466 XXX XX XX, while a caller from the United Kingdom would dial: 00 90 466 XXX XX XX.

Overlay and Numbering Considerations

As of the latest updates, there are no overlay codes for the 466 area code, meaning that the code is not shared with other geographic regions. The numbering capacity is sufficient for the population and business density of Artvin. However, with the increasing adoption of VoIP and mobile services, the distinction between geographic and non-geographic numbers is becoming more blurred. Nevertheless, 466 numbers remain primarily associated with fixed-line services, and they are not portable to mobile networks in the traditional sense, though number portability within fixed networks is possible.

When dialing locally within Artvin, it is common to use the short format without the area code for local calls, but this practice is being phased out in favor of mandatory 10-digit dialing in many regions. To ensure connectivity, it is always recommended to use the full national format (0 466 XXX XX XX) even for local calls.
