Area Code 2830 – Sisian, Syunik

Overview of Area Code 2830

Area code 2830 is a geographic National Destination Code (NDC) assigned to the town of Sisian and its surrounding rural communities within the Syunik Province of Armenia. Syunik is the southernmost province of the country, bordering Iran to the south and Azerbaijan to the east. Sisian serves as a regional administrative and economic hub, situated on the Vorotan River at an elevation of approximately 1,600 meters. The code is part of the Armenian public switched telephone network (PSTN) and is used exclusively for fixed-line services in this area.

Geographic Coverage and Jurisdiction

The 2830 prefix covers Sisian and nearby villages such as Aghitu, Angeghakot, Shaki, and Tolors, all within the Syunik Province. The area is known for its historical landmarks, including the Zorats Karer archaeological site (often called the Armenian Stonehenge) and the Shaki Waterfall. Administratively, the code falls under the jurisdiction of the Syunik Regional Administration, which oversees local telecommunications infrastructure. The numbering area is geographically isolated by the Zangezur Mountains, which historically influenced the deployment of dedicated trunk lines to the regional capital, Kapan.

Dialing Formats and Instructions

To call a fixed-line number in Sisian from within Armenia, subscribers must dial the trunk prefix 0, followed by the area code 2830, and then the subscriber's 5-digit local number. The complete national format is: 0 283 0X XX XX (where X represents the local digits). For example, a local number might be 0 2830 12345.

For international callers, the Armenian country code is +374. Therefore, the international dialing format is: +374 2830 12345. Note that the leading '0' of the national trunk prefix is omitted when dialing from abroad. Callers from other countries should replace the '+' with their international access code (e.g., '011' from the US, '00' from most European countries).

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan updates, there is no overlay code for the Sisian area. The 2830 code is unique to this geographic region, and number lengths are fixed at 8 digits (including the area code) for national dialing. Mobile numbers in Armenia use separate non-geographic prefixes (e.g., 77, 91, 93, 94, 98) and are not affected by this geographic code. When calling a Sisian fixed line from a mobile phone, the same national format (0 2830 ...) applies.

For callers within Syunik Province, local calls may be dialed using only the subscriber number in some cases, but it is recommended to always use the full national format to avoid routing errors, especially from VoIP or mobile networks. The Armenian Telecommunications Regulatory Commission (PSRC) oversees the allocation and management of geographic codes, ensuring that 2830 remains reserved for Sisian's fixed-line services.
