Area Code 2836 – Sisian, Syunik

Overview of Area Code 2836

Area code 2836 is a geographic National Destination Code (NDC) within the Armenian numbering plan, assigned to the town of Sisian and its surrounding rural communities in the Syunik Province (Syunik Marz) of the Republic of Armenia. This code is used for fixed-line (PSTN) services, including traditional copper-line telephony and, in some cases, fixed wireless access (FWA) that is registered to a physical address within the Sisian exchange area. As with all Armenian geographic codes, the prefix is not portable to other regions; it remains tied to the Sisian local exchange.

Geographic Coverage and Administrative Jurisdiction

Sisian is the administrative center of the Sisian Municipality, which encompasses the town and roughly 30 adjacent villages, including Aghitu, Ashotavan, and Karashen. The area code 2836 serves the entire municipality, covering a mountainous terrain along the Vorotan River valley. The region is known for the historic Sisian Fortress and the nearby Zorats Karer (Karahunj) archaeological site. The code is managed under the jurisdiction of the Public Services Regulatory Commission of Armenia, which oversees the national numbering plan in accordance with ITU-T E.164 recommendations.

Dialing Procedures

To call a fixed-line number in Sisian from within Armenia, you must dial the trunk prefix 0, followed by the area code 2836 and the subscriber's 5-digit local number. The full national significant number (NSN) is 8 digits, excluding the leading trunk prefix. For example, if the local number is 2 34 56, you would dial: 0 2836 2 34 56.

From outside Armenia, you need to dial the international access prefix (typically 00 or +), then the country code 374, followed by the area code 2836 and the local number, omitting the trunk prefix. The same example would be dialed as: +374 2836 2 34 56.

It is important to note that Armenia has adopted a closed dialing plan for fixed lines: the area code must always be included, even for local calls within Sisian. There is no overlay code for this region, so no additional digits are required.

Caller Instructions

Local callers within Sisian should always dial the full national format (0 2836 XXX XX) to ensure proper routing. International callers must replace the leading zero with the +374 country code. For calls from mobile phones within Armenia, the same national format applies. If you are uncertain about the number length, note that all Armenian fixed-line numbers have 8 digits after the trunk prefix (0) or country code (+374).
