Area Code 2837 – Sisian, Syunik

Geographic Overview

The area code 2837 is a geographic National Destination Code (NDC) assigned to the town of Sisian and its surrounding administrative district within the Syunik Province of the Republic of Armenia. Syunik is the southernmost province of Armenia, bordering Iran to the south and Azerbaijan to the east. Sisian serves as a local administrative and cultural hub for the region, situated along the Vorotan River at an elevation of approximately 1,600 meters. The code covers the urban center of Sisian, as well as nearby rural communities and settlements that fall within the Sisian municipal jurisdiction.

Dialing Procedures

To call a fixed-line subscriber in Sisian from within Armenia, you must dial the trunk prefix 0, followed by the area code 2837, and then the subscriber's 5-digit local number. The complete national format is: 0 2837 XX XXX (where X represents the local digits). For example, a local number such as 2 34 56 would be dialed as 0 2837 23456 from any other location in Armenia.

For international callers, the Armenian country code is +374. You must drop the leading trunk prefix '0' and dial: +374 2837 XX XXX. Using the same example, an international caller would dial +374 2837 23456.

When dialing from a mobile phone within Armenia, the same national format applies (0 2837 XX XXX). However, if you are physically located within the Sisian area and calling another local fixed-line number, you may be able to use abbreviated local dialing (without the area code), depending on your operator's settings. For clarity and reliability, it is recommended to always use the full national format.

Regulatory and Technical Notes

Armenia's numbering plan is administered by the Public Services Regulatory Commission (PSRC) under the framework of ITU-T E.164. Geographic area codes in Armenia are structured as 2 to 4 digits, and the total length of a national significant number (NDC + subscriber number) is 8 digits. The 2837 code is part of the 28x series assigned to Syunik Province, with other codes covering towns such as Goris, Kapan, and Meghri.

As of the latest updates, there are no overlay codes or 10-digit dialing requirements in Armenia. The trunk prefix '0' is mandatory for all domestic calls to geographic numbers from outside the local area. Calls to Sisian from foreign countries require the use of the international access code of the originating country (e.g., 011 from the US, 00 from most European countries) followed by 374 and the area code without the leading '0'.

While fixed-line services in Sisian are primarily provided by ArmenTel (Beeline) and other licensed operators, the area code is not operator-specific. Subscriber numbers are allocated to the geographic location, not to a particular service provider. This means that number portability may allow a subscriber to retain their 2837 number even if they switch to a different fixed-line operator, though the geographic tie remains.
