Area Code 2231 – Hankavan/Hrazdan/Tsaghkadzor, Kotayk

Overview of Area Code 2231

Area code 2231 is a geographic National Destination Code (NDC) assigned to the Kotayk Province of Armenia, specifically serving the towns of Hankavan, Hrazdan, and Tsaghkadzor. This code is part of the Armenian numbering plan, which adheres to the ITU-T E.164 standard. The region is located in the central part of the country, north of the capital Yerevan, and is known for its mountainous terrain and as a popular destination for winter sports and wellness tourism.

Geographic Coverage and Administrative Jurisdiction

The 2231 area code covers the administrative district of Hrazdan, which is the capital of Kotayk Province. The code encompasses the urban centers of Hrazdan and Tsaghkadzor, as well as the smaller settlement of Hankavan. These localities are served by fixed-line PSTN (Public Switched Telephone Network) operators, including the national incumbent, and are subject to geographic number allocation rules. The area is not overlaid with another area code, meaning that local calls within the 2231 region are dialed using only the subscriber number, without the area code.

Dialing Formats and Procedures

For callers within Armenia, dialing a number in the 2231 area code requires the use of the national trunk prefix 0 followed by the area code and the subscriber number. The national significant number (NSN) for Armenia is eight digits, comprising the area code (excluding the trunk prefix) and a six-digit subscriber number. For example, to call a fixed-line number in Hrazdan, you would dial:

• 0 2231 XXXXXX (within Armenia)

For international callers, the Armenian country code +374 is used, followed by the area code without the leading zero. The international format is:

• +374 2231 XXXXXX (from abroad)

It is important to note that the trunk prefix '0' is only used for domestic calls and must be omitted when dialing from outside Armenia.

Caller Instructions

Local callers within the 2231 area code can dial the six-digit subscriber number directly without the area code. However, if calling from a mobile phone or from a different area code within Armenia, the full national format (0 2231 XXXXXX) is required. Foreign callers should always use the international format (+374 2231 XXXXXX) and ensure they have the correct country code. As with all geographic numbers, the tariff for calls to 2231 numbers depends on the caller's operator and the destination, with rates typically lower for fixed-line calls.

In summary, area code 2231 is a vital part of Armenia's telecommunications infrastructure, connecting the Kotayk region to the national and international networks. Understanding the correct dialing procedures ensures seamless connectivity for both residents and visitors.
