Area Code 10 – Yerevan/Jrvezh

Overview of Armenia's Geographic Code 10

In Armenia's national numbering plan, the geographic area code 10 is assigned to the capital city, Yerevan, and the adjacent community of Jrvezh. This code is used for fixed-line (PSTN) services within this metropolitan area. As a geographic code, it is tied to a specific physical location, meaning that calls to numbers with this prefix are routed to the Yerevan/Jrvezh exchange area.

Dialing Formats

To call a fixed-line number in Yerevan or Jrvezh, the dialing format depends on the caller's origin. Within Armenia, callers must dial the trunk prefix 0 followed by the area code and the subscriber number. For example, a local call to a number in Yerevan would be dialed as:

• 0 10 XXX XXX (within Armenia)

From outside Armenia, callers must use the international prefix (typically 00 or +), followed by Armenia's country calling code 374, then the area code without the leading trunk prefix, and the subscriber number. For instance:

• +374 10 XXX XXX (international format)

Note that the subscriber number for Yerevan/Jrvezh is typically 6 digits long, making the total national significant number (NSN) 8 digits when the area code is included (0 10 XXX XXX).

Geographic Coverage and Administration

Yerevan is the largest city and administrative capital of Armenia, serving as the political, economic, and cultural hub. Jrvezh is a small community located in the Kotayk Province, but it is part of the Yerevan telephony zone for numbering purposes. The area code 10 is one of several codes used for Yerevan; others include 11, 12, and 91, which were introduced to accommodate the growing demand for fixed-line services. However, 10 remains one of the most widely recognized codes for the capital.

Caller Instructions

For callers within Armenia, it is essential to include the trunk prefix 0 before the area code when dialing from a different fixed-line zone or from a mobile phone. For example, to call a Yerevan number from another Armenian city, dial 0 10 XXX XXX. Mobile callers within Armenia should also use the same format, as mobile networks require the full national number.

For international callers, always replace the trunk prefix with the country code +374. Thus, a call from the United States to Yerevan would be dialed as 011 374 10 XXX XXX (using the US exit code) or simply +374 10 XXX XXX on a mobile phone.

Overlay and Numbering Considerations

Armenia has implemented overlay codes for Yerevan to expand numbering capacity. This means that multiple area codes (10, 11, 12, 91) serve the same geographic area. As a result, local calls between these codes may require the area code to be dialed even for calls within Yerevan. However, the standard format remains consistent: dial 0 plus the area code and subscriber number for domestic calls.

For businesses and residents, it is important to note that number portability may allow a subscriber to retain their number when moving within Armenia, but the geographic code generally indicates the original location of the line. Always verify the correct dialing format with your service provider if you encounter issues.
