Area Code 15 – Yerevan

Overview of Armenia's Geographic Code 15

In Armenia's national numbering plan, the prefix 15 is designated as a geographic area code serving the capital city, Yerevan. This code is part of the country's E.164-compliant numbering structure, where the full international format for a Yerevan landline number is +374 15 XXX XXX. The code is assigned to fixed-line services within the Yerevan administrative jurisdiction, which includes the city's central districts and surrounding suburban areas that fall under the Yerevan municipality.

Geographic Coverage and Administrative Jurisdiction

Yerevan, the largest city in Armenia, is the primary economic, political, and cultural hub. The 15 prefix is used exclusively for geographic numbers within this region, distinguishing it from other Armenian area codes such as 10 (also Yerevan), 31 (Kotayk), and 41 (Armavir). The Armenian Telecommunications Regulatory Commission (PSRC) oversees the allocation of these codes, ensuring that each geographic prefix corresponds to a specific administrative territory. For Yerevan, multiple codes exist due to the high demand for fixed-line services, with 15 being one of the newer assignments introduced to accommodate growth.

Dialing Formats and Caller Instructions

For local callers within Armenia, dialing a Yerevan number with prefix 15 requires the national format: 015 XXX XXX (the leading '0' is used for domestic trunk access). For example, to call a Yerevan number 123 45 67 from another Armenian city, you would dial 015 123 45 67. International callers must use the full international format: +374 15 123 45 67 (or 011 374 15 123 45 67 from North America). When dialing from a mobile phone in Armenia, the same national format applies, though some mobile operators may allow direct dialing without the trunk prefix depending on the user's settings.

Overlay and Numbering Considerations

Yerevan has multiple area codes, including 10, 11, 12, and 15, which function as overlays for the same geographic region. This means that a single physical location may have numbers from different prefixes, and local calls between these codes are not considered long-distance. However, the 15 prefix is specifically used for newer fixed-line assignments, often for VoIP-based fixed services that are location-independent but still classified as geographic. As a result, users may encounter numbers with the 15 prefix that are not tied to a specific physical address, but they are still billed as local calls when dialed from Yerevan.

Practical Examples for Callers

• Local call (within Armenia): 015 234 56 78
• International call (from abroad): +374 15 234 56 78
• From a mobile in Armenia: 015 234 56 78 (or +374 15 234 56 78 if using international format)

When dialing from outside Armenia, always replace the leading '0' with the country code +374. Ensure you have the correct international exit code for your country (e.g., 00 from most European countries, 011 from the US/Canada).
