Area Code 312 – Gyumri, Shirak

Overview of Area Code +374 312

Area code 312 is a geographic National Destination Code (NDC) within the Armenian numbering plan, assigned to the city of Gyumri and the surrounding Shirak Province. Gyumri, the second-largest city in Armenia, serves as the administrative and economic hub of the region. This code is used for fixed-line (PSTN) services, including traditional copper lines and some VoIP-based fixed services that are registered to a physical address in the area.

Geographic Coverage and Administrative Jurisdiction

The 312 code covers the urban area of Gyumri and extends to several towns and villages within Shirak Province, such as Artik, Maralik, and Akhuryan. The jurisdiction follows the administrative boundaries of the Shirak Province, which is located in the northwestern part of Armenia, bordering Georgia and Turkey. Calls to this code are routed to physical exchanges that are geographically tied to the region.

Dialing Formats and Caller Instructions

Understanding the correct dialing format is essential for both domestic and international callers.

• Domestic calls (within Armenia): To call a fixed-line number in Gyumri from another Armenian city, dial 0 312 XXX XXX. The leading '0' is the trunk prefix used for national calls. The subscriber number is seven digits long, but the NDC (312) is not included when dialing within the same area code.
• International calls (from outside Armenia): Callers should dial the international access prefix (e.g., '00' or '+'), followed by the Armenian country code 374, then the area code 312 without the leading '0', and the seven-digit subscriber number. The complete international format is +374 312 XXX XXX.
• Local calls within Gyumri: For calls between two fixed-line numbers within the same area code, local dialing may allow omitting the area code, but this depends on the specific operator's configuration. In most cases, using the full national format is recommended for reliability.

Practical Examples

Suppose a subscriber in Gyumri has the number 456 7890. To call this number from Yerevan, you would dial: 0 312 456 7890. From the United States, you would dial: 011 374 312 456 7890 (or use the '+' shortcut on mobile phones: +374 312 456 7890).

Overlay and Numbering Considerations

As of the latest ITU-T recommendations, there is no overlay code for Gyumri; the 312 code remains the sole geographic code for the region. However, number portability is available in Armenia, allowing subscribers to retain their numbers when switching operators, but geographic numbers are generally tied to the physical location. If you are calling a mobile number that was originally a fixed-line number, the routing may differ, but the dialing format remains the same.

Important Notes for Callers

When placing international calls, always verify the exact number of digits. Armenian fixed-line numbers are typically seven digits long after the area code. Ensure you do not drop any leading zeros when dialing from abroad. For further assistance, consult your telecom provider for any specific dialing requirements.
