Area Code 2646 – Villa San Agustín, San Juan

Overview of Area Code 2646

Area code 2646 is a geographic National Destination Code (NDC) assigned to the town of Villa San Agustín and its surrounding areas within the San Juan Province of Argentina. This code is part of the national numbering plan administered under ITU-T E.164, and it is used for fixed-line (PSTN) services. The region is located in the central-western part of Argentina, in the foothills of the Andes, and is known for its agricultural production, particularly olives and grapes.

Geographic Coverage and Jurisdiction

The 2646 area code serves the Valle de Calingasta department, with Villa San Agustín being the principal locality. Other smaller settlements within the same exchange area may also fall under this code. Administratively, the area is part of the San Juan Province, and the national regulatory authority, ENACOM (Ente Nacional de Comunicaciones), oversees the allocation and management of this numbering resource.

Dialing Formats and Instructions

For callers within Argentina, the national trunk prefix 0 is used before the area code. The complete national significant number (NSN) for a local subscriber consists of the area code (2646) followed by a 6-digit subscriber number. Therefore, a domestic call from another province would be dialed as:

• 0 2646 XXX XXX (national format)

For international callers, the Argentine country code +54 is used, and the trunk prefix is omitted. The international dialing format is:

• +54 2646 XXX XXX (international format)

Local calls within the same area code do not require the area code; only the 6-digit subscriber number is dialed. However, if you are calling from a mobile phone, you may need to include the area code even for local calls, depending on your carrier's settings.

Overlay and Numbering Considerations

Currently, there is no overlay code for this area, meaning that 2646 is the sole area code for the region. However, as with many regions in Argentina, the number of fixed lines is limited, and the subscriber number length is fixed at 6 digits. The total length of a national significant number (excluding the trunk prefix) is 10 digits (area code + subscriber number), which is standard for geographic numbers in Argentina.

Caller Instructions

For callers from abroad, always replace the leading zero of the area code with the country code +54. For example, to call a number in Villa San Agustín from the United States, you would dial: 011 54 2646 XXX XXX (where 011 is the US international access code). For callers within Argentina, ensure you use the national trunk prefix 0 before the area code when dialing from outside the local area.

Understanding the correct dialing format is essential for both business and personal communication. As a geographic code, 2646 is tied to a specific location, which is important for emergency services, local business directories, and regulatory compliance.
