Area Code 2934 – San Antonio Oeste, Río Negro

Overview of Area Code 2934

Area code 2934 is a geographic National Destination Code (NDC) assigned to the San Antonio Oeste region in the province of Río Negro, Argentina. This code covers the city of San Antonio Oeste and its surrounding localities, including the port town of San Antonio Este and the popular seaside resort of Las Grutas. The region is part of the Argentine telephone numbering plan, which follows ITU-T E.164 recommendations.

Geographic Coverage and Administration

The 2934 area code serves the eastern coastal area of Río Negro Province, along the Gulf of San Matías. Administratively, it falls under the jurisdiction of the Departamento de San Antonio. The principal city, San Antonio Oeste, is a key commercial and administrative hub, while Las Grutas attracts significant tourism during the summer months. This geographic code is managed by the Ente Nacional de Comunicaciones (ENACOM), Argentina's national telecommunications regulator.

Dialing Formats

For local calls within the same area code, subscribers dial the 7-digit subscriber number directly. For example, to call a landline in San Antonio Oeste from another local number, one would dial:

• Local call: 456 7890

For national long-distance calls from other parts of Argentina, the format requires the national trunk prefix 0, followed by the area code and the subscriber number:

• National call: 0 2934 456 7890

For international calls from abroad, callers must use the international access prefix (typically 00 or +), followed by Argentina's country code 54, the area code (without the leading 0), and the subscriber number:

• International call: +54 2934 456 7890

Overlay and Numbering Considerations

As of the latest ENACOM updates, there are no overlay codes for 2934. The area code remains a standalone geographic code, and number lengths are standardized. Subscriber numbers in this region are seven digits long, consistent with most geographic areas in Argentina. When dialing from a mobile phone within Argentina, the same national format (0 2934 ...) is used, though mobile users may also use the international format (+54 2934 ...) for clarity.

Caller Instructions

For local callers within the 2934 area, simply dial the 7-digit number. For callers elsewhere in Argentina, always include the trunk prefix 0 and the area code. For international callers, omit the trunk prefix 0 and use the +54 country code. It is important to note that while VoIP services may allow alternative dialing patterns, the standard PSTN rules apply for all traditional landline calls.
