Area Code 2902 – Río Turbio, Santa Cruz

Overview of Area Code 2902

Area code 2902 is a geographic National Destination Code (NDC) assigned to the city of Río Turbio and its surrounding localities in the province of Santa Cruz, Argentina. This region is part of the southern Patagonian zone, known for its coal mining history and proximity to the Chilean border. The code serves the urban area of Río Turbio, as well as nearby towns such as Julia Dufour and Rospentek, within the department of Güer Aike.

Geographic Coverage and Administration

Río Turbio is the administrative and commercial hub for the area, located approximately 270 kilometers west of Río Gallegos, the provincial capital. The numbering area falls under the jurisdiction of the Ente Nacional de Comunicaciones (ENACOM), which regulates Argentina's public switched telephone network (PSTN). The 2902 code is classified as a geographic number, meaning that the tariff and routing are based on the physical location of the fixed-line subscriber.

Dialing Formats and Instructions

For callers within Argentina, the national dialing format requires the use of the trunk prefix 0, followed by the area code and the subscriber number. For example, to call a fixed line in Río Turbio with the number 456789, you would dial:

• National (from anywhere in Argentina): 0 2902 456789
• International (from outside Argentina): +54 2902 456789

When dialing locally within the same area code, the area code may be omitted, and only the seven-digit subscriber number is used (e.g., 456789). However, for clarity and to avoid misdialing, it is recommended to use the full national format, especially when calling from mobile networks.

Overlay and Numbering Considerations

As of the latest ENACOM numbering plan, there is no overlay code for 2902; the area code is unique to this region. Subscriber numbers are seven digits long, and the total length of a national significant number (NSN) is ten digits, including the area code. This is consistent with Argentina's E.164 numbering plan, where the country code is +54, followed by a two- to four-digit area code and a subscriber number.

Caller Instructions

For local callers within Río Turbio, dialing the subscriber number alone is sufficient. For callers from other Argentine provinces, you must include the trunk prefix 0 before the area code. For international callers, always replace the trunk prefix with the country code +54, and omit the leading zero of the area code. For example, a caller from the United States would dial 011 54 2902 456789.

It is important to note that while fixed-line numbers in this area are geographic, many residents and businesses also use mobile services, which have their own non-geographic codes (e.g., 2902 is not used for mobile). Mobile numbers in Argentina start with 15 after the area code when dialed nationally, but this is not applicable to the 2902 fixed-line prefix.
