Area Code 3873 – Tartagal, Salta

Overview of Area Code 3873

Area code 3873 is a geographic National Destination Code (NDC) within the Argentine national numbering plan, assigned to the city of Tartagal and its surrounding areas in the province of Salta, in the northwest region of the country. This code is part of the Northwest Argentina telecommunications region and is administered under the oversight of the Ente Nacional de Comunicaciones (ENACOM), the national regulatory body.

Geographic Coverage and Jurisdiction

The 3873 code serves the department of General José de San Martín, with Tartagal as the primary urban center. It also covers nearby towns and rural communities, including General Mosconi (also known as Vespucio), Aguaray, and smaller settlements along the Bermejo River basin. This area is notable for its proximity to the Bolivian border and its role in the hydrocarbon industry.

Dialing Formats and Usage

For local calls within Tartagal and the immediate area, callers can typically dial the subscriber number directly (usually 7 digits) without the area code. However, for calls from other regions within Argentina, the full national format is required:

• National dialing (from within Argentina): 0 3873 4XX XXXX (where the leading 0 is the national trunk prefix, followed by the area code and the subscriber number).
• International dialing (from outside Argentina): +54 9 3873 4XX XXXX for mobile numbers or +54 3873 4XX XXXX for fixed lines. Note that for calls to Argentine mobile numbers, the mobile-specific prefix 9 is inserted after the country code.

For example, a local fixed-line number might be 3873 421 2345. To call this number from Buenos Aires, you would dial 0 3873 421 2345. From the United States, you would dial +54 3873 421 2345.

Overlay and Numbering Considerations

As of the latest ENACOM updates, there is no overlay code for 3873; the area code remains exclusive to the Tartagal region. Subscriber numbers are typically 7 digits long, and the area code is mandatory for all calls originating outside the local calling area. For callers within the same region, omitting the area code may work, but it is always safer to use the full national format to avoid misdialing.

Caller Instructions

For local callers: if you are within the 3873 area, you can dial the 7-digit subscriber number directly for local calls. For long-distance calls within Argentina, you must prefix with 0 and the area code. For international callers, always use the country code +54 followed by the area code (without the leading 0) and the subscriber number. Remember to replace the plus sign with your country's international exit code (e.g., 011 in the US, 00 in many European countries).
