Area Code 3571 – Río Tercero, Córdoba

Overview of Area Code 3571

Area code 3571 is a geographic National Destination Code (NDC) within the Argentine national numbering plan, assigned to the city of Río Tercero and its surrounding localities in the province of Córdoba. This code is used for fixed-line (PSTN) services, and it is part of the broader Córdoba province numbering scheme, which is divided into several area codes to reflect the country's internal administrative and telecommunication boundaries.

Geographic Coverage and Jurisdiction

The 3571 area code covers Río Tercero, a city located in the central-eastern part of Córdoba Province, approximately 107 km south of the provincial capital, Córdoba City. It also serves nearby towns and rural areas within the same telephone exchange region, such as Almafuerte, Corralito, and Las Perdices. The region is part of the Departamento Tercero Arriba, and the numbering plan is administered by the Ente Nacional de Comunicaciones (ENACOM), the Argentine communications regulator.

Dialing Formats

When calling a fixed-line number in Río Tercero, the local number is typically 6 to 7 digits long. The full national (domestic) dialing format requires the trunk prefix 0 followed by the area code and the subscriber number:

• Domestic call (from within Argentina, outside the area): Dial 0-3571-XXX XXX.
• International call (from outside Argentina): Dial your country's exit code, then 54 (Argentina's country calling code), then 3571, and then the subscriber number: +54 3571 XXX XXX.
• Local call (within the same area code): Dial only the subscriber number (7 digits) if you are within the same exchange; otherwise, use the national format.

For example, if the local number is 4567890, you would dial 03571 4567890 from another Argentine city, and +54 3571 4567890 from abroad.

Overlay and Numbering Considerations

As of the latest ENACOM updates, there is no overlay code for 3571; the area code remains exclusive to this geographic region. However, due to the growth of mobile and VoIP services, some numbers may be routed over IP networks, but the geographic significance of the code remains for fixed-line identification. Callers should always verify the correct number length and use the appropriate international prefix when dialing from outside Argentina.

Practical Guidance for Callers

For local callers within Argentina, always include the trunk prefix 0 when dialing from a different area code. For international callers, it is essential to replace the trunk prefix with the +54 country code. This ensures proper routing through the PSTN. If you are calling a mobile phone in the same region, note that mobile numbers use different prefixes (starting with 15 after the area code for domestic calls) and are not part of the fixed-line 3571 numbering.
