Area Code 3572 – Río Segundo, Córdoba

Overview of Area Code 3572

Area code 3572 is a geographic National Destination Code (NDC) within the Argentine numbering plan, assigned to the city of Río Segundo and its surrounding localities in the province of Córdoba. This code is part of the national telephone network administered under ITU-T E.164 guidelines, specifically within the +54 country calling code for Argentina. The region is situated in the central part of the country, approximately 35 kilometers east of the provincial capital, Córdoba City, and forms part of the Paraná–Plata basin's economic corridor.

Geographic Coverage and Jurisdiction

The 3572 code serves the administrative jurisdiction of the Río Segundo Department, which includes the municipal area of Río Segundo itself, along with nearby towns such as Pilar, Costa Sacate, and Rincón. These localities are primarily residential and agricultural, with a growing industrial presence due to their proximity to major transportation routes, including National Route 9 and the Córdoba–Rosario highway. The region falls under the regulatory oversight of the Ente Nacional de Comunicaciones (ENACOM), which manages numbering resources in Argentina.

Dialing Formats and Caller Instructions

For callers within Argentina, the local dialing format requires the prefix 0 followed by the area code and subscriber number. For example, to call a landline in Río Segundo, you would dial 0-3572-XXXXXX, where XXXXXX represents the six-digit local number. For international callers, the format is +54 3572 XXXXXX, omitting the leading zero of the trunk prefix. It is important to note that Argentina uses a closed dialing plan for fixed lines; therefore, the area code must always be dialed, even for calls within the same locality. When calling from a mobile phone within Argentina, the same national format applies, but the call will be routed as a fixed-to-mobile or mobile-to-fixed call, depending on the originating network.

Overlay and Numbering Considerations

As of the latest ENACOM updates, area code 3572 does not have an overlay code, meaning it retains its exclusive geographic assignment. However, subscribers may have the option to port their numbers to other service providers, including VoIP operators, while retaining the geographic prefix. This is permitted under Argentina's number portability regulations, which apply to both fixed and mobile services. For businesses, having a 3572 number reinforces a local presence in the Río Segundo area, which can be advantageous for customer trust and regional marketing.

Practical Usage and Cost Implications

From a cost perspective, calls to 3572 numbers are typically billed as national long-distance within Argentina, unless the caller is within the same local calling area. For international callers, charges vary based on their carrier's international tariff. It is advisable to check with your service provider for specific rates. For those traveling to the region, using a local SIM card or VoIP service can reduce costs.
