Area Code 3576 – Arroyito, Córdoba

Overview of Area Code 3576

Area code 3576 is a geographic National Destination Code (NDC) assigned to the city of Arroyito and its surrounding localities in the province of Córdoba, Argentina. This code is part of the national numbering plan administered by the Ente Nacional de Comunicaciones (ENACOM), following ITU-T E.164 recommendations. Arroyito is a significant industrial and agricultural hub in the San Justo Department, located approximately 130 kilometers east of the provincial capital, Córdoba City.

Geographic Coverage and Jurisdiction

The 3576 area code covers Arroyito and several nearby towns and rural areas, including but not limited to La Tordilla, Colonia San Bartolomé, and El Fuertecito. Administratively, these communities fall under the jurisdiction of the Municipality of Arroyito and the broader San Justo Department. The region is known for its agro-industrial activities, particularly dairy and grain production, as well as the presence of major food processing plants.

Dialing Formats and Instructions

For local callers within the 3576 area code, calls to another local number are placed using the 7-digit subscriber number alone (e.g., 452345). For callers from other Argentine provinces or mobile networks, the full national format must be used: 0 3576 452345. The leading 0 is the national trunk prefix, and 3576 is the area code. International callers should dial the Argentine country code +54, followed by the area code without the leading 0, and then the subscriber number: +54 3576 452345. It is important to note that Argentina uses a closed dialing plan for geographic numbers, meaning the area code is always required for calls from outside the local area, even for mobile-to-landline calls.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 3576 area. The subscriber numbers are typically 7 digits long, and the total length of a national significant number (NSN) is 10 digits (area code + subscriber number). As of recent ENACOM regulations, there are no plans for an overlay in the near future, but users should be aware that any changes would be announced well in advance. For callers using VoIP or mobile services, it is essential to include the area code to ensure proper routing, as per the national numbering plan.

Practical Tips for Callers

When calling from abroad, always replace the trunk prefix 0 with the international access code of your country (e.g., 00 or +) and then dial 54. For example, from the United States, you would dial 011 54 3576 452345. If you are using a mobile phone, you can simply use the plus sign: +54 3576 452345. Ensure you have the correct subscriber number, as omitting the area code when calling from outside the local area will result in a failed call.
