Dialing Formats

• Domestic calls within Argentina: Dial 0 (trunk prefix) followed by the area code and subscriber number: 0 3574 456789.
• Local calls within the same area code: Dial the subscriber number directly, omitting the area code and trunk prefix. For instance, 456789.
• International calls from abroad: Dial your country's exit code (e.g., 011 from the US), then 54 (country code), then 3574, and finally the local number: 011 54 3574 456789.

Geographic Coverage and Administration

The 3574 area code is administered under the Argentine national numbering plan, overseen by the Ente Nacional de Comunicaciones (ENACOM). It is classified as a geographic code, meaning it is tied to a specific physical location. The region is primarily agricultural, with dairy farming and grain production being key economic activities. The city of Río Primero serves as the administrative and commercial hub for the department.

Overlays and Numbering Considerations

As of the latest ENACOM updates, there are no overlay codes for this area. However, due to the growth of telecommunications services, some numbers may be assigned to VoIP providers that offer fixed-line services in the region. These numbers are still considered geographic and follow the same dialing rules. When calling from a mobile phone within Argentina, the same trunk prefix (0) and area code are used, but mobile users may need to include the area code even for local calls if they are not in the same exchange area.

Caller Instructions

For callers within Argentina, always include the trunk prefix 0 when dialing from a different area code. For international callers, ensure you use the correct exit code for your country and then dial 54 3574 followed by the local number. It is important to note that Argentine fixed-line numbers do not require a leading zero after the country code; the zero is only used domestically as the trunk prefix.
