Area Code 3584 – La Carlota, Córdoba

Overview of Area Code 3584

Area code 3584 is a geographic National Destination Code (NDC) within the Argentine national numbering plan, assigned under the country calling code +54. It serves the city of La Carlota and its surrounding rural districts in the southeastern part of Córdoba Province. This region is part of the Pampas agricultural heartland, with La Carlota acting as a commercial and administrative hub for nearby smaller towns such as Reducción, Bengolea, and Ucacha.

Geographic Coverage and Jurisdiction

The 3584 numbering area falls under the jurisdiction of the Ente Nacional de Comunicaciones (ENACOM), Argentina's national telecommunications regulator. The coverage zone is primarily within the Presidente Roque Sáenz Peña Department of Córdoba Province. Unlike mobile prefixes, this is a fixed-line prefix tied to physical telephone exchanges, and calls to numbers within this area are routed over the public switched telephone network (PSTN) or via fixed wireless local loop services.

Dialing Formats and Procedures

For callers within Argentina, the national trunk prefix 0 must be dialed before the area code when calling from outside the local calling area. The full national significant number (NSN) for a subscriber in La Carlota consists of the area code (3584) followed by a 6-digit local number, resulting in a total of 10 digits after the trunk prefix. For example, a local number such as 452367 would be dialed as:

• National call (from other Argentine cities): 0 3584 452367
• International call (from abroad): +54 3584 452367

Within the same local area, callers can typically dial just the 6-digit subscriber number without the area code. However, due to the implementation of overlay codes in some regions, it is advisable to confirm local dialing habits with the service provider.

Caller Instructions

For local callers within La Carlota, direct dialing of the 6-digit number is standard. For callers from other parts of Argentina, the national trunk prefix 0 is mandatory. For international callers, the Argentine country code +54 must be used, followed by the area code without the leading 0. Ensure that the plus sign (+) is included when dialing from mobile phones to indicate the international access code.

Numbering and Overlay Considerations

As of the latest ENACOM updates, no overlay code has been assigned to the 3584 area. The numbering capacity is sufficient for the current population density. However, if you are experiencing issues with call completion, it is recommended to verify the number length and formatting, as well as any carrier-specific requirements for VoIP or mobile services.
