Area Code 2346 – Chivilcoy, Buenos Aires

Overview of Area Code 2346

Area code 2346 is a geographic National Destination Code (NDC) assigned to the city of Chivilcoy and its surrounding rural districts in the province of Buenos Aires, Argentina. This code is part of the national numbering plan administered by the Ente Nacional de Comunicaciones (ENACOM), following ITU-T E.164 recommendations. The region falls under the Buenos Aires Interior numbering area, distinct from the metropolitan area codes of Buenos Aires City (11) and Greater Buenos Aires (e.g., 11 for the northern and southern zones).

Geographic Coverage and Jurisdiction

The 2346 code covers the Chivilcoy Partido, which includes the city of Chivilcoy (the administrative seat) and smaller localities such as Moquehuá, Gorostiaga, and La Rica. Chivilcoy is located approximately 160 kilometers west of Buenos Aires City, in the agricultural heartland of the Pampas. The area is served by both fixed-line PSTN infrastructure and VoIP services, with incumbent provider Telefónica de Argentina operating under the Movistar brand, alongside alternative carriers offering local and long-distance services.

Dialing Formats and Instructions

For callers within Argentina, the national trunk prefix 0 is used before the area code when dialing from outside the local area. The complete national significant number (NSN) for a fixed-line subscriber in Chivilcoy is 0-2346-XXXXXX, where X represents the six-digit local subscriber number. For example, to call a local number 456789 from Buenos Aires City, you would dial 0 2346 456789.

For international callers, the Argentine country code +54 is used, followed by the area code without the leading zero. Thus, the same number would be dialed as +54 2346 456789. When dialing within the same area code, local calls can be made using only the six-digit subscriber number (e.g., 456789).

Overlay and Numbering Considerations

Currently, there is no overlay code for 2346; the area code serves exclusively the Chivilcoy region. However, as part of ENACOM's ongoing efforts to expand numbering resources, future overlays may be introduced, but as of now, ten-digit dialing (including the area code) is required for all calls made from outside the local area. Mobile numbers in Argentina are not tied to geographic areas and use the prefix 9 after the country code when dialed internationally, but fixed-line calls to 2346 follow the standard geographic routing.

Practical Guidance for Callers

For local callers within Chivilcoy, simply dial the six-digit number. For callers elsewhere in Argentina, always include the trunk prefix 0 and the area code 2346. For international callers, remember to drop the trunk prefix and use +54 2346. This ensures proper routing through the PSTN and avoids misdialing. Businesses in the region often list their numbers in international format to facilitate global communication.
