Area Code 2357 – Carlos Tejedor, Buenos Aires

Overview of Area Code 2357

Area code 2357 is a geographic National Destination Code (NDC) assigned to the city of Carlos Tejedor and its surrounding rural districts in the northwestern part of Buenos Aires Province, Argentina. This region is part of the Argentine numbering plan administered under ITU-T E.164, with the country calling code +54. The code covers the administrative partido of Carlos Tejedor, including the principal urban center and smaller localities such as Tres Algarrobos, Curarú, and Ingeniero Williams.

Dialing Formats

When calling a fixed-line number in Carlos Tejedor from within Argentina, the subscriber number is seven digits long, and the full national significant number (NSN) consists of the area code plus the subscriber number: 2357-XXXXXXX. To call from a domestic phone, dial 0 followed by the area code and the local number: 0-2357-XXXXXXX. For international callers, the Argentine country code (+54) replaces the trunk prefix, so the format becomes +54 2357 XXXXXXX. It is important to note that the leading '0' is only used for domestic calls and must be omitted when dialing from abroad.

Geographic Coverage and Administrative Context

Carlos Tejedor is located approximately 450 kilometers west of Buenos Aires city, in the Pampas region. The area code serves the entire Carlos Tejedor Partido, which is a rural agricultural zone known for grain and cattle production. The region is characterized by small towns and scattered farming communities, and the fixed-line infrastructure is provided by the national incumbent operator, Telefónica de Argentina (Movistar), along with other licensed local carriers. As a geographic code, 2357 is tied to the physical location of the line, and calls are routed through the PSTN based on the destination's central office.

Caller Instructions

For local callers within the same area code, it is possible to dial only the seven-digit subscriber number, depending on the local dialing plan. However, for calls from other Argentine cities or from abroad, the full national or international format must be used. There are no overlay codes currently assigned to this region, so the area code remains unique for the geographic area. When calling from a mobile phone in Argentina, the same trunk prefix '0' is used, but the call may be subject to different tariffs depending on the operator.

Regulatory and Technical Notes

Argentina's numbering plan is regulated by ENACOM (Ente Nacional de Comunicaciones). Geographic area codes are assigned based on the location of the telephone exchange, and number portability is available for fixed lines, allowing users to retain their numbers when changing providers within the same geographic area. For international calls to Carlos Tejedor, ensure you have the correct country code (+54) and omit the trunk prefix '0'. The number length after the country code is 10 digits (area code + subscriber number), which is standard for Argentine fixed lines.
