Area Code 2355 – Lincoln, Buenos Aires

Overview of Area Code 2355

Area code 2355 is a geographic National Destination Code (NDC) assigned to the western part of Buenos Aires Province, Argentina. It serves the city of Lincoln and its surrounding rural districts, including towns such as Roberts, Triunvirato, and Pasteur. This region is part of the Argentine Pampas, an agricultural heartland known for grain and cattle production.

Coverage and Administration

The code falls under the jurisdiction of the Ente Nacional de Comunicaciones (ENACOM), Argentina's national telecommunications regulator. It covers a sparsely populated area with a mix of small urban centers and farming communities. The administrative center is Lincoln, located approximately 350 kilometers west of Buenos Aires city.

Dialing Formats

For local calls within the same area code, subscribers dial the seven-digit subscriber number directly. For calls from other Argentine provinces or mobile networks, the full national format is used:

• National dialing: 0 2355 42XXXX (where 42XXXX is the local number)
• International dialing: +54 2355 42XXXX

Example: To call a business in Lincoln from abroad, you would dial +54 2355 42 1234. From a mobile phone in Buenos Aires, you would dial 0 2355 42 1234.

Overlay and Numbering Changes

As of 2024, area code 2355 does not have an overlay. However, ENACOM has implemented a national plan to unify mobile and fixed-line numbering, which may affect dialing procedures in the future. Currently, fixed-line numbers in this region have seven digits after the area code, while mobile numbers begin with 15 or 11 and are not tied to geographic boundaries.

Caller Instructions

For local callers: If you are within the 2355 area, simply dial the seven-digit number. For national callers: Always include the trunk prefix 0 followed by the area code. For international callers: Replace the trunk prefix with Argentina's country code +54 and omit the leading zero. Ensure you have the correct international exit code for your country (e.g., 011 from the US, 00 from most European countries).

Telecom Infrastructure

Both fixed and mobile services are available in the region. Major Argentine carriers such as Telefónica (Movistar), Telecom (Personal), and Claro operate in the area, providing PSTN, ADSL, and fiber-optic broadband services. VoIP services are also available, but emergency calls (e.g., 911) require a physical line or registered address.
