Area Code 2940 – Ingeniero Jacobacci, Río Negro

Overview of Area Code 2940

Area code 2940 is a geographic National Destination Code (NDC) assigned to the region surrounding Ingeniero Jacobacci in the province of Río Negro, Argentina. This area code serves the Andean-Patagonian corridor, including localities such as Ingeniero Jacobacci, Comallo, and smaller rural settlements along the Ruta Nacional 23. The region is characterized by its remote, sparsely populated terrain, and the numbering plan follows the standard Argentine fixed-line format.

Dialing Formats

For local calls within the same area code, subscribers in Argentina typically dial the 7-digit subscriber number directly (without the area code). However, for calls from other regions within Argentina, the full national format is used:

• National (domestic) dialing: 0 2940 XXX XXX (where the leading 0 is the national trunk prefix, 2940 is the area code, and the subscriber number is 7 digits).
• International dialing from abroad: +54 2940 XXX XXX (replace the leading 0 with the country code +54).

Example: If the local subscriber number is 456 7890, a caller from Buenos Aires would dial 0 2940 456 7890, while a caller from the United States would dial +54 2940 456 7890.

Geographic Coverage and Administrative Jurisdiction

The 2940 area code covers the Pilcaniyeu Department and parts of the Ñorquincó Department in Río Negro Province. Key towns served include Ingeniero Jacobacci (the main urban center), Comallo, and Anecón Grande. The region is a gateway to the Patagonian steppe and is known for its railway history and sheep farming. The area code is administered under Argentina's national numbering plan, overseen by the Ente Nacional de Comunicaciones (ENACOM).

Caller Instructions

For local callers within the 2940 area, dialing the 7-digit number is sufficient. For callers from other Argentine provinces, always include the trunk prefix 0 followed by the area code. For international callers, use the country code +54 and omit the trunk prefix. Note that mobile numbers in Argentina are not prefixed with 2940; they use the mobile-specific codes starting with 11, 22, 23, etc., and are dialed differently. If you are calling a fixed line in this region from a mobile phone, you must still dial the full national format including the area code.

Overlay and Numbering Considerations

As of the latest ENACOM updates, there is no overlay code for 2940; the area code is unique to this geographic region. However, due to the low population density, number exhaustion is not a current concern. The subscriber numbers are typically 7 digits long, and the total number of digits for an international call is 12 (including the +54 country code). Always verify the current dialing procedures with your telecom provider, as routing may vary for VoIP services.
