📍 Geographic Location of Comodoro Rivadavia, Chubut
Overview
The Argentine national destination code (NDC) 2976 is a geographic area code assigned to the city of Comodoro Rivadavia and its surrounding localities in the province of Chubut, within the Patagonian region. This code is part of the national numbering plan administered by the Ente Nacional de Comunicaciones (ENACOM), following ITU-T E.164 recommendations. The area code 2976 is used for fixed-line (PSTN) services, and it is also employed for some mobile numbers that have been ported to geographic ranges, though mobile numbers typically use non-geographic prefixes starting with 11, 22, or 33.
Geographic Coverage
The 2976 code covers the urban and peri-urban zones of Comodoro Rivadavia, the largest city in Chubut, as well as nearby towns such as Rada Tilly, Caleta Córdova, and other localities within the Escalante Department. The region is a major hub for the oil and gas industry, with a population of over 180,000 in the metropolitan area. The code also serves some rural areas and smaller communities that rely on fixed-line connections.
Dialing Formats
For local calls within the same area code, subscribers dial the 7-digit subscriber number directly, without the prefix or the area code. For example, to call a local number 456-7890, you would dial 456-7890.
For national long-distance calls from other Argentine provinces, you must dial the national trunk prefix 0, followed by the area code 2976, and then the subscriber number. For instance, from Buenos Aires, you would dial 0-2976-456-7890.
For international calls from abroad, you need to dial the Argentine country code +54, then the area code without the leading zero, and then the subscriber number. Thus, a caller from the United States would dial +54-2976-456-7890.
Overlays and Numbering
As of now, there is no overlay plan for the 2976 area code, meaning that the area code is unique for the region. However, due to the growth of telecommunications services, ENACOM periodically reviews numbering resources. The subscriber numbers in this area are 7 digits long, and the total length of a national significant number (NSN) is 10 digits, including the area code but excluding the trunk prefix.
Caller Instructions
- Local callers: Dial the 7-digit subscriber number only.
- National callers: Dial 0 + area code + subscriber number.
- International callers: Dial your country's exit code (e.g., 011 from the US) + 54 + area code (without the leading zero) + subscriber number.
When calling from a mobile phone in Argentina, it is common to omit the trunk prefix '0' and dial the area code directly, as mobile networks automatically handle the routing. However, for clarity, the standard format is still recommended.
