Area Code 2964 – Río Grande, Tierra del Fuego

Overview of Area Code 2964

Area code 2964 is a geographic National Destination Code (NDC) assigned to the city of Río Grande and its surrounding localities within the province of Tierra del Fuego, Antarctica, and South Atlantic Islands in southern Argentina. This region is part of the Argentine Patagonia, and the code serves a sparsely populated but economically significant area, known for its industrial parks and proximity to the Atlantic coast.

Geographic Coverage and Administration

The 2964 area code covers the northern part of the Isla Grande de Tierra del Fuego, including the urban center of Río Grande and nearby rural settlements. It is administered under the Argentine national numbering plan, which follows ITU-T E.164 recommendations. The province's other main city, Ushuaia, uses a different area code (2901), so callers must be mindful of the distinction.

Dialing Formats

For local calls within Río Grande, subscribers typically dial the seven-digit subscriber number without the area code. However, for all calls from outside the area code (including from other Argentine provinces or from abroad), the full national or international format is required.

• National dialing (from within Argentina, outside 2964): Dial 0 + 2964 + subscriber number. The leading '0' is the trunk prefix.
• International dialing (from outside Argentina): Dial the Argentine country code +54, then the area code 2964 (without the trunk prefix '0'), followed by the seven-digit subscriber number. For example, a call to a Río Grande landline might be dialed as +54 2964 1234567.

Overlay and Numbering Considerations

As of the latest ITU-T and ENACOM (Ente Nacional de Comunicaciones) updates, there is no overlay code for 2964. The area code is not subject to number portability for geographic numbers in the same way as mobile numbers, but fixed-line portability is available under national regulations. Subscriber numbers within 2964 are seven digits long, and the total length of a national significant number (NSN) for Argentina is ten digits (including the area code but excluding the trunk prefix).

Caller Instructions

For local callers within Río Grande, simply dial the seven-digit number. For callers from other Argentine cities, include the trunk prefix '0' and the area code. For international callers, always use the plus sign (+) or the appropriate international access code, followed by 54 and 2964. Remember that when calling from a mobile phone in Argentina, you may need to include the '0' and area code even for local calls, depending on your carrier's settings.
