Overview of Area Code 2901
Area code 2901 is a geographic National Destination Code (NDC) assigned to the city of Ushuaia, the capital of the province of Tierra del Fuego, Antártida e Islas del Atlántico Sur in Argentina. This code serves the southernmost city in the world and its immediate surroundings, including the tourist hub of the Beagle Channel and the nearby town of Tolhuin (though Tolhuin primarily uses 2901 as well). The region is known for its dramatic Patagonian landscapes, Tierra del Fuego National Park, and as a gateway to Antarctica.
Geographic Coverage and Jurisdiction
The 2901 NDC covers the eastern part of Isla Grande de Tierra del Fuego, encompassing the administrative departments of Ushuaia and Río Grande (the latter uses 2964, but 2901 is specifically for Ushuaia and its rural areas). The province is an autonomous territory with its own government, and telecommunication services are regulated by the Ente Nacional de Comunicaciones (ENACOM).
Dialing Formats
When calling a fixed-line number in Ushuaia, the local number has 7 digits after the area code. The complete international format is +54 2901 XXX XXXX.
- Domestic calls within Argentina (from other provinces): Dial 0 2901 XXX XXXX. The leading '0' is the national trunk prefix.
- Local calls within Ushuaia: You can dial the 7-digit subscriber number directly, without the area code (e.g., XXX XXXX).

Overlays and Numbering
Currently, there is no overlay code for Ushuaia; 2901 is the sole geographic area code for the city. However, as with all Argentine fixed-line services, number portability is available for fixed lines, allowing subscribers to retain their numbers when changing providers within the same geographic area.
Caller Instructions
For local callers within Ushuaia, simply dial the 7-digit number. For callers elsewhere in Argentina, always include the national trunk prefix '0' followed by the area code. For international callers, remember to replace the '0' with the country code '54' and drop the trunk prefix. Always verify the current dialing rules, as ENACOM may update numbering plans.
