Area Code 211 – Santiago, Metropolitan Region

Overview of Area Code 211 (Chile)

Area code 211 is a geographic National Destination Code (NDC) assigned to the Santiago Metropolitan Region of Chile, specifically serving the national capital, Santiago, and its surrounding urban and suburban areas. As part of the Chilean numbering plan, this code is used for fixed-line (PSTN) services, including traditional copper lines, cable telephony, and fixed VoIP services that are allocated a geographic number. The code falls within the broader 2XX range that covers the Santiago Metropolitan Region, which is the most densely populated area of the country.

Geographic Coverage and Administrative Jurisdiction

The 211 code covers the province of Santiago and the entire Metropolitan Region, which includes communes such as Providencia, Las Condes, Ñuñoa, Maipú, and Puente Alto. This region is the political, financial, and cultural hub of Chile. The code is administered by the Subsecretaría de Telecomunicaciones (SUBTEL), the national regulatory authority, and is allocated to various incumbent and competitive local exchange carriers.

Dialing Formats and Caller Instructions

• Local calls (within Chile): To call a number within the same area code, dial the 8-digit subscriber number directly. For example, if the local number is 211 2345, dial 211 2345.
• National long-distance calls (from other Chilean area codes): Dial the trunk prefix 0, then the area code 2 (the NDC for Santiago), followed by the 8-digit subscriber number. For instance, to call a number in Santiago from Valparaíso, dial 0 2 211 2345.
• International calls (from outside Chile): Dial the international access code (e.g., 00 or +), then Chile’s country code 56, then the area code 2 (without the leading 0), followed by the subscriber number. For example, from the United States, dial 011 56 2 211 2345 or +56 2 211 2345.

Numbering Structure and Overlay Considerations

Chilean fixed-line numbers in Santiago have a total length of 9 digits when including the country code and the NDC (i.e., +56 2 XXXX XXXX). The subscriber number is 8 digits long. Currently, there is no overlay code in Santiago; the entire Metropolitan Region uses the single NDC 2. However, due to increasing demand, SUBTEL has implemented number pooling and reallocation measures to ensure sufficient numbering resources. Area code 211 is a specific block within the 2XX range, and its assignment does not affect the dialing plan.

Technical and Regulatory Notes

All geographic numbers in Chile are portable, meaning subscribers can switch service providers while retaining their number. However, number portability does not change the geographic significance of the code. Calls to 211 numbers are typically charged based on the caller’s location and tariff plan. For international callers, rates vary by carrier. Emergency services (e.g., 131 for medical, 132 for fire) are accessible nationwide without the area code.
