Telephone numbers in Chile

Telephone numbers in Chile is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Telephone numbers in Chile rather than just read about it. In short: The following telephone numbers in Chile are geographic area codes for all national and international calls terminating in Chile. Geographic area codes No geographic area codes exist in Chile; all calls within Chile are considered local calls.

Key takeaways

Telephone numbers in Chile belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Telephone numbers in Chile to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Telephone numbers in Chile from memory before moving on to harder problems.

Reference excerpt

The following telephone numbers in Chile are geographic area codes for all national and international calls terminating in Chile.

Geographic area codes No geographic area codes exist in Chile; all calls within Chile are considered local calls. All numbers contain 9 digits, and there is no difference between landline, mobile, and VoIP

Transition to area code deprecation In 2012 and 2013, land lines were renumbered, with an additional digit (2) prepended. The change was rolled out gradually by area code; first in Santiago (Region Metropolitana) and Arica in late 2012, then throughout all remaining regions between March and July 2013. During that transitional period, when calling a landline, the area code and an extra 2 were added at the beginning of the number, or between the area code and the number. E.g. a formerly seven-digit Santiago number (02) XXX XXXX became 22X XXX XXX, and a formerly six-digit Punta Arenas number (061) YYY YYY became 612 YYY YYY. The process was completed in September 2016.

Number portability Number portability is available across the entire telephone network in Chile, so users can freely move from one service provider to another without changing their telephone number, regardless of connection technology, whether landline, mobile, or VoIP. Therefore, a number beginning with "8" or "9" no longer denotes that it is a mobile telephone number.

Special services There is a group of special numbers for public services, and they are in the format 1XY. The most important ones are:

130 Forest fires (Incendios forestales) 131 Ambulance (SAMU) 132 Firefighters (Bomberos) 133 Police Emergency (Emergencias Policiales) 134 Investigaciones 135 Drug usage prevention hot line (Fono drogas) 136 Mountain Rescue (Cuerpo de Socorro Andino) 137 Sea Rescue (Rescate Marítimo de la Armada) 139 Police Information (Informaciones Policiales) 147 Child abuse prevention (Fono niños) 149 Family Violence (Fono familia)

Long-distance carriers In Chile, it is necessary to choose the carrier for international long-distance calls every time, and therefore, to obtain the best rate for any destination. Long-distance carriers have a prefix that must be dialed when calling long distance: XXX + 0 + country code + area + phone The carrier codes are:

110 Claro Chile 111 VTR Chile 112 Convergia Chile 113 Transam 114 E-Newcarrier.com Chile 115 Empresa de Telecomunicaciones Netonone 116 Heilsberg 119 Concert Chile 120 Globus 121 Telefónica del Sur 122 Gtd Manquehue 123 Entel Larga Distancia 124 GSP Chile 125 Equant Chile 127 Sur Telecomunicaciones 151 Astro 153 STEL-CHILE S.A 154 MiCarrier Telecomunicaciones 155 Claro Chile 158 Fibersat 169 Carrier 169 170 Impsat Chile 170 Global Crossing 171 Claro Chile 176 NetChile 177 Empresa de Transporte de Señales 180 Hogar de Cristo 181 Movistar 188 Telefónica CTC

Mobile telephone numbers Mobile telephone numbers do not have a specific starting digit.

Worked examples

Example 1 — a first encounter with Telephone numbers in Chile

Start with the simplest possible case. Write down what Telephone numbers in Chile claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Telephone numbers in Chile before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Telephone numbers in Chile ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Telephone numbers in Chile

In research: Telephone numbers in Chile appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Telephone numbers in Chile in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Telephone numbers in Chile is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chile communications-related lists, Telecommunications in Chile, Telephone numbers by country, so understanding it makes those chapters shorter.
In everyday life: Look for Telephone numbers in Chile outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
