Telephone numbers in Chile
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 among land-line, 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, area code and an extra 2 were added at the beginning of the number, or between the area code and 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. Total number portability 
Total number portability exists in Chile, so users can freely move from one service provider to another without losing their number, regardless of connection technology, whether land-line, mobile or VoIP. Therefore, a number beginning with "8" or "9" no longer denotes that it is a mobile phone 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
