Area Code 67 – Coyhaique, Aisén

Geographic Coverage and Administrative Jurisdiction

The +56 67 country calling code and area code combination corresponds to a geographic numbering plan area within the Republic of Chile. Specifically, the 67 prefix is assigned to the Aisén del General Carlos Ibáñez del Campo Region (commonly referred to as the Aisén Region or Region of Aysén), which is located in the southern part of Chilean Patagonia. The primary administrative center and largest city served by this code is Coyhaique, the regional capital. Other significant localities within this numbering area include Puerto Aysén, the principal port city, as well as smaller towns such as Balmaceda, Chile Chico, Cochrane, and Villa O'Higgins. The region is characterized by its remote, rugged geography, including fjords, glaciers, and vast tracts of pristine wilderness, which influences the deployment of telecommunications infrastructure.

Dialing Formats and Caller Instructions

For callers placing a domestic long-distance call to a fixed-line subscriber within Chile, the standard dialing sequence is the national trunk prefix 0, followed by the area code 67, and then the subscriber's seven-digit local number. For example, to reach a landline in Coyhaique with a local number 2 345 678, a caller from Santiago would dial 0 67 2 345 678. For callers dialing from outside Chile, the international access code of the originating country must be used, followed by Chile's country code 56, the area code 67 (without the leading trunk prefix), and the seven-digit local number. Thus, an international caller would dial +56 67 2 345 678. It is important to note that the area code is an integral part of the national numbering plan and must always be dialed when calling from outside the local area, even if the destination is within the same region.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan updates, the 67 area code does not have an overlay code; it serves as the sole geographic area code for the Aisén Region. The subscriber numbers within this area are seven digits in length, and the total number of digits for a national significant number (NSN) is nine, including the area code. The Chilean telecommunications regulator, Subtel (Subsecretaría de Telecomunicaciones), manages the allocation of numbering resources. While the region's low population density means that number exhaustion is not an immediate concern, Subtel has implemented number portability across the country, allowing subscribers to retain their numbers when changing service providers, provided they remain within the same geographic area.

Practical Guidance for Callers

For local callers within the 67 area code, dialing the seven-digit subscriber number directly is sufficient, without the trunk prefix or area code. For example, a caller in Coyhaique would simply dial 2 345 678. Foreign callers should be aware that Chilean fixed-line numbers are not mobile numbers; mobile numbers in Chile begin with the digit 9 and are non-geographic. Additionally, when dialing from a mobile phone within Chile, the trunk prefix 0 is often replaced by the carrier's mobile access code, but for simplicity, using the standard 0 67 format is recommended. For international callers, it is advisable to check with their service provider for any specific dialing requirements or restrictions, especially for calls to remote regions.
