Overview of Area Code 659
Area code 659 is a geographic numbering plan area (NPA) in Mexico, assigned to the state of Chihuahua. It serves the southwestern region of the state, with its primary hub in the city of Guachochi. The coverage area includes the municipalities of Guachochi, Balleza, and Nonoava, among others. This region is characterized by the Sierra Tarahumara, a mountainous area known for its Copper Canyon, and is home to significant indigenous communities (Rarámuri).
Dialing Formats
When dialing a number within area code 659 from within Mexico, the national long-distance format is used: 01 659 XXX XX XX. The prefix '01' is the national trunk prefix, followed by the area code and the seven-digit local number. For callers from outside Mexico, the international format is +52 659 XXX XX XX. The country code for Mexico is +52, and the area code is dialed without the leading '0'.
Local and International Calling Instructions
- Local calls within the same area code: In Mexico, local calls are generally dialed using only the seven-digit number (XXX XX XX). However, due to the rural nature of this region, some fixed-line operators may require the full national format even for local calls. It is advisable to check with your service provider.
- National long-distance calls (from other area codes in Mexico): Dial 01 659 XXX XX XX.
- International calls from abroad: Dial your country's exit code (e.g., 011 from the US/Canada), then 52, then 659, then the seven-digit number. Example: +52 659 123 45 67.
Geographic Coverage and Administration
The 659 area code is part of the Mexican numbering plan administered by the Instituto Federal de Telecomunicaciones (IFT). It is assigned to the geographic region of Chihuahua, which is a large northern state bordering the United States. The area code covers a predominantly rural and mountainous zone, with limited telecommunications infrastructure compared to urban centers like Ciudad Juárez or Chihuahua City. The main economic activities include forestry, agriculture, and tourism related to the Copper Canyon.
Overlay and Numbering Considerations
As of the latest IFT updates, there is no overlay area code for 659; it is the sole area code for this region. However, due to the increasing demand for numbers, the IFT has implemented number pooling and other conservation measures. For callers, it is important to note that the seven-digit local number is not portable across geographic area codes; if a subscriber moves to a different area code, they must obtain a new number.
Practical Tips for Callers
When calling a number in the 659 area code, always ensure you have the correct seven-digit number. For international callers, be mindful of time zones: Chihuahua is in the Mountain Time Zone (UTC-7) and observes daylight saving time from the first Sunday in April to the last Sunday in October. For emergency services, dial 911 from any phone in Mexico.
