📍 Geographic Location of Chihuahua
Geographic Coverage and Administrative Jurisdiction
The area code 625 is a geographic National Destination Code (NDC) assigned to the northwestern region of the state of Chihuahua, Mexico. This code serves a cluster of municipalities, with the primary urban center being Ciudad Cuauhtémoc, the state's third-largest city. The coverage area extends to surrounding communities such as Anáhuac, Colonia Anáhuac, and rural localities within the municipalities of Cuauhtémoc, Cusihuiriachi, and parts of Riva Palacio. Administratively, these areas fall under the jurisdiction of the state government of Chihuahua and are part of the country's northern border economic zone.
Dialing Formats and Caller Instructions
For callers within Mexico, dialing a number in the 625 area code requires the national long-distance prefix 01, followed by the area code and the seven-digit local number. For example, to reach a landline in Ciudad Cuauhtémoc, you would dial: 01 625 123 4567. However, since 2019, Mexico has implemented the elimination of the long-distance prefix for calls to geographic numbers; in practice, dialing 625 123 4567 from any Mexican phone (mobile or fixed) also works, as the network automatically routes the call. For international callers, the format is: +52 625 123 4567. The plus sign represents the international access code, and 52 is Mexico's country calling code. It is essential to drop the leading '0' when dialing from abroad.
Overlay and Numbering Considerations
Currently, the 625 area code does not have an overlay. However, due to growing demand for telecommunication services in the region, the Federal Telecommunications Institute (IFT) has implemented number pooling and conservation measures to extend the life of the existing code. As of now, all numbers within 625 are seven digits long, and the area code is used exclusively for fixed-line services, including PSTN and some VoIP providers that offer local presence. Mobile numbers in the region are assigned under the non-geographic mobile codes (e.g., 614, 626, etc.) and are not tied to a specific area code.
Practical Information for Callers
- Local calls: Within the same area code, you may dial the seven-digit number directly without the area code, but it is safer to include the area code to avoid misrouting.
- Caller identification: When receiving calls from this region, the caller ID will display +52 625 followed by the seven-digit number.
- Emergency services: In Mexico, the universal emergency number is 911, which is accessible from any phone, regardless of area code.
- Business and tourism: Ciudad Cuauhtémoc is known for its Mennonite communities and apple orchards; many businesses in the region use 625 numbers for customer service.
