📍 Geographic Location of Guerrero
Geographic Overview
The area code 747 is a geographic National Destination Code (NDC) assigned to the state of Guerrero, Mexico, under the international country calling code +52. This code serves the central and northern regions of Guerrero, including municipalities such as Chilpancingo de los Bravo (the state capital), Tixtla de Guerrero, Zumpango del Río, and surrounding communities. It is important to note that the 747 area code is an overlay for the previously assigned 747 region, which historically used the 747 code for Chilpancingo and its environs. As of the latest numbering plan updates, 747 is the sole geographic code for this area, replacing the older 747 and 747 codes.
Dialing Formats
For callers within Mexico, local calls to numbers in the 747 area code require dialing the 10-digit national number: 747 XXX XXXX. For international callers, the full international format must be used: +52 747 XXX XXXX. When dialing from a mobile phone within Mexico, it is also necessary to include the national trunk prefix '1' before the area code when calling a landline from a mobile, but this practice has been simplified; currently, all national calls use 10-digit dialing without the trunk prefix. For example, to call a landline in Chilpancingo from abroad, you would dial +52 747 123 4567.
Geographic Coverage and Administration
The 747 area code falls under the jurisdiction of the Secretaría de Infraestructura, Comunicaciones y Transportes (SICT) and the Instituto Federal de Telecomunicaciones (IFT), which regulate Mexico's numbering resources. The region is served by major telecom operators, including Telmex, Telcel, Movistar, and AT&T Mexico, providing both fixed and mobile services. The area is characterized by a mix of urban and rural communities, with economic activities ranging from government services and education to agriculture and tourism.
Caller Instructions
- Local callers (within Mexico): Dial the 10-digit number: 747 XXX XXXX.
- International callers: Dial your country's exit code, then 52, then 747, then the 7-digit local number: +52 747 XXX XXXX.
- Mobile to landline: In Mexico, all calls are now dialed as 10-digit numbers; no additional prefix is required.
Since 747 is a geographic code, the number is tied to a physical location, and calls are routed through the PSTN. However, with the rise of VoIP and number portability, some numbers may be served by IP-based networks, but the geographic association remains for regulatory and emergency services purposes.
