📍 Geographic Location of Guerrero
Overview of Area Code 736
Area code 736 is a geographic dialing code assigned to the state of Guerrero in Mexico, specifically covering the northern and central portions of the state. It is part of the national numbering plan administered by the Federal Telecommunications Institute (IFT) under ITU-T E.164 standards. The code serves a mix of urban and rural communities, with the principal city being Chilpancingo de los Bravo, the state capital. Other notable localities include Tixtla de Guerrero, Zumpango del Río, and Eduardo Neri (Zumpango). The region is characterized by mountainous terrain and a dispersed population, which influences the deployment of both fixed-line and mobile infrastructure.
Geographic Coverage and Jurisdiction
The 736 area code covers a significant portion of the state of Guerrero, excluding coastal areas that use other codes such as 744 (Acapulco) or 747 (Ixtapa-Zihuatanejo). The jurisdiction falls under the state of Guerrero, with municipal authorities overseeing local services. The numbering area is not overlaid with another area code, meaning that local calls within the region require only the seven-digit local number, while calls from outside the region require the full national format.
Dialing Formats and Procedures
For local calls within area code 736, callers can dial the seven-digit subscriber number directly. However, for calls originating from other area codes within Mexico, the national long-distance format must be used: 01 736 XXX XX XX. For international callers, the format is +52 736 XXX XX XX (or 011 52 736 XXX XX XX when dialing from the United States or Canada). It is important to note that the Mexican numbering plan requires the prefix '01' for national long-distance calls, which is often omitted when dialing from mobile phones but is essential for landline-to-landline calls.
Telecom Infrastructure and Services
The region is served by major Mexican carriers including Telmex, Telcel, Movistar, and AT&T Mexico, as well as various cable operators offering VoIP services. Fixed-line penetration is moderate, with a growing reliance on mobile services, especially in rural areas. Number portability is available, allowing subscribers to retain their numbers when switching carriers, but the geographic nature of the code means that the number remains associated with the 736 area. Emergency services, such as 911, are accessible throughout the region, and the area code is fully integrated into the national emergency response system.
Practical Guidance for Callers
When calling a number in the 736 area from abroad, always replace the leading '0' of the national prefix with the country code for Mexico (+52). For example, to call a Chilpancingo landline, dial +52 736 123 45 67. If you are within Mexico but outside the 736 area, dial 01 736 123 45 67. For mobile numbers in the same area, the dialing format is identical, as mobile numbers also use the 736 prefix when assigned to this region. Always verify the number length: local numbers are seven digits, and the complete international format includes the country code, area code, and seven-digit number.
