Area Code 767 – Guerrero

Overview of Area Code 767

Area code 767 is a geographic dialing code assigned to the northern region of the state of Guerrero, Mexico. It serves as the National Destination Code (NDC) for a cluster of municipalities located along the Pacific coast and inland areas, with the primary urban center being Ciudad Altamirano. Other notable localities covered by this code include Coyuca de Catalán, Tlapehuala, Arcelia, San Jerónimo, and Ajuchitlán del Progreso. The region is characterized by a mix of agricultural communities, small commercial hubs, and scenic river valleys, making it an important communication corridor between the state capital, Chilpancingo, and the border with the state of Michoacán.

Geographic Coverage and Jurisdiction

Area code 767 falls under the administrative jurisdiction of the Mexican Federal Telecommunications Institute (IFT) and is allocated for fixed-line (PSTN) services, including traditional copper lines, cable telephony, and fixed wireless access. The code covers a predominantly rural and semi-urban area, with Ciudad Altamirano serving as the commercial and administrative center. Other municipalities within this code include Pungarabato, which is where Ciudad Altamirano is located, as well as Zirándaro, Cutzamala de Pinzón, and portions of the Tierra Caliente region. The geographic boundaries of the code are defined by the local exchange areas, and calls between different localities within the same area code are typically treated as local calls, subject to the applicable tariff.

Dialing Formats and Instructions

For callers within Mexico, dialing a number in area code 767 requires the national long-distance prefix '01' followed by the area code and the seven-digit local number. For example, to call a fixed line in Ciudad Altamirano from Mexico City, you would dial: 01 767 123 4567. For international callers, the format is the Mexican country code (+52), followed by the area code and the local number, without the '01' prefix. Thus, from the United States or any other country, you would dial: +52 767 123 4567. It is important to note that the area code is an integral part of the national numbering plan and must be dialed even for calls originating from within the same geographic region, unless the network supports seven-digit local dialing, which is uncommon in this area.

Overlay and Numbering Considerations

As of the latest IFT updates, area code 767 does not have an overlay code, meaning that it is the sole area code for its geographic region. However, due to the growth of mobile and VoIP services, some numbers may appear with this prefix but are actually assigned to mobile operators or VoIP providers. These numbers are non-geographic in nature and are not tied to the physical location of the caller or the callee. For businesses and residents, it is essential to verify the type of service associated with a number, as call rates may vary. For instance, calls to mobile numbers in Mexico are typically charged at a higher rate than fixed-line calls, even if the mobile number uses a geographic area code. This is a result of the mobile numbering scheme, which allows mobile numbers to have the same NDC as fixed lines, but with different tariff structures.

Practical Information for Callers

When placing a call to area code 767, ensure that you have the correct seven-digit local number. Local numbers in this area may start with digits 1 through 9, but the first digit cannot be 0 or 1. If you are unsure about the number, consult a directory or contact the local operator. For emergency services, always dial 911 from any phone in Mexico. For other services, such as directory assistance, dial 040 from within Mexico. Given the rural nature of the region, some areas may have limited cellular coverage, so it is advisable to have alternative communication methods when traveling to remote locations. Overall, area code 767 is a vital part of Guerrero's telecommunications infrastructure, connecting its residents and businesses to the rest of Mexico and the world.
