📍 Geographic Location of Petatlan/San Jeronimito, GRO
Geographic Coverage and Administrative Jurisdiction
The +52 758 country calling code and area code combination corresponds to a geographic numbering plan area within the state of Guerrero (GRO), Mexico. Specifically, this National Destination Code (NDC) serves the municipalities and localities around Petatlán and San Jeronimito, including adjacent rural and coastal communities. The region is part of the Costa Grande of Guerrero, with Petatlán serving as the primary administrative and commercial hub. The numbering area is regulated by the Instituto Federal de Telecomunicaciones (IFT) under Mexico's national numbering plan, which follows ITU-T E.164 recommendations.
Dialing Formats and Caller Instructions
For callers within Mexico, the domestic long-distance format requires dialing the prefix 01 before the area code and subscriber number. For example, to call a landline in Petatlán from Mexico City, you would dial: 01 758 XXX XXXX. For international callers, the format is +52 758 XXX XXXX (or 011 52 758 XXX XXXX from the US/Canada). The subscriber number is seven digits long, making the total national significant number (NSN) ten digits (excluding the trunk prefix).
Overlay Considerations and Numbering Resources
Currently, there is no overlay code for the 758 area; the region retains a single NDC. However, as with many Mexican geographic areas, number portability allows subscribers to retain their numbers when switching between fixed-line operators, but the geographic indicator remains tied to the original location. The area code is assigned to fixed-line services (PSTN), including residential and business lines, and is not used for mobile services, which use dedicated non-geographic mobile prefixes (e.g., 044, 045, or 1 followed by the mobile number).
Practical Guidance for Local and Foreign Callers
When dialing locally within the same area code, callers may omit the area code and dial only the seven-digit local number. However, for clarity and to avoid misdialing, it is recommended to use the full national format. For foreign callers, it is essential to replace the leading zero of the domestic trunk prefix with the country code +52. Also, note that calls to this geographic region are subject to standard international and domestic tariffs, which vary by carrier. For VoIP users, ensure that your service provider supports dialing to Mexican geographic numbers and that you include the country code.
