Area Code 595 – Estado de Mexico

Geographic Overview and Coverage

Area code 595 is a geographic numbering plan area within the Mexican national numbering framework, administered under the ITU-T E.164 country code +52. It serves a defined region in the State of Mexico (Estado de Mexico), one of the 32 federal entities of Mexico. The code covers municipalities and localities in the central part of the state, including the city of Tejupilco de Hidalgo and surrounding communities such as Amatepec, Tlatlaya, and Luvianos. These areas are situated in the southern mountainous region of the State of Mexico, characterized by a mix of urban centers and rural settlements.

Dialing Formats and Call Routing

For domestic calls within Mexico, the national trunk prefix is '01' when dialing from a landline, followed by the area code and the local seven-digit subscriber number. Thus, a local call from another state to a number in the 595 region would be dialed as: 01 595 XXX XXXX. However, when calling from a mobile phone in Mexico, the national dialing format simplifies to: 595 XXX XXXX (without the '01' prefix). For international callers, the format is: +52 595 XXX XXXX, where the plus sign represents the international access code from the caller's country.

Local calls within the same area code do not require the area code; subscribers can dial the seven-digit number directly. However, due to the implementation of the national numbering plan, all calls to geographic numbers in Mexico now require the area code even for local calls when dialing from mobile networks.

Administrative and Regulatory Context

The allocation and management of geographic area codes in Mexico fall under the jurisdiction of the Instituto Federal de Telecomunicaciones (IFT), the country's telecommunications regulatory body. Area code 595 is classified as a geographic code, meaning it is tied to a specific physical location. This is distinct from non-geographic codes used for mobile services (e.g., 55, 81) or toll-free numbers (e.g., 800). The geographic nature of 595 implies that calls are routed based on the destination's physical location, and tariffs may vary depending on the caller's origin.

Practical Guidance for Callers

When placing an international call to a number in the 595 region, ensure you have the correct country code (+52), area code (595), and the seven-digit local number. For example, a complete international dialing sequence would be: +52 595 123 4567. If you are within Mexico but outside the 595 area, use the national long-distance prefix '01' followed by 595 and the local number. For mobile-to-mobile calls, simply dial 595 and the number. It is important to verify the number length: all Mexican geographic numbers have seven digits after the area code, and the total national significant number length is ten digits (excluding the country code).

For businesses or individuals in the region, having a 595 number establishes a local presence, which can be beneficial for customer trust and local marketing. However, with the rise of VoIP and mobile services, geographic numbers are no longer strictly tied to physical lines, but the area code still reflects the original allocation zone.
