Area Code 596 – Estado de Mexico

Overview of Area Code 596

Area code 596 is a geographic dialing code assigned to the State of Mexico (Estado de México), one of the 32 federal entities of Mexico. It serves a portion of the eastern part of the state, encompassing municipalities that are part of the greater Mexico City metropolitan area but lie outside the capital's federal district. The code covers a mix of urban and semi-rural communities, with a population that relies on both local commerce and commuting to Mexico City for employment and services.

Geographic Coverage and Key Localities

The 596 area code primarily serves the municipality of Amecameca and its surrounding areas, including towns such as Atlautla, Ayapango, Ecatzingo, Juchitepec, Ozumba, Tepetlixpa, and Tlalmanalco. These communities are located in the southeastern part of the State of Mexico, near the slopes of the Popocatépetl and Iztaccíhuatl volcanoes. The region is known for its natural landscapes, including the Izta-Popo National Park, and is a popular weekend destination for residents of Mexico City.

Dialing Formats and Procedures

For callers within Mexico, dialing a number in area code 596 requires the national long-distance prefix 01, followed by the area code and the local seven-digit number. The format is: 01 596 XXX XX XX. For example, to call a fixed line in Amecameca, you would dial 01 596 123 45 67.

For international callers, the Mexican country code is +52, so you would dial +52 596 XXX XX XX. For instance, from the United States, you would dial 011 52 596 123 45 67 or simply +52 596 123 45 67 from a mobile phone.

Local calls within the same area code do not require the prefix or area code; you can dial just the seven-digit number. However, if you are calling from a mobile phone, it is common practice to include the area code even for local calls to ensure proper routing.

Regulatory and Technical Considerations

Area code 596 is a geographic code, meaning it is tied to a specific physical location. It is administered by the Federal Telecommunications Institute (Instituto Federal de Telecomunicaciones, IFT) in accordance with the national numbering plan. As of the latest updates, there are no overlay codes or 10-digit dialing requirements in this region; the standard 7-digit local number format remains in effect. However, callers should be aware that number portability allows users to retain their numbers when switching service providers, but the geographic association of the code does not change.

For businesses and residents in the 596 area, the code is essential for establishing a local presence and ensuring that calls from within Mexico are routed correctly. It is also important for emergency services and public safety communications, as the code helps identify the geographic origin of a call.
