📍 Geographic Location of Estado de Mexico
Overview of Area Code 726
Area code 726 is a geographic numbering plan area within the Mexican national numbering plan, administered under the country code +52. It serves a portion of the Estado de Mexico (State of Mexico), one of the 32 federal entities of Mexico. This state surrounds Mexico City on three sides and is part of the Greater Mexico City metropolitan area, though the 726 code covers more rural and semi-urban zones to the northeast of the capital.
Geographic Coverage and Jurisdiction
The 726 area code is assigned to municipalities in the northeastern part of the State of Mexico, including but not limited to: Acolman, Axapusco, Chiautla, Chiconcuac, Chimalhuacán (partial), Ecatepec de Morelos (partial), Hueypoxtla, Jaltenco, Nextlalpan, Nopaltepec, Otumba, San Martín de las Piramides, Tecámac, Temascalapa, Teotihuacán, Tepetlaoxtoc, Tequixquiac, Texcoco (partial), Tezoyuca, Tonanitla, and Zumpango. These municipalities are part of the greater Mexico City conurbation but retain their own local governance and administrative identity.
Dialing Formats
For local calls within the 726 area code, callers must dial the 3-digit area code followed by the 7-digit local number. The full national number is 10 digits, and the international format includes the Mexican country code +52. For example, a local number in Tecámac might be 726 123 4567. To call from abroad, dial +52 726 123 4567. When calling from another area code within Mexico, dial 01 726 123 4567 (the national long-distance prefix 01 is required).
Overlay and Numbering Considerations
The 726 area code is part of an overlay complex with area codes 55 and 59 in some regions, particularly in municipalities that border Mexico City. This means that within the same geographic area, multiple area codes may coexist, and 10-digit dialing is mandatory for all calls, even local ones. The overlay was introduced to expand numbering capacity without requiring existing subscribers to change their numbers.
Caller Instructions
For local callers within the 726 area code: always dial the 10-digit number (area code + local number). For callers from other parts of Mexico: dial 01 + 726 + local number. For international callers: dial your country's exit code (e.g., 011 from the US/Canada), then 52, then 726, then the 7-digit local number. Mobile callers within Mexico should dial the full 10-digit number directly, as mobile networks require it.
