Area Code 716: Geographic Coverage and Administrative Jurisdiction
Area code 716 is a geographic National Destination Code (NDC) assigned to the State of Mexico (Estado de México), one of the 32 federal entities of Mexico. This NDC serves a portion of the state's territory, primarily covering municipalities in the eastern and northeastern parts of the state, bordering Mexico City (CDMX). The area is part of the greater Mexico City metropolitan area, and the code is used for fixed-line (PSTN) services, including residential, business, and government lines.
Primary Cities and Localities Served
The 716 area code covers several important municipalities, including but not limited to:
- Ecatepec de Morelos – one of the most populous municipalities in Mexico.
- Nezahualcóyotl (Ciudad Nezahualcóyotl) – a densely populated urban area.
- La Paz – a municipality east of CDMX.
- Chimalhuacán – another large municipality in the region.
- Los Reyes Acaquilpan – part of the La Paz municipality.
These areas are fully integrated into the Mexico City urban sprawl, and the 716 code is one of several NDCs serving the State of Mexico, alongside others like 55 (Mexico City proper) and 599 (other parts of the state).
Dialing Formats and Caller Instructions
For local calls within the same area code (716), callers must dial the 8-digit local number directly, without the area code. For example, to call a local number in Ecatepec, you would dial 1234-5678.
For calls from other area codes within Mexico, you must dial the national long-distance prefix 01, followed by the area code and the local number. For instance, to call a number in Ecatepec from Mexico City (area code 55), you would dial 01 716 1234-5678.
For international callers, the format is: +52 716 1234-5678 (or 011 52 716 1234-5678 from the US/Canada). The country code for Mexico is +52, and the area code 716 is dialed without any leading zero.
Overlay Considerations and Numbering Plan
As of the latest ITU-T E.164 national numbering plan, area code 716 does not have an overlay code; it is a standalone NDC. However, due to the high demand for numbers in the Mexico City metropolitan area, the Mexican telecom regulator (Instituto Federal de Telecomunicaciones, IFT) has implemented number pooling and other conservation measures. It is essential to note that the 716 area code is exclusively for geographic fixed-line services; mobile numbers in Mexico use the non-geographic prefixes 1, 2, 3, etc., and are not tied to a specific area code.
Practical Guidance for Callers
When calling a 716 number from abroad, ensure you have the correct country code (+52) and drop any leading '0' that might appear in local listings. For example, a number listed as (716) 123-4567 locally should be dialed internationally as +52 716 123 4567. Always confirm the number with the recipient, as the State of Mexico has multiple area codes, and a wrong code may route your call to a different region.
