📍 Geographic Location of San Francisco Xonacatlan/Temoaya, MEX
Geographic Coverage and Administrative Context
The Mexican area code +52 719 is a geographic National Destination Code (NDC) allocated to the State of Mexico (Estado de México). Specifically, it serves the municipalities of Temoaya and San Francisco Xonacatlán, along with their surrounding localities. This region lies in the central highlands of Mexico, approximately 60 kilometers northwest of Mexico City, and is part of the greater Toluca metropolitan area. The code is administered under the Federal Telecommunications Institute (IFT) numbering plan, which follows ITU-T E.164 recommendations.
Dialing Formats and Caller Instructions
For local callers within Mexico, the prefix is dialed as 719 followed by the seven-digit local subscriber number. For example, to reach a landline in Temoaya, you would dial 719 XXX XXXX. However, when calling from a mobile phone within Mexico, it is standard practice to include the national trunk prefix '1' after the country code, resulting in +52 1 719 XXX XXXX. This format is also used for international callers, but the '1' is optional when dialing from abroad; both +52 719 XXX XXXX and +52 1 719 XXX XXXX will connect to the same subscriber.
For international callers, the complete international format is +52 719 XXX XXXX. This number must be dialed in its entirety, including the country code and area code, without any leading zeros. When calling from the United States or Canada, you may use the international access code '011' instead of '+', but the '+' notation is universally accepted on mobile devices.
Numbering and Overlay Considerations
All landlines within the 719 area code use seven-digit local numbers, making the total national significant number length ten digits (including the NDC). There are currently no overlay codes in this region, meaning 719 is the sole geographic code for Temoaya and San Francisco Xonacatlán. However, due to the proximity to Toluca, some numbers may be assigned to nearby communities that fall under the same local exchange area.
Practical Information for Callers
- Local calls: Dial 719 + local number (7 digits).
- National long-distance (from other Mexican area codes): Dial 01 719 + local number.
- International calls: Dial +52 719 + local number.
- Mobile calls within Mexico: Dial +52 1 719 + local number (or 044 719 + local number if calling from a Mexican mobile).
This area code is primarily used for fixed-line services, but number portability allows mobile subscribers to retain their numbers if they move to this region, though mobile numbers typically use non-geographic codes (e.g., 55, 56, etc.). For businesses, having a local 719 number establishes a presence in the Temoaya-Xonacatlán market and is essential for reaching local customers at local call rates.
