📍 Geographic Location of Chiapas
Geographic Coverage and Administrative Jurisdiction
The area code 919 is a geographic National Destination Code (NDC) assigned to the state of Chiapas, Mexico, under the country calling code +52. Chiapas is located in the southeastern part of the country, bordering Guatemala. The code serves the capital city of Tuxtla Gutiérrez and its metropolitan area, as well as surrounding municipalities within the state. It is important to note that while 919 is the primary code for Tuxtla Gutiérrez, other regions in Chiapas may use different area codes (e.g., 961 for San Cristóbal de las Casas, 967 for Comitán). The administrative jurisdiction falls under the Federal Telecommunications Institute (IFT), which regulates numbering resources in Mexico.
Dialing Formats and Caller Instructions
For local callers within the 919 area code, the national dialing format requires dialing the 3-digit area code followed by the 7-digit local subscriber number: 919 XXX XXXX. For example, to call a landline in Tuxtla Gutiérrez, you would dial 919 123 4567. For callers from other parts of Mexico, the same format applies: dial 919 followed by the 7-digit number. International callers must dial Mexico's country code +52, then the area code (without the leading zero, as Mexico uses a single-digit trunk prefix '0' that is not part of the international format), and the local number: +52 919 XXX XXXX. For instance, an international caller would dial +52 919 123 4567.
Overlay and Numbering Considerations
As of the latest IFT updates, the 919 area code does not have an overlay code; it is the sole geographic code for Tuxtla Gutiérrez and its immediate surroundings. However, due to growing demand for telecommunication services, the IFT periodically reviews numbering resources. Subscribers should be aware that number portability is available in Mexico, allowing users to retain their numbers when switching service providers, but the geographic significance of the code remains tied to the original location.
Practical Information for Callers
When calling from abroad, it is essential to replace the international access prefix (e.g., 011 from the US/Canada) with the + sign or the appropriate IDD prefix. For example, from the US, you would dial 011 52 919 123 4567. From mobile phones, using the + sign is recommended for international calls. For local calls within the 919 area, dialing the area code is mandatory even for calls within the same city, as per Mexican dialing regulations. This ensures proper routing through the PSTN and mobile networks.
