📍 Geographic Location of Chiapas
Geographic Coverage and Administrative Jurisdiction
The area code 992 is a geographic National Destination Code (NDC) assigned to the state of Chiapas, Mexico. It serves the central-western portion of the state, with the city of Tuxtla Gutiérrez as its primary urban center. The code covers the capital city and its metropolitan area, including municipalities such as Chiapa de Corzo, Berriozábal, and Ocozocoautla de Espinosa. As a geographic code, it is tied to the PSTN (Public Switched Telephone Network) numbering plan and is administered under the jurisdiction of the Instituto Federal de Telecomunicaciones (IFT), Mexico's regulatory authority.
Dialing Formats and Caller Instructions
For callers within Mexico, the national long-distance format requires dialing the long-distance prefix 01, followed by the area code and the local number. For example, to reach a landline in Tuxtla Gutiérrez, you would dial: 01 992 XXX XXXX. For international callers, the format is the country code +52, then the area code (without the leading '0' or '01'), and the local number: +52 992 XXX XXXX. Local calls within the same area code may be dialed using only the seven-digit local number, depending on the specific carrier and local dialing regulations. It is important to note that Mexico has implemented overlay and number portability, so a number with prefix 992 may have been ported to a different geographic region or even to a mobile network; however, the geographic rate and routing principles generally apply.
Numbering Structure and Technical Considerations
Mexican geographic numbers consist of a three-digit area code followed by a seven-digit subscriber number, totaling ten digits for national dialing (excluding the long-distance prefix). The 992 code is part of the North American Numbering Plan (NANP) but uses its own country code, +52, and does not follow the NANP format of +1. The code is exclusively for fixed-line services, although some VoIP providers may offer numbers with this code for virtual presence. Callers should be aware that rates for calling a 992 number are typically based on the distance from the caller's location, though many carriers now offer flat-rate national calling plans.
Practical Examples
- Local call (within Tuxtla Gutiérrez): Dial XXX XXXX (seven digits).
- National long-distance call (from Mexico City): Dial 01 992 XXX XXXX.
- International call (from the United States): Dial 011 52 992 XXX XXXX or +52 992 XXX XXXX from a mobile phone.
