Telephone numbers in Mexico are regulated by the Federal Telecommunications Institute, an independent government agency of Mexico. The agency published the Fundamental Technical Plan for Numbering (Plan Técnico Fundamental de Numeración) on May 11, 2013. The plan establishes a uniform ten-digit telephone number format. It took effect on August 3, 2019.
All telephone numbers in Mexico have ten digits, of which the first identifies one of the eight principal geographic regions of the country.
Prefix | Region |
---|---|
2 | East |
3 | West |
4 | North |
5 | Center (Mexico City metropolitan area) |
6 | Northwest |
7 | South |
8 | Northeast |
9 | Southeast |
The national number is formed by prefixing the previously existing local number format with an area code. All ten digits must be dialed for all calls.
Since August 3, 2019, only the following dialing prefixes are available for use within Mexico:
Prefix | Use | Format |
---|---|---|
00 | International direct dialing | 00 + country code + local phone number |
Destinations in Mexico are dialed from foreign location by dialing the foreign country's International access code (011 in the US, 00 in many other countries), the country code 52, and the ten-digit national telephone number of the destination.
Until August 3, 2019, telephone numbers in Mexico consisted of ten digits with either two-digit area codes (for Mexico City, Monterrey, and Guadalajara and their respective metropolitan areas) or three-digit area codes for the rest of the country. New area codes were assigned in the overlay format to address number exhaustion: in 2017, Toluca and Puebla and in 2018, León, Mexico City, and Tijuana.
In the early development of International Direct Distance Dialing (IDDD), Mexico elected to join World Zone 5, instead of joining the North American Numbering Plan (NANP). Since the 1960s, the Bell System had already established technical infrastructure to include Mexico in the NANP routing system, and continued to maintain special dialing arrangement using NANP area codes 903 (northwest Mexico) and 905 (Mexico City) from the US into Mexico, because of high community interest into the 1980s. Use of the area codes was formally discontinued on February 1, 1991, requiring callers to use international dialing.
