Telephone numbers in Mexico


Full numbering dial plan

All telephone numbers in Mexico are ten digits long. The Plan Técnico Fundamental de Numeración issued on September 4, 2018, introduced a ten-digit full numbering scheme, where the first digit denotes a geographical area of the country:
The current national number was formed by prepending the area code to the previously existing local number. All ten digits must be dialed, even for local calls.

Dialing prefixes

Since August 3, 2019, only the following dialing prefixes are available for use within Mexico:

Some mobile phones, which may be used from different countries, allow numbers to be dialed and stored with the prefix "+", which works for any current location.

Phone numbers and area codes

Until August 3, 2019, phone numbers in Mexico consisted of ten digits with either two-digit area codes 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, Leon, Mexico City, and Tijuana.
