Telephone numbers in Mexico

Full numbering dial planEdit

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:

  • 2 East
  • 3 West
  • 4 North
  • 5 Center (Mexico City Metropolitan Area)
  • 6 Northwest
  • 7 South
  • 8 Northeast
  • 9 Southeast

The current national number was formed by prepending the area code to the previously existing local number.[1] All ten digits must be dialed, even for local calls.

Dialing prefixesEdit

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

Prefix Use Format Digits after prefix
00 International direct dialing 00 + country code + local phone number -
- Domestic direct dialing phone number 10

Dialing into MexicoEdit

To contact a (10-digit) Mexican phone number (landline or mobile) from another country, dial:

    + 52 (phone number, incorporating area code)

where the plus sign (+) represents the international access code of the country calling from, 00 for Europe and central America, 011 from the United States. 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 codesEdit

Until August 3, 2019, phone 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, Leon, Mexico City, and Tijuana.

For a list of all area codes, see area codes in Mexico by code.
