In another month, using the phone in Mexico will be a little simpler for everybody.

A long-running phase-in, changing the rules for calling in and out of Mexico, is complete Aug. 3, making phone numbers uniformly 10 digits.

That means no more 01, 044 or 045 prefixes. Only the area code and the local number is needed for either landlines and cellphones.


A call from abroad to a mobile number in Mexico will no longer need the number 1 before the area code.

Calling internationally from Mexico, first dial 00, then the country code, the city code and finally the number itself.

To call Mexico from abroad, dial that country’s access code to the international long distance service, then Mexico’s 52 country code, and the 10-digit telephone number.

The new way to call

  • As of Aug. 3, 2019, to reach a Mexican land line phone from another country, dial: 52 (local phone number).
  • To reach a Mexican cell phone from another country, dial: + 52 (local phone number). The plus sign represents the international access code of the country the call is coming from. For example, from Europe or Central America dial 00-52 first. From the United States of Canada, it’s 011-52, and then the local phone number.
  • From North America (United States or Canada) dial: 011 52 (local phone number)
  • To call an 800 line, or any other non-geographic number, dial 01 first.
