Complete guide to calling Mexico — international dialing code, step-by-step instructions, and FAQ.

How to Call Mexico from Abroad

About Mexico Calling Code

To reach Mexico from another country, first dial the international calling code +52 — assigned by the ITU — followed by the local number. Mexico is located in North America, in Northern America.

Mexico is known locally as México — Ciudad de México is the capital. When saving an international contact, write the number in full international format with +52 so it works from any country.

International calling codes follow the ITU-T standards E.123 and E.164, which define how phone numbers are written and dialed across borders. The prefix you dial after the exit code tells the global telephone network which national network to route the call to.

Where the +52 Calling Code Is Used

The country code +52 is assigned to Mexico, located in Northern America, with the capital Ciudad de México. This code is part of the international telephony numbering plan and is used for all calls made to Mexico from outside the country.

When a number is written as +52 …, the +52 prefix directs your call to the Mexico national network. After the prefix, dial the area code without its leading zero, then the subscriber number — the same pattern for landlines and mobiles.

ITU-T E.164 groups calling codes by world region; codes beginning with 5 cover the part of the world that includes Mexico, in Northern America. Storing numbers with +52 and omitting the domestic leading zero keeps contacts dialable from anywhere.

Mexico Phone Number Formats

The ITU E.164 format for Mexico numbers is +52 + area code + subscriber number, used for landlines and mobiles alike. Here is the general structure:

Numbering plans vary: closed plans use fixed-length national numbers, while open plans allow variable lengths with a trunk prefix (usually 0) that is dropped for international calls. For calls to Mexico, replace the trunk zero with +52.

Time Zone in Mexico

The local time in Mexico follows the America/Mexico_City time zone (UTC-06:00 UTC). Check the time difference before you dial so your call arrives during waking hours.

Time differences matter when calling Mexico: if it is UTC-06:00 there, a morning call from Europe may reach Ciudad de México in the afternoon, while callers in the Americas should check the offset to avoid late-night calls.

If Mexico observes daylight saving time, its UTC offset shifts by an hour twice a year. Double-check the current offset before time-sensitive calls, especially in spring and autumn.
