Determine the time at the destination where you are calling. Most of Mexico falls within the Central Time Zone, but some also are within the Mountain and Pacific areas. This can make a difference, particularly when calling from the Eastern Time Zone.
When calling from the United States, the international access code is 011. When calling from other international locations, the access code is 00.
Dial 52. This is the country code for Mexico.
Leave the first 0 out of the phone number. Many times it will look like this (0) when it is listed. This is the first number needed for a city or regional area code when calling from within the country.
Dial the rest of the numbers.
