Calling the United States from Mexico requires a slight modification to the dialing process. To make a call, follow these steps:
- Dial the exit code for Mexico, which is 00.
- Dial the country code for the United States, which is 1.
- Dial the area code of the city you are calling in the United States.
- Dial the local phone number.
For example, to call a landline in New York City, you would dial: 00 1 212 XXX XXXX.
