Q&A for How to Call Mexico from the United States

People often call Mexico if they have friends or family living there, and would like to keep in touch. Some people might also call Mexico to schedule vacations or get information about a job or college that is located there.

646 is the area code for Ensenada. If you are calling from the US, add that before your number.

If the US cell has coverage in Mexico through its provider, the number will not change. Dial the number as you normally do and it will work.

It is 664.

Inquire at your local USA post office -- they can answer your specific question.

If the United States cell phone that you are calling from while in Mexico has an international plan (or a roaming plan), you should be able to dial back to the United States just like you would do on a regular call.

First, your cell phone company must provide that service. Not all companies permit out-of-country connections. Dialing is the same as from a land line: 1 plus the 3 digit area code plus the 7 digit number.

Dial “00” then 1, then the US area code and phone number: 00-1-(xxx)xxx-xxxx.
