Here’s how to call Mexico from the USA in four simple steps:

  1. Enter + or 011 on your phone keypad

    This is the code that tells your mobile phone carrier (+ for mobile and VoIP carriers) or landline provider (011 if you have a landline phone) that you’re making an international phone call.

  2. Enter 52

    This is the Mexico country code, which gets you through to the right country.
    Remove the trunk code: Mexican telephone numbers begin with one of three trunk

  3. Remove the trunk code

    Mexican telephone numbers begin with one of three trunk codes: 01, 044, or 045. Ignore this portion of the number. This prefix is only needed for domestic calls, not for international dialing.

  4. Enter the phone number, including the area code

    Mexican phone numbers are 10 digits long, including the two-digit or three-digit area code.

If your call isn’t going through, contact your carrier to ensure you have international calling enabled. Some carriers may require additional steps to call international numbers.

What Mexican area code should I use?

Much like in the United States, Mexico assigns area codes to different regions of the country.

If you receive a phone number without an area code, but you know where the person or business you want to call is located, you can use the table below to figure out the right area code for major parts of Mexico.

Examples of how to call Mexico from the USA

To help you understand how to call Mexico from the USA, we’ll look at some examples.

Let’s say you want to call a cell phone number in Cancun that’s typed out as 045 998 555 5555. You’d apply the steps we outlined above in the following way:

  1. Enter + (if you’re calling from a mobile number or OpenPhone) or 011 (if you’re dialing from a landline).
  2. Add on the Mexico country code, 52.
  3. Remove the”045″ from the number.
  4. Type the remaining digits of the number, including the 998 area code (998 555 5555).

By the time you dial, you should have this number typed on your phone if you’re calling from a mobile or VoIP number: +52-998-555-5555.

The process would be exactly the same if the number you wanted to reach were a landline number instead of a mobile number.

Now, let’s say you wanted to call a phone number in Guadalajara. This region has a two-digit area code (33) followed by eight digits, but the steps are still the same. If the phone number is written out as 044 33 1234 5678, you’d follow the steps this way:

  1. Enter + (when calling from a mobile number or OpenPhone) or 011 (when calling from a landline). 
  2. Add on 52.
  3. Remove “044” from the number.
  4. Type the remaining digits of the number, including the 33 area code (33 1234 5678).

When you dial, you should have this number typed in: +52-33-1234-5678.

How much does it cost to call Mexico from the US?

When you’re calling from a landline or cell phone, international calls don’t come cheap. For example, AT&T’s basic rate for calls to Mexico is $3.50 per minute on landlines as of September 2020. Using a cell phone? Make that $3.65 per minute.

Even on an international calling plan, which requires you to pay a monthly fee, you’ll still have to pay 9 cents per minute to call Mexico from a US landline phone or 24 cents per minute from a US mobile phone.

These rates may be fine if you’re making a monthly call to a grandma in Mexico. But if you need to make calls to Mexico for business — which may involve dozens of clients, business partners, and suppliers — the costs can add up. Luckily, there is a way to cut down on expenses.

How to make affordable business calls to Mexico from the US
