If you’re running a small business or startup and connecting with clients, contractors, or partners in Mexico, this guide will help you navigate the process confidently.

Whether you’re expanding your supply chain, outsourcing customer service, or tapping into a vibrant tech ecosystem south of the border, understanding how to call Mexico from the United States can save you time, money, and missed opportunities.

What’s the Mexico Country Code?

The Mexico country code is +52. This code is essential when dialing any Mexican number from outside the country, including from the United States. You’ll always start your call by dialing the US exit code (011), followed by 52, which tells the phone system to route your call to Mexico.

For example: If you're calling a business contact in Mexico City, your dialing sequence might look like this: 011-52-55-1234-5678 (landline) or 011-52-1-322-123-4567 (mobile).

How to Call Mexico from the US, Step by Step

The dialing process varies slightly depending on whether you’re calling a landline or mobile phone in Mexico.

For Mexican Landlines:

1. Dial 011 – This is the US exit code.
2. Dial 52 – The country code for Mexico.
3. Dial the area code – Usually 2 or 3 digits (e.g., 55 for Mexico City).
4. Dial the local number – Typically 7 or 8 digits.

Example: To call a landline in Mexico City, dial 011-52-55-1234-5678.

For Mexican Mobile Phones:

1. Dial 011 (or just use + on mobile).
2. Dial 52 (country code).
3. Add the digit 1 before the mobile number.
4. Dial the 10-digit mobile number.

Example: 011-52-1-322-123-4567 (for a mobile number in Puerto Vallarta).

Note: The “1” is required only when calling Mexican mobile phones from abroad.

Pro Tip

If you're dialing from a smartphone, simply press and hold the 0 key to insert a “+”, which replaces the international exit code (011). For example, instead of dialing 011-52-1-322-123-4567, you can enter +52-1-322-123-4567 and place the call directly.
