How to Call Mexico from the US: Complete 2026 Guide

Mexico is the most-called international destination from the United States, thanks to deep cultural ties, shared borders, and millions of families with connections on both sides. Whether you are reaching a relative in Mexico City, coordinating with a supplier in Monterrey, or checking in with friends in Guadalajara, this guide explains exactly how to call Mexico from the US — including the simplified dialing rules that took effect in 2019.

Quick Reference: Dialing Mexico from the US

The basic dialing format for calling Mexico from the United States is:

From a landline: 011 + 52 + 10-digit number

From a mobile phone: +52 + 10-digit number

Example (Mexico City): 011 52 55 1234 5678 or +52 55 1234 5678

Example (mobile): 011 52 55 1234 5678 or +52 55 1234 5678

Since 2019, Mexico eliminated the old requirement to dial "1" before mobile numbers. Now, all Mexican phone numbers — both landline and mobile — are dialed the same way: country code + 10-digit number.

Step-by-Step Dialing Instructions

How to call a landline in Mexico

Dial the exit code: Enter 011 from a US landline, or use the + symbol on your mobile phone.
Enter the country code: Dial 52 for Mexico.
Enter the 10-digit number: This includes the area code (2 or 3 digits) followed by the local number.

A complete call to a landline in Mexico City would look like: 011 52 55 XXXX XXXX or +52 55 XXXX XXXX.

How to call a mobile phone in Mexico

The process is identical to calling a landline. Mexico's 2019 numbering reform unified the dialing format, so you no longer need to insert a "1" before mobile numbers.

Dial 011 (or use +).
Dial 52.
Dial the full 10-digit number.

Example: +52 33 1234 5678 (a mobile in Guadalajara).

Using the + symbol

On any smartphone, hold the "0" key or tap + directly. This universal prefix replaces the 011 exit code and works from any country. For a full explanation of international dialing prefixes, see our complete international calling guide.

Mexico Area Codes and Major Cities

City	Area Code	Example Number
Mexico City	55	+52 55 XXXX XXXX
Guadalajara	33	+52 33 XXXX XXXX
Monterrey	81	+52 81 XXXX XXXX
Tijuana	664	+52 664 XXX XXXX

Cities with 2-digit area codes have 8-digit local numbers, while cities with 3-digit area codes have 7-digit local numbers. The total is always 10 digits after the country code.

Best Time to Call Mexico from the US

Mexico spans multiple time zones, from UTC-6 to UTC-8:

Central Time (UTC-6): Mexico City, Guadalajara, Monterrey — same as US Central Time.
Mountain Time (UTC-7): Chihuahua, Mazatlan — same as US Mountain Time.
Pacific Time (UTC-8): Tijuana, Mexicali — same as US Pacific Time.

This makes Mexico one of the easiest countries to call from the US in terms of scheduling. Most major Mexican cities share the same timezone as their closest US counterparts.

For personal calls, evening hours work well since time zones closely align. For business calls, standard business hours (9:00 AM - 6:00 PM) overlap almost perfectly between the two countries, especially for central and eastern US callers reaching Mexico City.

Tips for Calling Mexico

Forget the old "1" rule. Before 2019, you had to dial 1 after the country code when calling Mexican mobile numbers. This is no longer required. Simply dial +52 followed by the 10-digit number for both landlines and mobiles.
Check if your carrier includes Mexico. Some US carriers like T-Mobile include calls to Mexico in their standard plans. Verify your plan details before paying for a separate service.
Use WhatsApp for free calls. WhatsApp is the dominant messaging platform in Mexico. If your contact uses it, you can make free voice and video calls over Wi-Fi or data. Learn more about free international calls.
Take advantage of aligned time zones. Mexico's time zones mirror those of the US, making it convenient to call during normal waking hours without complex time calculations.

FAQ

Is calling Mexico from the US considered an international call?
