How Do I Dial A Mexican Phone Number

So you’re staring at a Mexican phone number. It looks innocent enough. Then you notice the plus sign, the country code, and suddenly you’re questioning every phone call you’ve ever made.

Deep breath. Dialing Mexico is easier than it used to be. Way easier.

The One Number You Actually Need: +52

Mexico’s country code is 52. That’s it. Not 521, not 52 followed by a secret handshake.

If you see +521 on an old contact card, don’t panic. That extra 1 is a relic from the mobile-dialing dark ages.

These days, you just use +52 and then the Mexican number’s 10 digits.

Calling from the US or Canada

From a regular landline, start with 011. That’s the international exit code for the US and Canada.

Then dial 52. Then dial the 10-digit Mexican number.

So a Mexico City number like 55 1234 5678 becomes 011 52 55 1234 5678.

From a cell phone? Even simpler. Just type +52 55 1234 5678.

The plus sign does the international heavy lifting for you. Fancy, right?

Calling from Anywhere Else

Your country has its own exit code. The US and Canada use 011. Most of Europe uses 00. Australia uses 0011. Japan uses 010.

Find your exit code, dial it, then 52, then the 10-digit Mexican number.

Or just use +52 from a mobile phone. That works in most places and saves you a Google search.

What About the Old 01, 044, and 045?

They’re retired. Gone. Sent to the dialing museum.

Mexico scrapped those prefixes back in 2019. You no longer need 01 for long distance.

You also don’t need 044 or 045 for mobile numbers. Landline, cell, tin can with a string—same rules now.

If someone hands you a number starting with 01, 044, or 045, just drop those first digits. Then dial the remaining 10-digit number.

Do You Need to Add a “1” for Cell Phones?

Nope. That was the old way. Please don’t add a 1 after 52.

How to Call Mexico from the US: Simple Steps for 2025

If you see +52 1 55 1234 5678, the 1 is a ghost. Dial +52 55 1234 5678 instead.

Your call will thank you. Or at least connect.

Calling a Mexican Number from Inside Mexico

Already in Mexico? Lucky you. Just dial the 10-digit number.

No country code. No 011. No 01. No 044 or 045.

If you’re calling a cell from a hotel landline, same deal: 10 digits.

If you’re calling another country from Mexico, then you dial 00, the country code, and the number. But that’s a different adventure.

How to Read a Mexican Phone Number

Mexican numbers are usually written as +52 followed by 10 digits.

Those 10 digits include the area code and the local number. Area codes can be two or three digits.

Mexico City uses 55. Guadalajara uses 33. Monterrey uses 81. Puebla uses 222.

Don’t try to split them wrong. Just dial all 10 digits after 52.

Quick Examples

Mexico City: +52 55 1234 5678.

Guadalajara: +52 33 1234 5678.

Puebla: +52 222 123 4567.

From a US landline, add 011 in front. From a cell, keep the plus sign.

Why Does the Number Look So Long?

Mexican numbers pack a lot into those 10 digits. The area code isn’t always the same length, which trips people up.

Mexico City’s code is just 55. Puebla’s is 222. Both end up as 10-digit numbers total.

So don’t count digits in chunks. Count to ten and dial.

Landline, Cell, or WhatsApp?

For regular calls, landlines and cells follow the same rules. That’s the beauty of the 2019 change.

But if you’re calling a friend who lives on WhatsApp, maybe just message them. Cheaper, faster, and you can send memes.

Still, for businesses, hotels, and official stuff, a real call is often best.

Watch Out for These Common Mistakes

Mistake one: dialing 521 instead of 52. The country code is 52, period.

Mistake two: leaving in the old 01, 044, or 045. Those are dialing fossils.

Mistake three: forgetting your own exit code when calling from a landline. Your phone won’t magically know you’re going international.

What If It Doesn’t Work?

Double-check the number. Maybe you added a 1 after 52. Maybe you kept an old 044.

Also check your phone plan. International calling isn’t always included, and your carrier might block the call.

WhatsApp, FaceTime, and Skype are solid backups. But for a real phone call, the steps above should get you through.

One Last Cheat Sheet

From US/Canada landline: 011 + 52 + 10-digit number.

From US/Canada cell: +52 + 10-digit number.

From anywhere else: your exit code + 52 + 10-digit number.

From inside Mexico: 10-digit number.

No 01. No 044. No 045. No extra 1.

And that’s it. You’re officially ready to call Mexico without sweating through your shirt.
