What's the country calling code for Mexico?

When dialling someone in Mexico City, Guadalajara, or Cancun from the UK, there are a few important steps you must follow to make sure you get connected.

This guide is designed to clear up any confusion. We explain the international code for Mexico (+52), walk you through the exact dialling steps for both landlines and mobiles, and share tips on saving money and avoiding common mistakes, whether you’re calling from home or using a Revolut eSIM while travelling.

Understanding the international code for Mexico

Making an international call requires a specific, multi-step sequence. The full sequence is essential to direct your call and ensure a successful connection.

The role of the international access code (00 or +)

Your call must begin with an international access code, also known as an exit code. This tells your phone company that the next digits are for a country outside of your own.

• Calling from a mobile phone: you should always start your sequence with +. This allows your phone company to redirect your call out of your country. Since most customers use mobile phones, this makes things simpler.
• Calling from a landline: you must start with 00 instead of +. This is the standard international exit code for the UK and many other countries.

The mandatory Mexico country code

Immediately following your exit code, you must dial the country code. In this case, you use the Mexico dialling code, 52.

Whether you begin with the landline exit code or the mobile + symbol, the combined sequence is the international dialling code for Mexico.

• Mobile full start: +52

Example: if the Mexican mobile number is 55 9988 7766, you'd dial +52 55 9988 7766.

• Landline full start: 00 52

Example: if the Mexican number is 55 1234 5678, you'd dial 00 52 55 1234 5678.

Understanding this format is the first step in mastering the Mexican phone number format.

How to call a Mexican phone number from the UK

Landline and mobile phone numbers in Mexico both have 10 digits, including the area code or mobile service provider code.

The general format you need to follow is:

• UK exit code or +
• Mexico country code: 52
• Full 10-digit Mexican number

Dialling Mexican mobile numbers

In 2019, Mexico simplified its system: the domestic prefix 01 (for long-distance) and the mobile prefix 1 (used before some older 10-digit mobile numbers) are no longer used.

New Mexican mobile number example: 55 9988 7766.

Previously, international mobile phone callers had to add an extra 1 after the country code (+52). This is no longer necessary. Now, just dial +52 followed by the complete 10-digit mobile number.

International mobile number example: +52 55 9988 7766.

Dialling Mexican landlines: the 10-digit structure

Mexican landlines are composed of a 2 or 3-digit area code (LADA) followed by a 7 or 8-digit local number, always totalling 10 digits. When dialling internationally, dial +52 followed by the 10 digits.

For example, if your contact in Mexico City provides the landline number 55 1234 5678, the international dialling code would be +52 55 1234 5678.

How to save your Mexican contacts

For seamless calling and messaging, especially when you're travelling or using apps, you should always save your Mexican contacts in the international format.

Always save the contact starting with the + symbol and the country code.

• Correct landline save (Mexico City): +52 55 1234 5678
• Correct mobile save: +52 55 9988 7766

This standard format ensures that apps and services correctly interpret the number, removing any need to manually adjust the format or exit code, regardless of your current location.

Why didn't my call to Mexico work?

Common dialling mistakes

If you tried to call a Mexican contact and your call failed, you've most likely made a common dialling mistake. Even with the Mexican country code entered correctly, other small mistakes in the sequence can stop your call from going to plan.

Mistake 1: using the mobile prefix 1

The most common error is forgetting that the rules have changed and you no longer need to add anything extra between the country code and the rest of the Mexican number. Remember to dial the 10-digit number immediately after +52 without adding any extra digits like 1 or 01.

Mistake 2: using the wrong exit code or omitting the country code

Forgetting the +52 code or using an incorrect UK exit code will stop your call from making it to Mexico. Make sure you check the full number you've dialled before making your call.

Mistake 3: the hidden costs of international calling

Even if your call connects, you might be shocked at how much it costs. If you're using a standard UK phone plan, calling someone in Mexico can incur significant per-minute charges.

Make sure you check your network provider's specific international calling rates to Mexico before you dial. This is especially important if you're travelling there from the UK. Relying on UK network roaming for calls and data in Mexico is notoriously expensive, which leads many customers to seek alternatives. Our Mexico eSIM data plan offers a digital solution, allowing you to instantly buy data plans in-app and bypass those costly traditional roaming fees.

What's the best time to call Mexico?

Mexico spans 3 different time zones, and crucially, it doesn't observe Daylight Saving Time (DST). This means the time difference between the UK and Mexico shifts throughout the year.

Navigating Mexican time zones

When the UK switches to BST in the summer, the time difference shrinks by an hour (e.g. Mexico City becomes 5 hours behind BST). Always do a quick online search to check the current time in the specific city you're calling.

When to call for business vs personal reasons

• Personal calls: the best time for people in the UK to call friends and family in Central Mexico is usually the afternoon (3–5pm GMT/BST). This is late morning/early afternoon in Mexico (9–11am CST), which is a good window outside sleeping hours.
• Business calls: for professional communication, you should aim for the afternoon in the UK (4pm GMT/BST). This is mid-morning in Mexico (10am CST), allowing time for a conversation during overlapping business hours.

Other Mexican phone number types (toll-free and emergency)

It's useful to know about 2 other types of numbers you might encounter:

• Toll-free numbers: these numbers usually start with 800 and are free to call from within Mexico. However, calling them internationally using the international dialling code for Mexico will likely incur charges or lead to connection issues.
• Emergency number: the standard emergency number in Mexico is 911. This number isn't diallable from overseas.

Frequently asked questions (FAQs)

What's the difference between +52 and 0052?
