How to Call Mexico
The Mexico country code is +52. Learn how to call Mexico from any country with exit codes, dialing formats, area codes, and cost tips.
The country code for Mexico is +52. To call Mexico from abroad, dial your country's exit code, then 52, then the 10-digit Mexican phone number. Mexican numbers already include the area code, so there are no extra prefixes to add. Since a nationwide dialing reform in August 2019, mobiles and landlines follow the exact same format.

The country code for Mexico
What is the country code for Mexico?
Mexico's international dialing code is +52. Here's the quick reference for everything you need before you dial.
| Detail | Value |
|---|---|
| Country code | +52 |
| ISO codes | MX / MEX |
| Trunk prefix | None |
| Phone number length | 10 digits (area code included) |
| Emergency number | 911 |
Good to know: Mexico reformed its dialing plan in August 2019. The old 01, 044, and 045 prefixes are gone, and you no longer add a 1 after +52 when calling a Mexican mobile. Every number is now dialed the same way, whether it's a landline or a cell phone.

How to call Mexico
The dialing format is the same for every Mexican number. Dial your exit code, then 52, then the 10-digit number.
- Dial your exit code. This tells your carrier the call is international. From the US or Canada, dial 011. From most of Europe, dial 00.
- Dial 52. This is the Mexico country code.
- Dial the 10-digit number. The area code is already part of the number, so dial it exactly as written.

What a Mexico number looks like
Every Mexican phone number has three parts. The country code +52, an area code of two or three digits, and a local number of seven or eight digits. The area code and local number always add up to 10 digits.
Landline
+52 55 1234 5678
+52 is the country code, 55 is the Mexico City area code, and 1234 5678 is the local number.
Mobile
+52 55 8765 4321
Mobiles use the same 10-digit format as landlines. No prefix or 1 after +52 is needed.
| Number type | Format from abroad |
|---|---|
| Mexico City landline | +52 55 XXXX XXXX |
| Monterrey landline | +52 81 XXXX XXXX |
| Guadalajara landline | +52 33 XXXX XXXX |
| Cancun landline | +52 998 XXX XXXX |
| Mobile | +52 + 10 digits |
Formatting Mexican numbers for WhatsApp
WhatsApp is the default messaging app in Mexico, so you'll often add Mexican contacts there. Save the number in full international format with the plus sign, country code, and all 10 digits. For example, +525512345678. Skip the spaces and never add a 1 after 52. If you manage business contacts at scale, Telnyx Phone Numbers gives you local Mexican numbers your contacts can call back at domestic rates.
Good to know: Some older contact lists still show Mexican mobiles saved as +52 1 followed by 10 digits. That format was retired in 2019. Delete the 1 and the number will work everywhere, including WhatsApp.
Mexico area codes, toll-free, and emergency numbers
Mexico uses two-digit area codes for its three largest metro areas and three-digit codes everywhere else. These are the codes you're most likely to dial.
| City | Area code |
|---|---|
| Mexico City | 55 |
| Monterrey | 81 |
| Guadalajara | 33 |
| Cancun | 998 |
| Tijuana | 664 |
| Merida | 999 |
Special numbers
| Number type | Prefix | Notes |
|---|---|---|
| Emergency | 911 | Police, fire, and medical nationwide |
| Toll-free | 800 | Free within Mexico only |
| Premium rate | 900 | Higher charges apply |
Keep in mind: Mexico's 911 only works inside Mexico. And Mexican 800 numbers are usually unreachable from abroad, or your carrier will bill them as a regular international call. Ask the business for a standard geographic number instead.
Cost and best time to call Mexico
What you pay depends on how you call. Traditional carriers charge per-minute international rates that add up fast. VoIP and calling apps are far cheaper, and for businesses making regular calls, SIP Trunking brings the per-minute cost down to a few cents or less.
| Calling method | Typical cost |
|---|---|
| Traditional landline carrier | $0.20 to $2.00 per minute |
| Mobile carrier international plan | Often included or a monthly add-on |
| VoIP or SIP trunking | A few cents per minute, usage-based |
| WhatsApp or calling apps | Free over Wi-Fi or data |
Best time to call Mexico
Most of Mexico, including Mexico City, runs on Central Standard Time (UTC-6) year-round after the country ended daylight saving in 2022. Only some northern border cities still shift clocks to match the US.
| Your location | Time difference (Mexico City) | Best window to call |
|---|---|---|
| US Eastern | 1 to 2 hours ahead of Mexico | 10 a.m. to 6 p.m. your time |
| US Pacific | 1 to 2 hours behind Mexico | 8 a.m. to 4 p.m. your time |
| UK | 6 to 7 hours ahead of Mexico | 3 p.m. to 10 p.m. your time |
Good to know: Mexican business hours typically run 9 a.m. to 6 p.m., often with a longer midday break. Late morning local time is the most reliable window to reach someone.
Is calling Mexico free?
Sometimes. Many US and Canadian mobile plans now include unlimited calling to Mexico, so check your plan before paying for anything extra. App-to-app calls over WhatsApp are free on Wi-Fi. If your plan doesn't cover Mexico, a VoIP service is the cheapest way to dial regular Mexican numbers.
