To call a Mexican phone number from the United States or any other country, dial the international access code, then Mexico's country code (52), followed by the 10-digit Mexican phone number. Whether you are calling a landline or a mobile, the dialing sequence is now identical, and you can use "011" from a US landline or "+" from a mobile phone.
The simple way to call a mexican phone number
From the United States, the unified dialing formula for both landlines and mobiles is simple. From a landline, dial 011 52 followed by the 10-digit local number. From a mobile phone or VoIP service, dial +52 followed by the same 10-digit number. For example, to call a number in Mexico City, you would dial 011 52 55 1234 5678 from a landline or +52 55 1234 5678 from a mobile. This works for every Mexican phone number because all numbers are now 10 digits.
Understanding Mexico's 10-digit phone system
In 2019, Mexico unified its telephone numbering system. Previously, landline and mobile numbers required different dialing procedures, including an extra "1" after the country code for mobile numbers. Now, every Mexican phone number, whether landline or mobile, consists of exactly 10 digits. This 10-digit number includes a 2 or 3-digit area code (known as the LADA) followed by the local number. This change made the dialing process identical for both types of numbers, simplifying how to call a mexican phone number from abroad. When dialing a Mexican landline from within Mexico, you must dial the domestic long-distance prefix '01' before the area code and local number. When dialing a Mexican cell phone from within Mexico, you must dial the mobile prefix (clave lada nacional) before the local number.
Step-by-step: calling from a US landline
- Dial the US exit code: 011. This is the international access code for calls originating from the United States and Canada.
- Dial Mexico's country code: 52.
- Dial the full 10-digit Mexican phone number, including the area code.
For example, to call a landline in Mexico City with the local number 1234 5678 and area code 55, you would dial 011 52 55 1234 5678. Do not add any extra digits or omit the area code. When calling a Mexican landline from abroad, you must omit the initial zero from the area code.
Step-by-step: calling from a US mobile phone or VoIP
- Use the universal exit code: +. This symbol works on mobile phones and VoIP services as a standard international access code instead of "011".
- Dial Mexico's country code: 52.
For example, to call the same Mexico City number from a mobile, you would dial +52 55 1234 5678. The "+" key is usually accessed by holding down the "0" key on most phones.
A common mistake to avoid
A frequent error is adding a "1" after the country code, such as dialing +52 1 before the 10-digit number. This outdated prefix was discontinued in 2019 when Mexico unified its dialing system. Including it will cause your call to fail. Always dial +52 or 011 52 directly followed by the 10-digit number with no extra digits.
Checking your international calling rates
Before placing international calls, contact your service provider to understand potential per-minute costs. Carriers like T-Mobile offer specific international calling plans and rates that can vary significantly. Checking your international calling rates beforehand helps you avoid unexpected charges and choose the most cost-effective option for your call.
