and +52 Country Code
Mexico uses country calling code +52 and uniform ten-digit national dialing for fixed and mobile numbers. Legacy LADA prefixes remain widely recognized as historic city associations, but modern zone-based allocation and portability mean that a prefix is not proof of a number’s exact location or carrier.

How the Plan Developed
Uniform ten-digit dialing began on 3 August 2019 and became the sole national format on 3 August 2020, removing 01, 044, 045 and the extra international mobile digit 1. Since 1 July 2025, numbering resources have been administered through eight broad zones.
Coverage and identity limitation
Every city association on this site is described as historical or common, not exclusive. Providers can use numbering resources elsewhere within the applicable zone, and a number can move through portability or service changes.
Common questions
Mexico Phone Code FAQ
What is the country calling code for Mexico?
Mexico uses country calling code +52.
Do I keep the domestic prefix when using +52?
Use the complete national number after +52; no separate domestic trunk zero is used in the featured format.
Can an area code identify a caller’s exact location?
No. It describes a numbering area or historic allocation, and portability, forwarding and internet telephony can separate a number from the caller’s present location.
