📍 Geographic Location of Puebla
Overview of Area Code 776
Area code 776 is a geographic National Destination Code (NDC) assigned to the state of Puebla, Mexico, under the country's national numbering plan administered by the Federal Telecommunications Institute (IFT). This code serves a significant portion of the state, including the capital city of Puebla de Zaragoza and its metropolitan area, as well as several surrounding municipalities. As a geographic code, 776 is tied to a specific region, and calls to numbers with this prefix are routed to the PSTN (Public Switched Telephone Network) infrastructure within that area.
Geographic Coverage and Cities Served
The 776 area code covers the central-western part of Puebla state, with the city of Puebla (the state capital) as the primary hub. It also serves municipalities such as San Andrés Cholula, San Pedro Cholula, Cuautlancingo, Amozoc, and Atlixco, among others. These areas form a densely populated corridor with significant commercial and industrial activity. The code is also used in some nearby towns and rural communities, reflecting the expansive reach of the numbering plan.
Dialing Formats and Instructions
For local callers within the 776 area code, calls to other 776 numbers can be made using the 7-digit local number (without the area code). However, for calls from other area codes within Mexico, the full national format must be used: 01 776 XXX XXXX. For international callers, the format is +52 776 XXX XXXX (or 011 52 776 XXX XXXX from the U.S. and Canada). It is important to note that Mexico has implemented an overlay and migration plan; as of 2020, the 222 area code (previously used for Puebla) was replaced by 776 for all new numbers, and existing 222 numbers were migrated to 776. Therefore, all numbers in the region now use 776.
Caller Instructions
For local callers: If you are dialing from a landline or mobile within the 776 area, you can dial the 7-digit number directly. For long-distance calls from other parts of Mexico, you must dial the long-distance prefix 01, then the area code 776, followed by the 7-digit number. For international callers: Dial your country's exit code (e.g., 011 from the U.S.), then Mexico's country code 52, then 776, and the 7-digit number. For example, to call a number in Puebla from the U.S., you would dial 011 52 776 XXX XXXX. If you are calling from a mobile phone, you can often use the +52 format directly.
Overlay and Numbering Plan Considerations
As part of Mexico's national numbering reform, the 776 area code is an overlay for the former 222 area code. This means that all numbers in the region now share the same 10-digit national format (including the area code). There is no longer a distinction between local and long-distance dialing for mobile calls; all calls, including local ones, require the full 10-digit number when dialed from a mobile phone. This change was implemented to increase the number of available numbers and to simplify dialing procedures. Users should ensure they update their contacts and business listings to reflect the new 776 area code.
