📍 Geographic Location of Puebla
Overview of Area Code 276
Area code 276 is a geographic numbering plan area (NPA) within the Mexican national numbering plan, assigned to the state of Puebla. It serves as a National Destination Code (NDC) for fixed-line telephone services in the central-eastern region of Mexico. The code covers the city of Puebla de Zaragoza, the state capital, and its surrounding metropolitan area, including municipalities such as San Andrés Cholula, San Pedro Cholula, Cuautlancingo, and Amozoc. These localities form part of the Greater Puebla conurbation, one of the most populous urban areas in Mexico.
Geographic Coverage and Administrative Jurisdiction
The 276 area code is allocated to the state of Puebla, which is administratively divided into 217 municipalities. The primary service area is the Puebla Valley, with the urban core in the capital city. The region is an important industrial and commercial hub, hosting automotive, textile, and food processing industries, as well as numerous educational institutions. The coverage extends to both residential and business fixed lines, including PSTN and VoIP services that are assigned geographic numbers.
Dialing Formats and Caller Instructions
For local callers within the 276 area code, dialing a number requires only the seven-digit local subscriber number. For example, to reach a local line with the number 123-4567, a caller within the same area code would dial 123-4567.
For national long-distance calls from other area codes in Mexico, callers must dial the long-distance prefix 01, followed by the area code and the subscriber number. For instance, to call a Puebla number from Mexico City, you would dial 01 276 123 4567.
For international callers, the format is the Mexican country code +52, followed by the area code and the subscriber number, without the leading '01'. Thus, an international caller would dial +52 276 123 4567. When calling from a mobile phone in Mexico, the same international format is often used, especially for calls to fixed lines.
Overlay and Numbering Considerations
As of the latest ITU-T E.164 guidelines, the 276 area code does not have an overlay. The state of Puebla is served by multiple area codes, including 222 for the city of Puebla and 276 for the surrounding region. This separation helps manage numbering resources efficiently. Number portability is available in Mexico, allowing users to retain their numbers when switching service providers, but the geographic assignment remains tied to the physical location of the line.
