📍 Geographic Location of Puebla
Geographic Overview
The area code 275 is a geographic National Destination Code (NDC) assigned to the state of Puebla, Mexico. This code serves a specific region within the state, encompassing municipalities and localities that are part of the national numbering plan under ITU-T E.164. The primary cities and towns covered by this code include Ajalpan, Altepexi, Coxcatlán, Coyomeapan, Eloxochitlán, San José Miahuatlán, San Sebastián Tlacotepec, Tehuacán (in part), and Zinacatepec, among others. This area is located in the southeastern part of the state of Puebla, bordering the state of Oaxaca.
Dialing Formats
When dialing a number within the 275 area code from within Mexico, the national trunk prefix '01' is used, followed by the area code and the seven-digit local number. For example, to call a landline in Tehuacán from another part of Mexico, you would dial: 01 275 XXX XXXX.
For international callers, the format is: +52 275 XXX XXXX. The country code for Mexico is +52, and the area code is 275. The local number is seven digits long, making the total length of a national significant number (NSN) ten digits (including the area code).
Caller Instructions
- Local calls within the 275 area: If you are dialing from one landline to another within the same area code, you may need to dial only the seven-digit local number, depending on the local dialing rules. However, due to the introduction of overlay codes in some regions, it is recommended to dial the full ten-digit number (area code + local number) to ensure connectivity. Always check with your service provider for specific local dialing instructions.
- Calls from other parts of Mexico: Dial the national long-distance prefix '01', then the area code 275, followed by the seven-digit local number.
- Calls from outside Mexico: Dial your country's international access code (e.g., 011 from the US/Canada), then Mexico's country code 52, then the area code 275, and the seven-digit local number. For example, from the US, you would dial: 011 52 275 XXX XXXX.
Overlay Considerations
As of the latest numbering plan updates, there are no overlay codes currently assigned to the 275 area code. However, the Mexican telecommunications regulator (Instituto Federal de Telecomunicaciones, IFT) has implemented ten-digit dialing nationwide for all fixed-line and mobile services. This means that even for local calls, you should dial the full ten-digit number (area code + local number) to avoid any potential issues, especially as number portability and new services evolve.
Important Notes
This area code is used exclusively for fixed-line (PSTN) services. Mobile numbers in Mexico are assigned to non-geographic codes (e.g., 222, 221, etc.) and are not tied to a specific geographic area. If you receive a call from a number with the 275 prefix, it is a landline located in the specified region of Puebla. For emergency services, always dial 911 (national emergency number) regardless of the area code.
